Building car-dependent neighborhoods

Also published on Resilience

Car-dependent neighbourhoods arise in a multi-level framework of planning, subsidies, advertising campaigns and cultural choices. After that, car dependency requires little further encouragement. Residents are mostly “locked-in”, since possible alternatives to car transport are either dangerous, unpleasant, time-consuming, or all three.

At the same time, municipal officials have strong incentives to simply accept car dependency – it takes bold new thinking to retrofit such neighbourhoods. Voters are likely to resist such new directions, since it is hard for them to imagine making their daily rounds using anything except private cars.

This post continues a discussion of what car dependency looks like on the map. The previous installment looked at car dependency on a regional scale, while this one looks at the neighbourhood scale.

Both posts use examples from Durham Region, a large administrative district on the east flank of Toronto. With a current population of about 700,000, Durham Region is rapidly suburbanizing.

I’ve picked one neighbourhood to illustrate some common characteristics of car-dependent sprawl. I have chosen not to name the neighbourhood, since the point is not to single out any specific locale. The key features discussed below can be seen in recent suburban developments throughout Durham Region, elsewhere in Ontario, and around North America.

Let’s begin to zoom in. In the aerial view below you can see new subdivisions creeping out towards a new expressway. Brown swatches represent farmland recently stripped of topsoil as the first step in transforming rich agricultural land into suburban “development”. (In the short time since this aerial imagery was obtained, the brown swatches have become noticeably more extensive.)

The neighbourhood we’ll focus on includes a high school, conveniently identifiable by its distinctive oval running track.

Subdivisions here are built in a megablock layout, with the large-scale grid intended to handle most of the traffic. Within each megablock is a maze of winding roads and lots of dead-ends. The idea is to discourage through traffic on residential streets, but this street pattern has many additional consequences.

First, from the centre of one megablock to the centre of another nearby megablock, there is seldom a direct and convenient route. A trip that might be a quarter of a kilometer as the crow flies might be a kilometer or two as the car drives. In the worst areas, there are no available short cuts for cyclists or pedestrians either.

Second, the arterial roads need to be multilane to cope with all the traffic they collect – and as “development” proceeds around them they are soon overwhelmed. “Recovering engineer” Charles Marohn explains this phenomenon using an analogy from hydrology. At a time of heavy rain, a whole bunch of little streams feed into progressively larger streams, which soon fill to capacity. With a pattern of “collector” roads emptying into secondary arterial roads into primary arterials and then into expressways, suburban road systems manage to engineer traffic “floods” each time there is a “heavy rain” – that is, each morning and afternoon at rush hour.1

As we zoom in to our high school’s neighbourhood, note another pattern repeated throughout this region. Within a residential neighbourhood there may be a row of houses close to and facing an arterial road. Yet these houses are on the equivalent of a “service road” rather than having direct access to the arterial. For motorists living here the first stage of a journey, to the arterial road just 50 meters from their driveway, requires driving ten times that far before their journey can really begin. Though the maze pattern is intended to limit traffic in such neighborhoods, residents create a lot of traffic simply to escape the maze.

The residential service road pattern has the effect of making arterial roads into semi-controlled-access roads. As seen in this example, there are few driveways or other vehicle entry points in long straight stretches of such an arterial. This design encourages drivers to drive well above the posted 60 km/hr speed limit … whenever the road is not clogged with rush-hour traffic, that is.

High traffic speeds make crossing such roads a dangerous undertaking for pedestrians and cyclists. True, there are some widely-spaced authorized crossing points, with long waits for the “walk” light. But when getting to and waiting at a crosswalk is not convenient, some people will predictably take their chances fording the rushing stream at other points. How many parents will encourage or even allow their children to walk to school, a playground, or a friend’s house if the trip involves crossing roads like these?

Just across the road. High school is on the left of the road, residential neighbourhood to the right.

Pedestrian access is at best a secondary consideration in such developments. Consider the aerial view below.

Directly across one arterial road from the high school, and across another arterial from a residential neighbourhood, is a cluster of big box retail stores including a Walmart Supercentre. The Walmart has 200 meters of frontage on the street, but in that stretch there is no entrance, nothing but concrete wall to greet the occasional lonesome pedestrian.

From another direction, many people live “just across the street” from the Walmart and other stores. Except … would-be pedestrian shoppers will need to cross not just a multilane urban highway, but also hectares of parking lot, before reaching the doors of a store. These stores are large in retail floor area, but they are dwarfed by the land given to parking. In accord with minimum parking requirements, the stores have spent hundreds of thousands of dollars to provide “free parking”. But there is no requirement to take the convenience of pedestrians into account. The doors open to the parking lots, not to the streets, because the vast majority of shoppers will arrive in large private vehicles that will need to be stored somewhere while the owner goes shopping.

Nevertheless there will be a small minority in such neighbourhoods who get to the store on foot or on bike. A few might be brave, stubborn environmentalists or exercise freaks. But mostly they will be people who can’t afford a car, or who can’t drive because of some type or degree of disability. Disproportionately, they will be elderly and/or in poor health. Particularly when carrying heavy bags of groceries, they will not want to go far out of their way to get to a crosswalk, preferring instead to make the shortest straightest trip home. It is not an accident that high-volume arterial roads in suburbs account for a large proportion of pedestrian deaths in North American cities. It is not an accident, either, that a disproportionate number of these deaths are inflicted on elderly, disabled, poor, or racially disadvantaged pedestrians.2

Out beyond the beyond

It is now widely recognized that car-dependent suburbia hurts public health via an increase in diseases of sedentary lifestyle and due to the stress of spending many hours a week in alternately frenetic and creeping traffic.3 The environmental costs of sprawl include high carbon emissions, impermeable ground covering that rapidly flushes polluted run-off into diminishing areas of creeks and wetlands, and urban heat-island effects from so much concrete and asphalt. Particularly in Ontario, new tracts of car-dependent sprawl can only be built with the sacrifice of increasingly scarce class one farmland.4 Finally, groups such as Strong Towns have documented the long-term fiscal disaster of suburban development.5 Even though higher levels of government typically pay much of the initial cost of major infrastructure, municipalities will be on the hook for maintenance and eventual rebuilding – and property taxes in low-density suburbs seldom bring in enough revenue to cover these steadily accruing liabilities.

Yet in Ontario the large property developer lobby remains as strong a political force as ever. The Premier of Ontario makes no real attempt to hide his allegiance to the largest property developers.6 In Durham Region, after a long public consultation process recommended intensification of existing urban areas to accommodate growing populations, politicians suddenly voted instead for a sprawl-expanding proposal put forward by the development industry lobby.7

So in 2023, corn fields and pastures beyond the current edge of suburbia are being bulldozed, new maze-like streets laid out, thousands of big, cheaply-made, dearly-purchased, cookie-cutter houses stuffed into small lots. For a brief period new residents can look through the construction dust and see nearby farmland or woodland – until the edge of suburbia takes the next step outward.

Suppose you believe, as I do, that this ruinous pattern of development should not and cannot last – that this pattern will not survive past the era of cheap energy, and will not survive when its long-term fiscal non-sustainability results in collapsing services and municipal bankruptcies. When car culture sputters, falters and runs off the road, can these thousands of neighbourhoods, home to millions of people, be transformed so they are no longer car dependent? That’s a big question, but the next post will offer a few ideas.

For today, the edge

How parking ate North American cities

Also published on Resilience

Forty-odd years ago when I moved from a small village to a big city, I got a lesson in urbanism from a cat who loved to roam. Navigating the streets late at night, he moved mostly under parked cars or in their shadows, intently watching and listening before quickly crossing an open lane of pavement. Parked cars helped him avoid many frightening hazards, including the horrible danger of cars that weren’t parked.

The lesson I learned was simple but naïve: the only good car is a parked car.

Yet as Henry Grabar’s new book makes abundantly clear, parking is far from a benign side-effect of car culture.

The consequences of car parking include the atrophy of many inner-city communities; a crisis of affordable housing; environmental damages including but not limited to greenhouse gas emissions; and the continued incentivization of suburban sprawl.

Paved Paradise is published by Penguin Random House, May 9, 2023

Grabar’s book is titled Paved Paradise: How Parking Explains the World. The subtitle is slightly hyperbolic, but Grabar writes that “I have been reporting on cities for more than a decade, and I have never seen another subject that is simultaneously so integral to the way things work and so overlooked.”

He illustrates his theme with stories from across the US, from New York to Los Angeles, from Chicago to Charlotte to Corvallis.

Paved Paradise is as entertaining as it is enlightening, and it should help ensure that parking starts to get the attention it deserves.

Consider these data points:

  • “By square footage, there is more housing for each car in the United States than there is housing for each person.” (page 71; all quotes in this article are from Paved Paradise)
  • “The parking scholar Todd Litman estimates it costs $4,400 to supply parking for each vehicle for a year, with drivers directly contributing just 20 percent of that – mostly in the form of mortgage payments on a home garage.” (p 81)
  • “Many American downtowns, such as Little Rock, Newport News, Buffalo, and Topeka, have more land devoted to parking than to buildings.” (p 75)
  • Parking scholar Donald Shoup estimated that in 1998, “there existed $12,000 in parking for every one of the country’s 208 million cars. Because of depreciation, the average value of each of those vehicles was just $5,500 …. Therefore, Shoup concluded, the parking stock cost twice as much as the actual vehicles themselves. (p 150)

How did American cities come to devote vast amounts of valuable real estate to car storage? Grabar goes back to basics: “Every trip must begin and end with a parking space ….” A driver needs a parking space at home, and another one at work, another one at the grocery store, and another one at the movie theatre. There are six times as many parking spaces in the US as there are cars, and the multiple is much higher in some cities.

This isn’t a crippling problem in sparsely populated areas – but most Americans live or work or shop in relatively crowded areas. As cars became the dominant mode of transportation the “parking problem” became an obsession. It took another 60 or 70 years for many urban planners to reluctantly conclude that the parking problem can not be solved by building more parking spaces.

By the dawn of the twenty-first century parking had eaten American cities. (And though Grabar limits his story to the US, parking has eaten Canadian cities too.)

Grabar found that “Just one in five cities zoned for parking in 1950. By 1970, 95 percent of U.S. cities with over twenty-five thousand people had made the parking spot as legally indispensable as the front door.” (p 69)

The Institute of Transportation Engineers theorized that every building “generated traffic”, and therefore every type of building should be required to provide at least a specified number of parking spaces. So-called “parking minimums” became a standard feature of the urban planning rulebook, with wide-ranging and long-lasting consequences.

Previously common building types could no longer be built in most areas of most American cities:

“Parking requirements helped trigger an extinction-level event for bite-size, infill apartment buildings …; the production of buildings with two to four units fell more than 90 percent between 1971 and 2021.” (p 180)

On a small lot, even if a duplex or quadplex was theoretically permitted, the required parking would eat up too much space or require the construction of unaffordable underground parking.

Commercial construction, too, was inexorably bent to the will of the parking god:

“Fast-food architecture – low-slung, compact structures on huge lots – is really the architecture of parking requirements. Buildings that repel each other like magnets of the same pole.” (p 181)

While suburban development was subsidized through vast expenditures on highways and multi-lane arterial roads, parking minimums were hollowing out urban cores. New retail developments and office complexes moved to urban edges where big tracts of land could be affordably devoted to “free” parking.

Coupled with separated land use rules – keeping workplaces away from residential or retail areas – parking minimums resulted in sprawling development. Fewer Americans lived within safe walking or cycling distance from work, school or stores. Since few people had a good alternative to driving, there needed to be lots of parking. Since new developments needed lots of extra land for that parking, they had to be built further apart – making people even more car-dependent.

As Grabar explains, the almost universal application of parking minimums does not indicate that there is no market for real estate with little or no parking. To the contrary, the combination of high demand and minimal supply means that neighbourhoods offering escape from car-dependency are priced out of reach of most Americans:

“The most expensive places to live in the country were, by and large, densely populated and walkable neighborhoods. If the market was sending a signal for more of anything, it was that.” (p 281)

Is the solution the elimination of minimum parking requirements? In some cases that has succeeded – but reversing a 70- or 80-year-old development pattern has proven more difficult in other areas.

The high cost of free parking

Paved Paradise acknowledges an enormous debt to the work of UCLA professor Donald Shoup. Published in 2005, Shoup’s 773-page book The High Cost of Free Parking continues to make waves.

As Grabar explains, Shoup “rode his bicycle to work each day through the streets of Los Angeles,” and he “had the cutting perspective of an anthropologist in a foreign land.” (p 149)

While Americans get exercised about the high price they occasionally pay for parking, in fact most people park most of the time for “free.” Their parking space is paid for by tax dollars, or by store owners, or by landlords. Most of the cost of parking is shared between those who drive all the time and those who seldom or never use a car.

By Shoup’s calculations, “the annual American subsidy to parking was in the hundreds of billions of dollars.” Whether or not you had a car,

“You paid [for the parking subsidy] in the rent, in the check at the restaurant, in the collection box at church. It was hidden on your receipt from Foot Locker and buried in your local tax bill. You paid for parking with every breath of dirty air, in the flood damage from the rain that ran off the fields of asphalt, in the higher electricity bills from running an air conditioner through the urban heat-island effect, in the vanishing natural land on the outskirts of the city. But you almost never paid for it when you parked your car ….” (p 150)

Shoup’s book hit a nerve. Soon passionate “Shoupistas” were addressing city councils across the country. Some cities moved toward charging market prices for the valuable public real estate devoted to private car storage. Many cities also started to remove parking minimums from zoning codes, and some cities established parking maximums – upper limits on the number of parking spaces a developer was allowed to build.

In some cases the removal of parking minimums has had immediate positive effects. Los Angeles became a pioneer in doing away with parking minimums. A 2010 survey looked at downtown LA projects constructed following the removal of parking requirements. Without exception, Grabar writes, these projects “had constructed fewer parking spaces than would have been required by [the old] law. Developers built what buyers and renters wanted ….” (p 193) Projects which simply wouldn’t have been built under old parking rules came to market, offering buyers and tenants a range of more affordable options.

In other cities, though, the long habit of car-dependency was more tenacious. Grabar writes:

“Starting around 2015, parking minimums began to fall in city after city. But for every downtown LA, where parking-free architecture burst forth, there was another place where changing the law hadn’t changed much at all.” (p 213)

In neighbourhoods with few stores or employment prospects within a walking or cycling radius, and in cities with poor public transit, there remains a weak market for buildings with little or no parking. After generations of heavily subsidized, zoning-incentivized car-dependency,

“There were only so many American neighborhoods that even had the bones to support a car-free life …. Parking minimums were not the only thing standing between the status quo and the revival of vibrant, walkable cities.” (p 214)

There are many strands to car culture: streets that are unsafe for people outside a heavy armoured box; an acute shortage of affordable housing except at the far edges of cities; public transit that is non-existent or so infrequent that it can’t compete with driving; residential neighbourhoods that fail to provide work, shopping, or education opportunities close by. All of these factors, along with the historical provision of heavily subsidized parking, must be changed in tandem if we want safe, affordable, environmentally sustainable cities.

Though it is an exaggeration to say “parking explains the world”, Grabar makes it clear that you can’t explain the world of American cities without looking at parking.

In the meantime, sometimes it works to use parked cars to promote car-free ways of getting around. Grabar writes,

“One of [Janette] Sadik-Khan’s first steps as transportation commissioner was taking a trip to Copenhagen, where she borrowed an idea for New York: use the parked cars to protect the bike riders. By putting the bike lanes between the sidewalk and the parking lane, you had an instant wall between cyclists and speeding traffic. Cycling boomed; injuries fell ….” (p 256)

A street-wise cat I knew forty years ago would have understood.

Lost in traffic: does your time count?

Also published on Resilience

Traffic congestion studies make for quick and easy news articles, but they don’t even begin to calculate the true time lost to car culture.

The news story practically wrote itself: Toronto was ranked 7th worst among world cities for traffic congestion in 2022.

A web search showed similar stories popping up all over: “________________ [nearby city] ranks __th worst in world for traffic congestion.”

What did these traffic congestion ratings really measure? That wasn’t usually spelled out in click-bait articles. But a closer look reveals that the ratings measure and value the time spent by one particular class of urban residents – drivers – while omitting the urban mobility costs born by other citizens.

The basis for the recent round of stories was an annual report by INRIX called 2022 INRIX Global Traffic Scorecard. The company describes their work this way:

“INRIX Research uses INRIX proprietary big data, analytics and industry expertise to understand the movement of people and goods around the world. We achieve this by leveraging billions of anonymous data points every day from a diverse set of sources on all roads in countries of coverage. Our data provides a rich and fertile picture of mobility that enables INRIX Research to produce valuable and actionable insights for policy makers, transport professionals, automakers, and drivers.” (2022 INRIX Global Traffic Scorecard, page 27)

The Traffic Scorecard makes brief mentions of transportation methods such as walking, biking and public transit. But these ways of getting around cities don’t count in the Global Traffic Scorecard – even for cities in which they are the dominant types of mobility.

Instead, the Scorecard tallies and values the time supposedly lost by a particular subset of travelers, which happens to include most policymakers, politicians, the upper ranks of media, and mid- and upper-level businesspeople – that is, those who get around cities routinely by car.

For this class of people, an unobtainable ideal is a key factor in calculating the cost of lost time: the standard of “free-flow conditions.” This is the idea that when a large number of drivers are stalled in slow traffic, each one should imagine how fast they could move if most or all of the other drivers were not on the road; then there would be “free-flow conditions.”

It is nonsensical to imagine that in rush hour in a big city, when most people are commuting all at once, you could ever achieve “free-flow conditions”. Nevertheless this ideal is used as the measuring stick for calculating “time lost in traffic”. As INRIX explains their calculations,

“Total time lost is the difference in travel times experienced during the peak periods compared to free-flow conditions on a per driver basis. In other words it is the difference between driving during commute hours versus driving at night with little traffic.” (p. 10)

Using this standard, INRIX calculates that “The typical US driver lost 51 hours due to congestion in 2022.” In the UK, the typical driver lost 80 hours, and in Germany it was 40 hours.

What is this time “worth”? Using figures from the US Federal Highway Administration, INRIX calculates each hour of time lost in traffic as valued at $16.89 in the US, £8.83 in the U.K., and 10.08€ in Germany. Given the numbers of hours lost by each driver, and the large number of drivers, you can come up with large monetary sums for the cost of congestion. INRIX states that traffic congestion cost the US, for example, $81 billion in 2022. These sums will be bandied about whenever lobbyists advocate for more billions to be spent on road widening projects.

Consider the above excerpt from the INRIX report. The seven “most congested” cities all have substantial, sometimes world-famous public transit systems, and all have a substantial portion of population who don’t own or commute in cars.

How does “traffic congestion” affect all the people who don’t drive but still need to get around? Are they less affected by congestion than those poor, benighted drivers? Or are they even more affected? INRIX doesn’t tell us.

Yet in the number one city for congestion, London, only a minority own a car and a much smaller minority use a car for commuting:

“New census data has revealed that just 20 per cent of Londoners commute by car and 41 per cent of London households have no car at all. Yet despite this relatively low level of car ownership, the city is disproportionately designed to incentivise driving. At nearly 20,000 hectares, 12.4 per cent of land in the capital is taken up by roads – significantly more than the just 8.8 per cent of London currently used for housing.” (Dezeen, “Cities should not just build green transport but actively dismantle car infrastructure”, by Phineas Harper, 11 January 2020)

Statistics are similar for New York City: about 45 percent of households own a car, though fewer use cars to commute. (Source: NYCEDC) Even in Toronto, now dominated by its sprawling suburbs, about 28% of households do not own a car, and in some parts of the city non-car-owners are the majority. (Source: Toronto Star)

Do the non-car-users lose as much time to traffic congestion? For people who live close enough to workplaces or schools to walk or to bike, they might well lose much less time in traffic than the average car commuter (though they may still pay a high price in breathing polluted air, while risking being crushed by cars and trucks on unsafe roads).

But one thing is clear: the time lost by non-car-users is neither counted nor valued in congestion surveys like INRIX’s. And when policymakers make important transportation systems decisions based on surveys like INRIX’s you can expect the results to be seriously flawed.

The Gardiner Expressway walls off Toronto from its waterfront on Lake Ontario, and has required ever more costly repairs. In 2021 the Toronto Star reported “The Gardiner will eat up $2 billion of the 2021-2030 capital plan — 38 per cent of total transportation-related infrastructure spending — meaning the city will spend as much rehabilitating the Gardiner as they will on upkeep on every other roadway.”  But a study commissioned by the Gardiner Coalition found that removing the eastern portion of the expressway could add 5 to 10 minutes to the commute times of rush-hour drivers –  so the elevated expressway is still eating big chunks of the city’s budget.

Arriving at a good estimate of the time non-drivers lose to traffic congestion is difficult, but that doesn’t make the losses any less real. Take, for example, all the time pedestrians spend waiting at traffic lights while autos either speed or crawl through intersections. Think of the extra time pedestrians must spend walking out of their way to get to a relatively safe place to cross a busy road, and then doubling back to their destination. Think of the time public transit users must wait while their packed buses or trams are stalled behind private cars which each carry one person.

The Jane M. Byrne Interchange of expressways I90, I94 and I294, takes a big chunk of downtown Chicago, eating up a lot of time for non-car-drivers who need to get from one side of the tangle to another. Photo by Sea Cow, April 2022, from Wikimedia Commons.

Other lost-time costs of car culture are even harder to calculate. In many cities where car culture has hegemony, large swathes of urban landscape have been cleared and turned into car lanes plus necessary storage space, i.e. parking. That pushes actual destinations – homes, stores, schools, workplaces – farther apart. The resulting greater travel distances cost everyone more travel time. But above all the people who don’t drive, but still need to get around, lose a lot of their time in getting past expressways, multi-lane arterial roads, and parking lots on the way to their destinations. Traffic congestion studies don’t even begin to quantify the time lost to all this “induced distance”.

Studies like INRIX’s scorecard make for quotable listicles and reverse-bragging rights among the driving class. But beware when this skewed data is put forth as a basis for public policy decisions on transportation infrastructure.

Right-sizing delivery vehicles

Cargo bikes can replace far heavier vehicles for a substantial share of urban deliveries. But should you buy a cargo bike for personal use? Probably not.

ALSO PUBLISHED ON RESILIENCE.ORG

In North America we think in extreme terms when it comes to last-mile freight delivery. Whether the cargo is a couple of bags of groceries, a small parcel, a large-screen TV or a small load of lumber, we routinely dispatch vehicles with hundreds-of-horsepower engines.

This practice has never made sense, and there have always been niche markets where some products and parcels have been delivered by bicycle couriers instead of truck drivers. Historically, cargo bikes were in wide use in many cities in the decades before cars and trucks cemented their death grip on most urban traffic lanes.1

Today the cargo bike industry is growing rapidly due to several factors. Many cities are establishing zero-emissions zones. The cost of gasoline and diesel fuel has risen rapidly. Congested traffic means powerful expensive vehicles typically travel at bicycle-speed or slower in downtown areas. Last but not least, the development of low-cost, lightweight electric motors for small vehicles dramatically boosts the freight delivery capacity of e-assist bikes even in hilly cities.

Thousands of companies, from sole-proprietor outfits to multinational corporations, are now integrating cargo bikes into their operations. At the same time there is an explosion of new micro-powered vehicle designs on the market.2

Where a diesel-powered urban delivery van will have an engine with hundreds of horsepower, an electric-assist bike in the EU is limited to a motor of 250 W, or about one-third of one horsepower.3 Yet that small electric motor is enough to help a cyclist make typical parcel deliveries in many urban areas at a faster rate than the diesel van can manage.

A great many other deliveries are made, not by companies, but simply by individuals bringing their own purchases home from stores. In this category, too, North Americans tend to believe an SUV or pick-up truck is the obvious tool for the job. But in many car-clogged cities and suburbs a bicycle, whether electric-assist or not, is a much more appropriate tool for carrying purchases home from the store.

This is an example of a change that can be made at the device level, rapidly, without waiting for system-level changes that will take a good bit longer. When it comes to reducing carbon emissions and reducing overall energy use, the rapid introduction and promotion of cargo bikes as delivery vehicles is an obvious place to make quick progress.

At the same time, the adoption of more appropriate delivery devices will become much more widespread if we simultaneously work on system-level changes. These changes can include establishing more and larger urban zero-emission zones; lowering speed limits for heavy vehicles (cars and trucks) on city streets; and rapid establishment of safe travel lanes for bikes throughout urban areas.

The environmental impact of deliveries

The exponential growth in online shopping over the past twenty years has also led to “the constant rise in the use of light commercial vehicles, despite every effort by cities and regulators to reduce congestion and transport emissions.”4

Last-mile urban delivery, notes the New York Times, “is the most expensive, least efficient and most impactful part of the supply chain.”5

Typical urban parcel delivery trucks have an outsize impact:

“Claudia Adriazola-Steil, acting director of the Urban Mobility Program at the World Resources Institute’s Ross Center for Sustainable Cities, said freight represented 15 percent of the vehicles on the roads in urban areas, but occupied 40 percent of the space. ‘They also emit 50 percent of greenhouse gas emissions and account for 25 percent of fatalities ….’”6

Since vehicle speeds in downtown areas are typically slow, most parcels are not very heavy, and the ability to travel in lanes narrower than a typical truck is a great advantage, a substantial portion of this last-mile delivery can be done by cargo bikes.

Both Fed-Ex and UPS are now building out electric-assist cargo bike fleets in many Western European cities. UPS has also announced plans to test electric-assist cycles in Manhattan.7

How much of the last-mile delivery business can be filled by cargo bikes? A report by the Rapid Transition Alliance says that “In London, it’s estimated that up to 14% of small van journeys in the most congested parts of the city could be made with cargo bikes.”8 City Changer Cargo Bike estimates that in Europe “up to 50% of urban delivery and service trips could be replaced by cargo bikes….”9

It’s important to note that big corporations aren’t the only, or even the major, players in this movement. Small businesses of every sort – ice-cream vendors, bakeries, self-employed carpenters and plumbers, corner grocery stores – are also turning to cargo bikes. The City Changer Cargo Bike report says that “It is important to highlight that the jobs created by cargo bikes are mainly created by Small and Medium-size Enterprises.”10

For small companies or large, the low cost of cargo bikes compared to delivery vans is a compelling factor. The New York Times cites estimates that “financial benefits to businesses range from 70-90% cost savings compared to reliance on delivery vans.”11

The cost savings come not only from the low initial purchase price and low operating costs of cargo bikes, but also from the fact that “electric cargo bikes delivered goods 60 percent faster than vans did in urban centers, and that an electric cargo bike dropped off 10 parcels an hour compared with a van’s six.”12

It’s no wonder the cargo bike industry is experiencing rapid growth. Kevin Mayne of Cycling Industries Europe says sales are growing at 60% per year across the European Union and could reach 2 million cargo bike sales per year by 2030.

Delivery vans in European cities are typically powered by diesel. Replacing a few hundred thousand diesel delivery vans with e-cargo bikes will obviously have a significant positive impact on both urban air quality and carbon emissions.

But what if diesel delivery vans are switched instead to similar-sized electric delivery vans? Does that make the urban delivery business environmentally benign?

Far from it. Electric delivery vans are just as heavy as their diesel counterparts. That means they cause just as much wear and tear on city streets, they pose just as much collision danger to cyclists, pedestrians, and people in smaller vehicles, and they produce just as much toxic tire and brake dust.

Finally, there is the significant impact of mining and manufacturing all that vehicle weight, in terms of upfront carbon emissions and many other environmental ills. There are environmental costs in manufacturing cargo bikes too, of course. But whereas a delivery van represents a large amount of weight for a much smaller delivery payload, a cargo bike is a small amount of weight for a relatively large payload.

In a listing by Merchants Fleet of the “5 Best Electric Cargo Vans for Professionals”, all the vehicles have an empty-weight a good bit higher than the maximum weight of cargo they can carry. (The ratios of empty vehicle weight to maximum cargo weight range from about 1.5 to 3.5.)13

By contrast, a recent list of recommended electric-assist cargo bikes shows that the ratios are flipped: all of these vehicles can carry a lot more cargo than the vehicles themselves weigh, with most in the 4 – 5 times cargo-weight-to-empty-vehicle-weight range.14

One other factor is particularly worthy of note. The lithium which is a key ingredient of current electric-vehicle batteries is difficult, perhaps impossible, to mine and refine in an environmentally benign way. Lithium batteries will be in extremely high demand if we are to “electrify everything” while also ramping up storage of renewably, intermittently generated electricity. Given these constraints, shouldn’t we take care to use lithium batteries in the most efficient ways?

Let’s look at two contrasting examples. An Urban Arrow Cargo bike has a load capacity of 249 kg (550 lbs), and a battery weight of 2.6 kg (5.7 lbs)15 – a payload-to-battery-weight ratio of about 44.

The Arrival H3L3 electric van has a load capacity of 1484 kg (3272 lbs) and its battery is rated at 111 kWh.16 If we assume, generously, that the Arrival’s battery weighs roughly the same as Tesla’s 100 kWh battery, then the battery weight is 625 kg (1377 lbs).17 The Arrival then has a payload-to-battery-weight ratio of about 2.4.

In this set of examples, the e-cargo bike has a payload-to-battery-weight ratio almost 20 times as high as the ratio for the e-cargo van.

Clearly, this ratio is just one of many factors to consider. The typical e-cargo van can carry far heavier loads, at much higher speeds, and with a longer range between charges, than e-cargo bike can manage. But for millions of urban last-mile deliveries, these theoretical advantages of e-cargo vans are of little or no practical value. In congested urban areas where travel speeds are low, daily routes are short, and for deliveries in the 1 – 200 kg weight range, the e-cargo bike can be a perfectly adequate device with a small fraction of the financial and environmental costs of e-cargo vans.

Cargo bikes, or just bikes that carry cargo?

A rapid rollout of cargo bikes in relatively dense urban areas is an obvious step towards sustainability. But should you buy a cargo bike for personal use?

Probably not, in my opinion – though there will be many exceptions. Here is why I think cargo bikes are overkill for an average person.

Most importantly, the bikes most of us have been familiar with for decades are already a very good device for carrying small amounts of cargo, particularly with simple add-ons such as a rack and/or front baskets.

A speed fetish was long promoted by many bike retailers, according to which a “real bike” was as light as possible and was ridden by a MAMIL – Middle-Aged Male In Lycra – who carried nothing heavier than a credit car. Cargo bikes can represent a chance for retailers to swing the pendulum to the opposite extreme, promoting the new category as a necessity for anyone who might want to carry more than a loaf of bread.

In spite of bike-industry biases, countless people have always used their bikes – any bikes – in routine shopping tasks. And with the addition of a sturdy cargo rack and a set of saddlebags, aka panniers, a standard-form bike can easily carry 25 kg or more of groceries. Or hardware, or gardening supplies, or a laptop computer and set of office clothes, or a stack of university textbooks.

The bikes now designed and marketed as cargo bikes can typically carry several times as much weight, to be sure. But how often do you need that capability, and is it worth the considerable downside that comes with cargo bikes?

Cargo bikes are typically a good bit longer and a lot heavier than standard-model bikes. That makes them more complicated to store. You probably won’t be able to carry a big cargo bike up stairs to an apartment, and you might not sleep well if you have to leave an expensive cargo bike locked on the street.

If you only occasionally need to carry larger amounts of cargo, you’re likely to get tired of riding a needlessly heavy and bulky bike the rest of the time.

If you occasionally carry your bike on a bus, train, or on a rack behind a car, a long cargo bike may be difficult or impossible to transport the same way.

Depending on the form factor, you may find a cargo bike doesn’t handle well in spite of its large weight capacity. Long-tail cargo bikes, with an extra-long rack over the rear wheel, can carry a lot of weight when that weight is distributed evenly on both sides of the rack. But if the load is a single heavy object, you may find it difficult to strap the load on the top of the rear rack so that it doesn’t topple bike and rider to one side or the other. (As one who has tried to load a big reclining chair onto a rear rack and ride down the road, I can attest that it’s harder than it sounds.)

The large box style cargo bikes known as bakfiets solve those balance problems, but are typically heavy, long, and thus difficult to store. They can be ideal for moving around a city with children, though many parents will not feel comfortable doing so unless there is a great network of safe streets and protected bike lanes.

For people who have a secure storage space such as a garage, and the budget to own more than one bike, and for whom it will often be helpful to be able to carry loads of 100 kg or more by bike – a cargo bike might be a great buy. Or, perhaps a cargo trailer will be more practical, since it can add great cargo-carrying ability to an ordinary bike on an as-needed basis.18

Ideally, though, every urban area will soon have a good range of cargo-bike businesses, and some of those businesses will rent or loan cargo bikes to the rest of us who just occasionally need that extra capacity.

In the next installment of this series on transportation, we’ll look at a sector in which no significant device-level fixes are on the horizon.

The high cost of speed

Also published on Resilience

Imagine that we used a really crazy method to establish speed limits. We could start by recording the speeds of all drivers on a given stretch of roadway. Then, without any clear evidence of what a safe speed might be, we might argue that the great majority of people drive too fast, and therefore the maximum legal speed will be set as that speed exceeded by 85 percent of drivers. Only the slowest 15 percent of drivers, in this scenario, would be considered to be driving within the legal limit.

If you have a passing familiarity with the legal framework of car culture, you will recognize the above as a simple inversion of the common 85th percentile rule used by traffic engineers throughout North America. Following this guideline, driver speeds are recorded, engineers determine the speed exceeded by only 15 per cent of the drivers, and that speed is deemed an appropriate speed limit for the given roadway. All the other drivers – 85 per cent – will then be driving within the speed limit.

Two recent books argue that the 85th percentile guideline is as arbitrary and misguided as it sounds. In There Are No Accidents, (Simon & Schuster, 2022; reviewed here last week), Jessie Singer summarizes the 85th percentile rule this way:

“Most speed limits are not based on physics or crash test expertise but simply the upper limit of what most amateur drivers feel is safe. A speed limit is the perceived safe speed of a road, not the actual risk of traveling that speed on that road.” (Singer, page 95)

Singer draws on the work of Eric Dumbaugh, who has a PhD in civil engineering and teaches urban planning at Florida Atlantic University. Dumbaugh has analyzed tens of thousands of traffic crashes in urban environments in the US. He concluded that the traffic engineering guidelines used for decades are based on false information, are often misapplied, and result in dangerous conditions on urban roadways. Absent physical evidence of what constitutes a safe driving speed, engineers simply assume that most drivers drive at a safe speed. Dumbaugh doesn’t mince words:

“Traffic engineering is a fraud discipline. It presumes knowledge on road safety that it doesn’t have and it educates people generation after generation on information that is incorrect.” (quoted by Singer, page 96)

The dangerous conditions on roadways have contributed to thirty thousand or more deaths in the US every year since 1946. But the engineers who design the roadways cannot be faulted, so long as they have applied the rules passed down to them in standard traffic engineering manuals.

Confessions of a Recovering Engineer was published by Wiley in 2021.

Similar themes are also a major focus in an excellent book by Charles Marohn Jr., Confessions of a Recovering Engineer (Wiley, 2021). Marohn was trained as a civil engineer, and for the first part of his career he worked as a traffic engineer designing what he saw at the time as “improvements” to roadways in small cities. Over time he began to question the ideas he had absorbed in his education and the guidelines that he followed in his engineering practice.

Marohn is now founder and president of Strong Towns. He has emerged as one of the most vociferous critics of the planning principles underlying American suburbia, and the design guidelines used to justify the arterial roads in those suburbs. He writes,

“The injuries and deaths, the destruction of wealth and stagnating of neighborhoods, the unfathomable backlog of maintenance costs with which most American cities struggle, are all a byproduct of the values at the heart of traffic engineering.” (Marohn, page 5)

These values are held so widely and deeply, Marohn says, that they are seldom questioned or even acknowledged. These values include :

“• Faster speeds are better than slower speeds..
• Access to distant locations by automobile is more important than access to local destinations by walking or biking. …
• At intersections, minimizing delay for automobile traffic is more important than minimizing delay for people walking or biking.” (Marohn, page 12)

Working from his own experience as a traffic engineer, Marohn explains the order in which issues are considered when designing a new or “improved” roadway. First the engineer decides on a “design speed” – a driving speed which the road should facilitate. Next to be established is the traffic volume – all the traffic typically traveling the route at present, plus all the additional traffic the engineer anticipates in the future. At that point the engineer will choose a design based on official guidelines for that design speed and that traffic volume; so long as the guidelines are followed, the design will be deemed “safe”. Finally, the engineer will estimate how much it will cost.

Marohn argues that the questions of whether traffic should move slow or fast, and whether all existing traffic should be accommodated or instead should be restricted, are not technical issues – they are questions of values, questions of public policy. Therefore, he says, issues of the desired traffic speed and desired traffic volume should be dealt with through the democratic process, with public input and with the decisions made by elected officials, not by engineering staff.

Some sins are forgiven

In the early days of car culture, traffic casualties happened at a far higher rate per passenger mile than they do in recent decades. Part of the improvement is due to changes in vehicle design – padded surfaces, seat belts, air bags. Part of the improvement can be attributed to what is called “forgiving design”, at least as applied on rural highways. Examples of forgiving design are gradually sloped embankments, which reduce the likelihood of rollovers if a driver veers off the road; wider lanes which lessen the chance of sideswiping; centre barriers which prevent head-on collisions; straightening of curves to improve sightlines; and removal of roadside obstacles such as large trees which an errant driver might hit.

On highways these forgiving design principles make sense, Marohn believes, but on urban arterial roads they are disastrous. He coined the word “stroad” for urban routes that combine the traffic complexity of streets with the high design speeds of inter-city roads. Stroads feature the wide lanes, cleared sightlines and levelized topography of highways, giving drivers the impression that higher speeds are safe. But stroads also have many intersections, turning vehicles, and access points for pedestrians. This means that the higher speeds are not safe, even for the drivers. And vulnerable road users – pedestrians and cyclists – often pay with their lives.

Most stroads should be converted into streets, Marohn says. “Instead of providing drivers with an illusion of safety, designers should ensure the drivers on a street feel uncomfortable when traveling at speeds that are unsafe.” (Marohn, page 43) To ensure that the mistakes of pedestrians and cyclists, and not just drivers, are forgiven, he advocates these guidelines: “Instead of widening lanes, we narrow them. Instead of smoothing curves, we tighten them. Instead of providing clear zones, we create edge friction. Instead of a design speed, we establish a target maximum travel speed.” (Marohn, page 41)

On a typical urban street, with stores, offices, schools, restaurants, and many people moving around outside of cars, that target maximum speed should be low: “Traffic needs to flow at a neighborhood speed (15 mph [24 kph] or less is optimum) to make a human habitat that is safe and productive.” (Marohn, page 56)

In recent years there has been a substantial rise in pedestrian and cyclist fatalities, even as motorist fatalities have continued a long downward trend. The rising death toll among vulnerable road users was particularly noticeable during and following the pandemic. In Marohn’s words we find a good explanation:

“Most [traffic fatalities] happen at nonpeak times and in noncongested areas. … the traffic fatality rate is much higher during periods of low congestion. This is … because the transportation system is designed to be really dangerous, and traffic congestion, along with the slow speeds that result, is masking just how dangerous it is.” (Marohn, 117)

With many businesses closed and many people working from home, there was much less traffic congestion. And without congestion acting as a brake, people drove faster and more pedestrians were killed. That wasn’t intentional, but it was predictable – it was no accident.

* * *

As Jessie Singer explains, we find an extensive matrix of causes that contributes to “accidents” when we look beyond the individual making a mistake. That matrix very often includes racial and economic inequality, which is why poor people suffer more in nearly every accident category than rich people do.

Both racial and economic factors come into play in the current wave of pedestrian deaths. In the major city closest to me, Toronto, pedestrian deaths occur disproportionately among racialized, poor, and elderly people. These deaths also occur most often on wide arterial roads – stroads – in older suburbs.

Marohn’s words again are enlightening: “as auto-oriented suburbs age and decline … they are becoming home to an increasing number of poor families, including many who do not own automobiles.” (Marohn, page 43) When these residents need to walk across four, five or six lane high-speed arterial roads, the predictable result is pedestrian deaths among the most vulnerable. An obvious, though politically difficult, solution is to redesign these roads to bring speeds down to a safe level.

The inequality that contributes to “accidents” is buttressed in most North American cities by an elaborate legal framework telling people where they are allowed to live and work. That legal framework is zoning. In the next installment of this discussion we’ll look at the history and consequences of zoning.

‘Zero crashes, zero congestion, zero emissions’ – the perennial myths of autonomous vehicles

Also posted on Resilience.

For a hundred years the auto industry has held out visions of a trouble-free future for drive-everywhere society – and that future is always about 20 years away. Peter Norton urges us to see the current hype about automated vehicles in the cold light of the failed promises of the past.

American automakers had a problem in the 1920s. Cars were selling well in rural areas, but in the cities – home of a steadily growing share of the population – cars were meeting a lot of resistance.

Autonorama, by Peter Norton, is published by Island Press, October 2021.

Parking was scarce, streets were full of people, drivers usually had to go slow – and they still managed to kill a shocking number of pedestrians. Cars weren’t very convenient in cities, and there was so much public outrage over killings that many cities were considering severe restrictions on car use.

The response, Peter Norton writes in Autonorama, came from the coalition of automakers, car dealers, drivers, oil companies, and road builders he refers to as “motordom”. Their strategy had both long-term and short-term prongs. First, it was necessary to win public acceptance of the radical idea that city streets should be generally cleared of pedestrians so that cars could routinely drive faster. Second, local, state and federal governments had to be persuaded to invest millions, and soon billions, in widening streets and in building entirely new highways, not only between cities but within cities.

These long-term efforts, however, wouldn’t keep sales up in the short term. As Norton explains,

“No matter what the expenditure on roads and highways, in no given year could it deliver marked improvement. What was needed was a clear vision of a more distant and idealized future toward which motordom was striving. The promise of future perfection can buy tolerance of present affliction.” (Autonorama, from Island Press, October 2021, page 29)

To present this “clear vision of an idealized future”, motordom turned to creative minds in advertising, theater and film-making. During the 1930s, GM, Ford and Shell sponsored increasingly elaborate presentations of future cities where everyone drove, everywhere, without a hint of traffic congestion, and in perfect safety. The process culminated in Futurama, by far the most popular exhibit at the 1939 New York World’s Fair. In Norton’s view, the Futurama template has been revived periodically by motordom ever since. “Autonorama”, the heavily hyped story that “autonomous vehicles” will soon take over our roads, while ending crashes, congestion and emissions, is the latest iteration of a marketing fantasy now several generations old.

By the late 1950’s, one element of the strategy had been largely accomplished: new standards in traffic engineering had enforced auto dominance on streets, and had defined any delay to drivers – caused, of course, by all the other drivers – as an unacceptable cost to all society which should be remedied by public expenditure on roadways. A second strategic element – a vast new highway-building project – had been approved and was under construction.

Yet traffic congestion grew as rapidly as the number of cars on the roads and streets, as did the numbers of crash casualties. It was time for a new round of Futurama, and motordom answered the call with language that remains familiar all these years later.

“Automobile accidents will be eliminated completely”

In a 1958 episode of Disneyland sponsored by the Portland Cement Association, the narrator intones,

“As Father chooses the route in advance on a push-button selector, electronics take over complete control. Progress can be accurately checked on a synchronized scanning map. With no driving responsibility, the family relaxes together. En route, business conferences are conducted by television.” (quoted in Autonorama, page 51)

The specifics of how the nascent electronics industry might accomplish these wonders had to be left to the imagination. No matter. A 1961 Pennsylvania ad campaign assured readers that “the nation’s finest automotive and scientific brains … predict that someday in the future automobile accidents will be eliminated completely.” If that blissful fantasy remained distant, it was not for lack of industry effort. Technology companies, auto makers, and government transportation departments teamed up to construct automated car test tracks in locations around the US. The vision received its most elaborate portrayal in GM’s Futurama 2, the biggest pavilion at the 1964-65 New York World’s Fair.

To the extent that newly widened arterial roads were engineered for greater speed, they also became more deadly for all users, including the fewer and fewer remaining pedestrians. And to the extent that officially favored development patterns induced people to live farther away from work, schools and shopping, even more people became car-dependent and the roads filled with congestion as fast as they were built.

As Norton explains, American cars were and remain the least spatially efficient mode of transportation in common use. It never made sense to think that by putting each driver/passenger in a steel box that takes 10 square meters of road space, we would vanquish the problem of roadway congestion. Though a congestion-free car culture could never be achieved, it remained essential for motordom to keep painting the pretty picture – all to keep consumers buying new cars every few years, and to keep politicians authorizing greater public works expenditures.

The road-building boom begun in the 1950s, with “the biggest public works project in history” justified primarily for its supposed traffic congestion benefits. But “Four decades and $100 billion later, GM was claiming that congestion was worse than ever, and getting worse still.” (Autonorama, page 93) The congestion was cited to promote a new round of public spending in what Norton terms “Futurama 3”. Reflecting public concern about the deadly effects of air pollution, the visions also started to promise the elimination of harmful emissions.

In the 1990s the new focus was on “Intelligent Highway-Vehicle Systems”. A decade of work yielded one viable congestion-reducing technology – but it was not a technology the auto industry could support. Electronics had advanced to the point where it was clearly workable to automatically charge road tolls at times of peak use, or within perennially congested areas such as urban cores. Although congestion pricing has now been used to great success in Europe, the practice does not encourage people to buy more cars, and so it was not a strategy American motordom embraced.

The latest and current flourish of car culture futurism is what Norton terms “Autonorama.” Over the past two decades, the emphasis has shifted from “smart highways” to “smart cars,” with a promise that smart cars will soon safely drive themselves everywhere, from the wide-open road to city streets teeming with cars, buses, bicyclists and pedestrians. And today, Norton adds, autonomous vehicle boosters want to sell not just new cars and new roads, but also new data.

“Social media on wheels”

If you’re one of the tens of millions who start and end each workday with a long, stressful drive, you might not even be aware of one of the major downsides in driving. A 2016 report from consultants McKinsey & Co. highlighted “the greatest single constraint on personal data collection besides sleep: the attentional demands of driving.” There’s the problem: while you are driving you can’t give your full attention to social media!

And that’s no joke, to the huge industry of data collectors and brokers. Time spent looking at the road is time wasted – because while you’re driving, the data hounds are unable to learn much about your likes, dislikes, what you believe, what you watch, what you share, and what you are likely to buy.

In an insightful chapter titled “Data Don’t Drive,” Norton cautions us to think carefully about the business catch-phrase “data-driven.” Data might guide decisions, but data don’t drive decisions – people do. People make decisions through judgment calls, both about the meaning of data, and about which data matter and which data don’t matter.

Where profit-focused industries are concerned, it is not data that matter but monetized data or at least monetizable data. The engines of consumerism are stoked by data from and about people who can spend money, and preferably lots of it. Which data is likely to be worth more: an hour’s worth of smart-phone data from a person standing in the cold waiting for a bus? Or an hour’s data from the in-car digital entertainment system in a state-of-the-art new automated car?

This in-built tendency to reinforce social inequality is at the heart of Norton’s concerns, not only with Autonorama but with the whole history of auto-centered planning. It’s not just that vast sums of public money have been devoted to infrastructure that never comes close to the promise of “no congestion, no crashes.” It’s also that in focusing attention over and over on the needs and wishes of motordom, the needs of those who can’t or won’t drive are systematically downplayed. In the process, industry and government fail dismally to preserve or create safe, efficient, pleasant, healthful, walkable urban environments. The modest expenditures that would make cities safe for non-drivers are declined, while hundreds of billions are spent instead on transport “improvements” that continue to produce more deaths, more congestion, and more pollution.

Norton writes that

“The twentieth century should have taught us that accommodation of expensive transport does not merely neglect affordable mobility; it actively degrades it.” (Autonorama, page 180)

Two decades into the 21st-century, we should heed Norton’s warnings about Autonorama, turn our backs on car culture, and begin the rewarding task of reclaiming urban space for efficient public transit, safe cycling, and healthy and stress-free walking.

Healthy, peaceful and more equitable – life in the low-car city

Also published on Resilience

“For as long as humans have been living in cities, and until only recently, streets were the main site where children grew up,” write Melissa Bruntlett and Chris Bruntlett, in the opening pages of their new book Curbing Traffic: The Human Case for Fewer Cars in Our Lives. 

Curbing Traffic is published by Island Press, June 2021.

Unfortunately city streets in the twentieth century became unsafe spaces for humans, especially young humans, when so much prime urban real estate was ceded over to cars. The Bruntletts discuss the negative effects of car culture for children, for care-givers, for social cohesion, for social justice, for mental health, for the ability of the elderly to age in place – plus the positive effects in these realms when urban planners carefully and sensibly curb traffic.

In a previous book, Building The Cycling City: The Dutch Blueprint for Urban Vitality (reviewed here), the Bruntletts described the policies and practices that have transformed cities throughout the Netherlands and have turned the nation into a world leader for active transportation. Their new book deepens the analysis from a distinctive personal perspective: two years ago the couple and their two children moved from Vancouver, British Columbia to the Dutch city of Delft.

Visitors to the Netherlands are rightly amazed at the extensive network of dedicated bike lanes which go to every section of every city, as well as through the countryside. But just as importantly, the Bruntletts explain, is how the Dutch deal with myriad residential streets that do not have dedicated bike lanes: these streets must be safe for human interaction, whether that means kids playing games or biking to school, neighbours standing and chatting, elders strolling along while admiring gardens.

“The Dutch Blueprint for Urban Vitality” isn’t really about bicycles. It’s about refusing to sacrifice vast amounts of the public realm to the private automobile; instead reserving space for commerce, community, and social connection. The ubiquitous bicycles are simply a by-product of that larger process; a tool to achieve the end goal of what policy makers call an autoluw (low-car or nearly car-free) city.” (Curbing Traffic, page 4)

Where Building the Cycling City focused on the freedom to bike safely, Curbing Traffic pays more attention to the benefits of a low-car city for those who are not, at any given time, on bikes.

The Child-Friendly City

It starts with children.

Historians of the cycling revolution in the Netherlands cite the key role of the “stop de kindermoord” – stop the child-murders – protest movement nearly fifty years ago. Alarmed and outraged by the ongoing tragedy of children being struck down by motorists, Dutch citizens began what would become a far-ranging reclamation of street space.

Fittingly, the first chapter of Curbing Traffic is entitled “The Child-Friendly City”. Prior to the automobile era, the Bruntletts write, urban children could take care of themselves for hours every day, playing on the street close to home within sight of a parent or trusted neighbours.

The dominance of cars turned that safe space into a violent space. In the words of University of Amsterdam geographer Dr. Lia Karsten, in most cities “cars occupy the street and the space in front of the house. What we see is parents are more afraid because of the danger of motorized traffic. This danger is directly in front of the house, which should be one of the safest places for children.”

Making residential streets safe again for children has involved a complex of modified street  design, driver-responsibility laws, and strong social norms that tell drivers they are guests on these streets. Dutch streets have become, once again, places for socializing for people of all ages. And because the safe space starts right outside most urbanites’ front doors, children can take off on their own to bike to school, to sports fields, libraries and stores.

The success of the famous Dutch cycling lane network, then, depends on people of all ages being able to safely navigate their neighbourhood streets before reaching the cycle lanes along major roads.

Care is essential

Child care is one important type of care work, and the freedom to let children play outside on safe streets is itself liberating for child-caregivers, who tend to be women. That is one advantage a low-car city has in becoming a feminist city, but there is more.

Curbing Traffic notes that historically the traffic planning profession has considered “work” to mean paid work, which in turn has emphasized commuting to full-time jobs away from home. Planners have focused on facilitating these longer-distance commuting trips, which happen once at the beginning of the work day and once at the end.

Care-givers, on the other hand, typically engage in many shorter trips – to a day-care centre, grocery store, or children’s after-school activities. These trips, which often add up to more kilometres per day than a bread-winner’s commuting, are ignored in many traffic planning studies. (“The Canadian census, for example, only asks about journey to work data, as do countless other countries,” the Bruntletts write.) When these trips are made by a care-giver who also works a paid job, they often involve detours on the trip to or from a paid workplace – “trip-chaining.”

Even in cities which are now putting significant resources into cycling infrastructure, the focus is often on the type of major-thoroughfare bike lanes used by bike commuters to get far beyond their own neighbourhood. (As an example, the Bruntletts discuss new cycling infrastructure in their former home city, Vancouver. See also my discussion of the “cycle super-highways” in London, UK, here.)

In most Dutch cities, by contrast, many short trips that go along with care work happen on streets that are just as quiet, relaxed and safe as the dedicated cycle lanes are. That is one important reason that in the Netherlands, in strong contrast to most industrialized nations, the urban cycling population is more than half women.

Car noise makes us sick

The air pollution caused by motor traffic is frequently discussed, for good reason. Less understood, the Bruntletts write, is the pervasive effective of noise pollution caused by motor traffic:

“While air and water pollution tend to receive the most attention from environmentalists, noise is, in fact, the pollutant that disturbs the greatest number of people in their daily lives. It is a universal stressor, one that stimulates the fight-or-flight response in virtually all animals. An astonishing 65 percent, or 450 million Europeans reside in dwellings exposed to levels above 55 decibels, the amount the World Health Organization (WHO) deems unacceptable.” (Curbing Traffic, page 92-93)

The noise falls into two primary categories, propulsion noise and rolling noise. The arrival of electric vehicles, with their silent engines, should significantly reduce propulsion noise. Rolling noise – caused by the friction of tires on surfaces – goes up dramatically with vehicle speed, and is not ameliorated by electric motors. Unfortunately, Curbing Traffic notes, rolling noise is trending worse, “as the automobile industry continues to push out larger and heavier vehicles, which also require wider tires.”

Constant motor traffic noise, which reminds our senses that streets are dangerous places, stimulates a flow of “fight-or-flight” hormones and contributes to stress. This happens whether or not we are “used to the noise.” In the words of Dr. Edda Bild, a soundscape researcher at McGill University, “People who live in big cities are used to the churning sounds of passing cars. But just because we don’t perceive it, doesn’t mean our body isn’t having a physiological response to what’s happening.” As with air pollution, noise pollution tends to be worst in low-income and otherwise disadvantaged neighbourhoods.

The ill health effects associated with the pervasive presence of noisy, dangerous vehicles go beyond the physical to the mental. Canadian neuroscientist Robin Mazumder summarizes what urban planners can do to help address the global mental health crisis: “Primarily, we need to eliminate the threat that cars pose. Whether that’s through traffic calming or car-free streets, that’s the first thing I would target.”

Through reflections on their personal experiences and through discussions of the work of diverse urban life researchers, the Bruntletts cover far more  issues than this review can touch on. Curbing Traffic is both entertaining and deeply thought-provoking. Let’s give them the last word.

Living in Delft, they write, has shown them “what is possible when we reduce the supremacy of motor vehicles from our lives and prioritize the human experience.” They add,

“With the right leadership, traffic evaporation policies, as well as those aimed at improving social connection, reducing noise, addressing mental health and equity, and ensuring resiliency regardless of what environmental and health challenges are yet to come, cities of all sizes can provide the quality of life our family now cherishes. We understand why it is so important to have fewer cars in our lives. The critical next step starts today. Now is the time to make it happen.” (Curbing Traffic, page 218)

Make room for the bus

A review of Better Buses, Better Cities

Also published at Resilience.org

Better Buses, Better Cities, by Steven Higashide, published by Island Press and University of British Columbia Press, October 2019

We often hear that “the greenest building is the one you already have.” The idea is that the up-front carbon emissions released during the production of a new building can outweigh many  years of emissions from the old building. So in many cases retrofitting an old building makes more environmental sense than replacing it with a new “state-of-the-art” facility.

But should we say “the greenest transportation infrastructure is the one we already have?” Yes, in the sense that by far our biggest transportation infrastructure item is our network of paved roads. And rather than rushing to construct a new infrastructure – with all the up-front carbon emissions that would entail – we should simply stop squandering most of our road lanes on the least efficient mode of transportation, the private car.

While new light-rail systems, subways, inter-urban commuter trains all have their place, simply giving buses preference on existing roads could improve urban quality of life while bringing carbon emissions down – long before the planning and approval process for new train lines is complete.

Steven Higashide’s new book Better Buses, Better Cities is a superb how-to manual for urban activists and urban policy-makers. The book is filled with examples from transit reforms throughout the United States, but its relevance extends to countries like Canada whose city streets are similarly choked with creeping cars.

Given the book’s title, it is ironic that few of these reforms involve improvements to the bus vehicle itself (though the gradual replacement of diesel buses with electric buses is an important next step). Instead the key steps have to do with scheduling, prioritizing the movement of buses on city streets, and improving the environment for transit users before and after their bus rides.

Higashide begins the book by noting that buses can make far more effective space of busy roads:

Add bus service to a road and you can easily double the number of people it carries – even more so if buses are given dedicated space on the street or if a train runs down it. When you see a photograph of a bus in city traffic, there’s a decent chance that the bus is carrying more people than all the cars in the same frame.” (Better Buses, Better Cities, page 3)

Buses move more people than cars even on congested streets, but the people-moving power of a street really soars if there is adequate dedicated space for pedestrians, cyclists and transit users:

From Better Buses, Better Cities, by Steven Higashide, page 3

Frequency equals freedom

Which comes first – a bus route with several buses each hour or a bus route with big ridership? Municipal politicians and bean counters often argue that it makes no sense to up the frequency of lines with low ridership. But many surveys, and the experience in many cities, show that potential riders are unlikely to switch from cars to buses if the bus service is infrequent. In Higashide’s words,

The difference between a bus that runs every half hour and a bus that runs every 15 minutes is the difference between planning your life around a schedule and the freedom to show up and leave when you want.” (Better Buses, p. 23)

There is thus an inherent tension between planning routes for frequency, and planning routes for maximum coverage. The compromise is never perfect. A small number of high-frequency routes might get high ridership – as long as the major destinations for a sufficient number of riders are easily accessible. A route map with meandering service through every area of a city will provide maximum coverage – but if service is infrequent and slow, few people will use it.

In any case, overall bus network plans must be updated periodically to reflect major changes in cities, and Higashide provides case studies of cities in which transit restructuring was accomplished with very good results in a short time period.

Still, adding several buses each hour doesn’t help much if the streets are highly congested. Instead the result might be “bunching”: a would-be rider waits for a half hour, only to then have three buses arriving in a row with the first two packed full.

He emphasizes that “making buses better can start with redrawing a map, but it has to continue by redesigning the street.” (Better Buses, p. 37)

To emphasize the point he cites declining average speeds in most US cities since 2012, with New York City buses crawling at 7.6 mph in 2016. “Among the culprits,” Higashide writes, “is the enormous increase in Uber and Lyft rides; Amazon and other retailers have also led to a doubling in urban freight traffic associated with online shopping.” (Better Buses, p. 44)

Effectively restricting some lanes to buses is one strategy to make transit use an  attractive option while making better use of road space. Others are the introduction of advance traffic signals for buses, or “bump-out” bus stops that allow buses to travel in a straight line, rather than swerving right to pick up passengers and then waiting for a chance to move back out into the traffic.

Transit planners often overlook the pedestrian experience as something that’s out of their realm, Higashide says. But a large majority of bus users walk to the bus, and then walk from the bus to their destination.

Unfortunately the dominance of autos in American cities has resulted in streets that are noisy, polluted, frightening and unsafe for pedestrians. In addition transit stops often have no shelter from scorching sun, cold wind or rain, and transit-using pedestrians may have very good reason to feel unsafe while they wait for a bus or while walking to or from the bus. Higashide gives welcome attention to these issues.

Finally, he discusses the rapid progress made by activists in cities where “pop-up” projects have introduced ideas such as dedicated bus lanes. Transit agencies, he says, “have to discard ponderous project development processes that result in 5-year timelines for bus lane projects and try tactical approaches that change streets overnight instead.” (Better Buses, page 11)

The people most likely to need better bus services are least likely to sit through years of public consultations. But pilot projects on specific street sections can demonstrate the many benefits of bus prioritization – for transit users, pedestrians, cyclists, car drivers and businesses alike. Higashide discusses pop-up projects which have been introduced in weeks instead of months or years, and have proven effective so quickly that they were adopted and expanded.

That’s good news for city dwellers, and good news for the rest of us too. With such an urgent need to cut carbon emissions, fast, we can not afford to spend ten or fifteen years waiting for huge new transit infrastructures. Likewise we shouldn’t put our hopes in a vast new fleet of electric cars, which will clog streets just as thoroughly as internal combustion cars do today.

In his conclusion, Higashide turns his focus directly to both the social justice and carbon emission implications of transit choices. Speaking of Green New Deal policies, he says “what they choose not to fund is as important as what they do fund.”

Federal policy must make it harder to build new roads, recognizing that highways are fossil fuel infrastructure as surely as oil and gas pipelines are and that their construction often directly harms neighborhoods where black and brown people live, so that suburban residents can get a faster trip.” (Better Buses, page 128)

We don’t need more lanes of pavement. We need to make room for buses on the pavement we already have.

A tale of three cities – cycling in Valencia, Paris and London

Also published at Resilience.org

Efforts to promote cycling are gathering steam in many cities for a wide variety of reasons. Campaigns may fly the banners of carbon emissions reductions, reducing air pollution for immediate health reasons, promotion of active lifestyles to combat obesity, creation of safer streets for non-auto-driving residents as a social justice issue, reduction of inefficient private-car usage as a way to fight gridlock – or all of the above.

On a recent trip to western Europe I had the chance to compare results of these campaigns so far.

The gold standard on a nationwide level, of course, is set by the Netherlands, the subject of the first two installments in this series (here and here). The Dutch have been working on this in a concerted way for forty years, and they are far ahead of the other countries I visited. Though I haven’t been to Denmark, my observations here are also shaped by the excellent book Copenhagenize, and addresses by that book’s author, Mikael Colville-Andersen, at two conferences I’ve had the good fortune to attend.

I was able to cycle about 100 kilometers each in Valencia and Paris, and 150 kilometers in London. But these are big cities and my rides weren’t nearly enough to cover all areas. My observations are also based on a single visit, so I’m not trying to write any sort of “report card” on how successful these cities’ recent programs have been.

Yet in observing which efforts are working well so far, which are showing promise, and which ones seem seriously flawed, I hope these reflections are of use to people in many other cities. Although our geographic and political situations vary a great deal, nearly all cities in industrial civilization have been dominated by car culture for a few generations, and we face many common challenges as we work back towards cities that are safe for everyone who could and should be moving about our streets.

Stealing bike lane space from pedestrian sidewalks

In both Valencia and Paris, I was immediately struck by the extensive use of paint-on-pavement to signal that “bikes belong here”. Any recognition of the rights of cyclists is a welcome first step. But in both cities, there were prominent examples of “cycle lanes” that did little or nothing to make streets either safe or convenient for cyclists, and instead were setting up more conflict between pedestrians and cyclists.

The core of Valencia has many wide arteries with relatively wide sidewalks as well as multiple lanes given to cars. Rather than carve some space out of the street for a protected bike lane (e.g., by eliminating a car lane, narrowing all car lanes slightly, or taking away some car parking space), planners have instead painted a bike lane on the already well-used pedestrian sidewalk.

This is quick and cheap and risks less pushback from the motorists’ lobby. But it results in terrible bike lanes, which wind and curve around light poles and bus shelters, and force cyclists to merge with pedestrians as they cross intersections and then sort themselves into separate areas on the sidewalk when they get to the other side. The pedestrians, quite naturally, amble into the painted bike lane frequently; many of them no doubt have strolled the same sidewalks for decades, and find it difficult and more than a little annoying to now keep in mind that cyclists might be whizzing by in what used to be a safe space for distracted walking.

Cycling these areas, then, is only slightly faster than walking – and cycling to work would not be an attractive option for most people with a commute of more than a kilometer or two.

Outside of the oldest central core of Valencia (where streets are very narrow and quiet) many side streets are just big enough for three car lanes plus narrow pedestrian sidewalks. Planners have so far chosen to make many of these streets one-way, with car parking on both sides. This leaves no room for a bike lane and guarantees slow movement for everybody, whether in car or on bike or on foot.

The obviously necessary  – but obviously politically challenging – course would be to take some street space back from cars and allocate it to cyclists, while preserving sidewalk space for pedestrians. This would make both walking and biking more pleasant and safe, and would promote a gradual shift to active transportation rather than reinforcing car culture.

In Paris I saw the same timid steps to create bike lanes on busy arteries without taking away any space from cars, with similar results. The wide Boulevard de Rochechouart and Boulevard de Clichy, near the train station Gare du Nord, both feature six or more lanes devoted to cars, plus a wide park-like median for pedestrians.

With such an expansive street allowance bequeathed to them by citizens from previous centuries, could planners find a sensible way to allocate a few meters for a protected bike lane? Alas, the car space has apparently been deemed sacrosanct, and bike lanes have been painted through the formerly pedestrian-only medians. Because of many obstructions in these medians, the bike lanes shift positions frequently – on one block there may be two uni-directional lanes at the outside edges of the median, while on the next there is a bi-directional bike lane in the center of the median.

Not surprisingly pedestrians wander across the bike lanes or stand there chatting or checking their phones, and the angry ringing of bike bells and the squeak of bike brakes adds new notes to the chorus of car horns. Cyclists unfamiliar with the routing must also find the shifting cycle lane after crossing each intersection, and that can be difficult to do while also dodging cars, taxis and delivery trucks. For a bicycling tourist the whole scene may be quaintly amusing, but it would not make for a pleasant or convenient ride on any regular basis.

Routes through recreational areas

Both Valencia and Paris do have new features that make cycling a very enjoyable, calm and safe activity in particular recreational or scenic areas. This doesn’t do a lot to encourage residents to take up biking for daily commutes, but it does help make the city a more attractive place in leisure hours.

A striking feature in Valencia is the major linear park through the heart of the city, occupying the shallow valley of the Turia River which was diverted in 1969. This park is now widely used by cyclists of all ages, who travel through the park to the spectacular Ciutat de les Arts i les Ciències and other attractions.

Spacious paths for cycling and walking wind through the Turia River valley (above and below). Largely free from motor traffic, these areas offer safe recreational cycling for people of all ages, within a few blocks of dense urban districts.

On the sparsely populated south-east flank of the city, there are also some excellent cycle routes connecting the core city with the port district.

In Paris a new initiative has been both warmly welcomed and hotly contested. In 2016, city council approved the banning of motor vehicle traffic on a formerly busy, 3.3 kilometer roadway on the “right bank” of the River Seine. (A similar roadway was closed to motor traffic along the left bank of the Seine in 2013.)

This roadway (shown in the photo at the top of this article) provides great views of and access to many of the city’s most famous sights. Popular with walkers, runners and cyclists, the spacious route has also proven an immediate hit for people taking advantage of the new dockless scooters.

Coincidentally, while I was in Paris a court decision upheld the closure of these roads to cars, allowing the city to do much more to make these important areas attractive for active, healthy and non-polluting transport.

High-profile initiatives like the Seine roadway transformation will have little direct impact on daily transportation of most Parisians, beyond those who live or work very close to these routes. To be truly effective, a good bike route network needs to connect most residents safely to most of the destinations they normally access. Yet as first steps toward that network are concerned, it would be hard to find better places for Paris to begin than on the right bank and left bank of the Seine.

Bikes and buses: a natural fit?

In several cities on my European tour I found myself riding in “bikes and buses” lanes. On one level, this makes sense: cities wanting to smooth the passage of both public transit and active transportation might do so by setting aside a lane on a main artery for the shared use of bikes and buses. With relatively little traffic in that lane the buses can move more rapidly and thus attract more users, while also giving some official encouragement to cycling.

But is a bike-and-bus lane likely to attract new cyclists, beyond those who are already willing to brave city traffic? I don’t have the numbers, but I certainly have my doubts that people who are today unwilling to ride in car traffic will feel comfortable tomorrow in sharing a lane with even bigger buses.

In my head, I can rationalize that bus drivers are trained professionals and are much less likely to be careless, drunk, or driving while texting than the average car driver. Yet after nearly 40 years of frequent biking in busy cities, I still find it a scary adrenalin rush when a full-size city bus thunders by with inches to spare and then pulls over right to the curb in front of me.

Nowhere did the “bike and bus lane” paradigm seem more obviously flawed than in central London, where buses are nearly as numerous as taxis.

As luck would have it, my route each morning and evening in London neatly coincided with one of the much ballyhooed new “cycle superhighways”. These are painted a distinctive blue, protected for significant stretches by curbs between cyclists and cars, and they extend radially out from central London.

These routes are no doubt a significant improvement for city cyclists, and I was glad to be able to ride one into the central city each day. Yet the first time I started to relax and enjoy the ride, I was shocked to suddenly find myself turfed out into a bus-and-taxi lane.

An example of the “Cycle Superhighway” suddenly merging into a lane for buses and taxis (during rush hour) and for all motor traffic (during all other hours).

For the benefit of riders who have never seen a city bus before, a yellow sign proclaims that “This bus pulls in frequently”. If you can focus on this little yellow sign while you are being abruptly cut off by a vehicle 1000 times your weight and size, you can understand perfectly what is happening.

Though these interruptions to the bike lane were only a block or two in length, they also happened several times along the five kilometers I rode the CS2 (Cycle Superhighway) each morning and evening.

I can only imagine how frightening it would be to a first-time city cyclist who might venture out on this “protected cycle lane”, perhaps with a young child following, only to find themselves suddenly dodging buses.

In this respect the Cycle Superhighways fall short of basic standards that would be followed for any cycle route along any arterial road in any Dutch city.

This is likely one reason the Cycle Superhighways have failed, so far, to attract many riders beyond the young, fit and brave cyclists who would be riding anyway, regardless of specific bike infrastructure. On the stretch of “Superhighway” I rode frequently, weaving around buses and into the general traffic lanes is a necessary skill, unless you are content to make frequent stops and then wait patiently while many passengers embark and disembark from the bus ahead of you.

On two mornings I kept a mental count of how many cyclists passed me compared to the number of cyclists I overtook. When I maintained a pace of about 20 km/h, 8 or 10 cyclists overtook me for every one that I overtook. Nearly all of them appeared to be about half my age, though there were no children riding their own bikes, and I recall seeing only one young child being carried on a parent’s bike. This, of course, was an entirely different demographic than I had become used to while riding in Dutch cities.

The cycle riding population became more varied in the central core, with many people riding the reliable and widely available, but relatively heavy and slow, bike-share bikes. These trips tend to be short, and on many core city streets traffic is moving very slowly anyway, so biking probably feels safe enough to a much wider group of people. (Not safe in every way, mind you – there were a surprising number of cyclists wearing face masks as a defense against the polluted air.)

While the most congested streets in central London see significant use by cyclists of varying age on sturdy bike-share bikes (above), bike lanes on busier arterial roads into the core are still predominantly used by young, athletic cyclists on fast bikes (below).

The limited success so far of the Cycle Superhighways brings to mind an important principle for urban programs aiming to increase the number of cyclists:

Don’t build bike lanes for those who are cycling now. Build them for people who aren’t cycling now.

Changing a car-dominated city to a place where people of all ages feel secure in routinely biking to work, school or shopping is a difficult chicken-and-egg problem. You don’t get most urban dwellers to start riding bikes until there is wide network of safe biking spaces, connecting most people to most of their common destinations. But it’s hard to get politicians to spend political capital championing the transition to safe and clean transportation, when there are so few people biking.

It’s encouraging, then, that London’s cycling-promotion efforts go far beyond the high-profile but sparse network of cycle superhighways. As discussed in the excellent short film Cycling London’s Bicycle Super Highways, there is an accompanying push to create “Quietways” throughout London’s residential areas. This program, which simultaneously calms motor traffic while creating hassle-free routes for cyclists through residential areas, has the potential to connect many residents’ homes with major arteries. And it is only when people can safely get through and out of their own neighbourhoods on bike, that significant numbers of new riders will join those already using the protected lanes along major arteries.

As Chris Kenyon of employer association CyclingWorks says in the video,

Our road system actively excludes certain groups from taking part in active transport. … we see fewer women, fewer older residents, and almost no children whatsoever, able to cycle in our streets.  We think this is an issue of social justice. … Councils need to say, if active travel is important as a health strategy for the capital, then how do we make sure it’s available to everybody?”

Iain Simmons, Assistant Director of City Transportation, is also clear that the current preponderance of fast athletic riders is not the desired long-term goal:

Ultimately, here in the city, we’re looking for something where actually everybody slows down. A good speed for vehicles and cyclists to go is about 10 miles an hour, because the differential between them, and someone who is walking along at 3 miles an hour in the pedestrian lane, is actually more easy to understand and deal with. Try and bring that civility, and that calmness, into people’s journeys.”

Traffic calming, then, is paramount. It is worthwhile recalling that even in The Netherlands, with their vast network of protected bike lanes, most urban streets neither have nor need specific cycling infrastructure; planners just need to ensure that car traffic on side streets is low speed and low volume, and then biking can become a safe and convenient option for people ages 8 to 80.

Just do it

Finally, it is important to remember that not all of the transition to safe active transportation is led by municipal officials. Much of the leadership comes from ordinary citizens, who conclude that cycling is a sensible option in spite of an almost complete lack of dedicated cycle infrastructure. This is especially true where previous reliance on private cars has resulted in daily patterns of gridlock, and bikes are just as fast or faster than cars whether bikes are promoted or not.

On my first morning in Paris I was cheered to see a great variety of cyclists out on the streets creating unsanctioned patterns of mobility: turning traffic-snarled one-way streets into contra-flow cycling lanes, for example, or detouring around stalled traffic by taking whichever lane had some free space at the moment.

The next morning I came across several signs warning that due to construction, circulation through the Bastille area was “difficult”. When I approached the massive, multi-spoked traffic circle in front of the Bastille opera house, I was startled to see cyclists weaving through the creeping chaos of tourist buses, cars, delivery trucks and motorcycles. After watching this pageant for 15 minutes or so I realized it wasn’t so difficult after all, and I got back on my bike to join the parade for a few laps. In closing, then, here is my brief tribute to the Parisian avant-garde.

First principles for sustainable and equitable transportation

A review of Beyond Mobility

Also published at Resilience.org.

Beyond Mobility, Island Press, December 2017

Subway systems, trams, Bus-Rapid-Transit, high-speed trains, cars – these can all play useful roles in well-designed transportation systems. But we must not forget what still is and what should remain the world’s most important transportation method: walking.

That is one of the key messages of Beyond Mobility: Planning Cities for People and Places, a survey of urban planning successes and failures around the world.

Authors Robert Cervero, Erick Guerra and Stefan Al set out a general framework for transportation planning, in which the metric of “number of cars moved per hour” is replaced by an emphasis on place-making, with intergenerational sustainability, social equity, safety, and decarbonization as essential goals. The introduction to “urban recalibration” is followed by brief case studies from dozens of cities throughout the world.

First, do no harm to pedestrians

“For all the emphasis on cars and transit, walking remains the most globally important mode of transportation,” the authors write. “Globally, almost 40 percent of all trips are made by foot, and the figure is close to 90 percent in many smaller and poorer cities.”

In the Global South as in western Europe and North America, official transportation planning is dominated by the motoring classes, to the detriment of those who want to or have no choice but to walk. But Beyond Mobility cites many reasons why building safe cities for walkers is a global issue:

“Because walking produces almost no local or global pollution, creates no traffic fatalities, costs residents only the food needed to power their legs, has proven health benefits, and requires low infrastructure investments relative to highways or transit, maintaining high walking rates is critically important in the Global South.” (Beyond Mobility, page 173)

The public health consequences of a planning preference for automobiles are especially severe in the Global South, with deaths from air pollution and traffic accidents highest among the very people who cannot themselves afford cars. Therefore a shift in transportation policy is an obvious social equity issue.

In North America, after generations in which urban residents moved away from city cores to widely spaced suburbs, the trend is now reversing. The downtown areas of many major cities are once again highly sought after by residents and would-be residents, leading to huge price premiums for central-city residential properties.

A key reason for this preference is walkability. While time spent commuting by car tends to be stressful and unsatisfying1, a new generation has discovered the physical, emotional and social benefits of routine walking to work, school, shopping and entertainment.

This urban renaissance comes with obvious problems due to gentrification. A big part of the problem is scarcity: particularly in North America, desirably walkable neighbourhoods are now rare, while most urban residents must settle for neighbourhoods where basic services are distant and transportation options are expensive in terms of money, time, and/or personal safety.

Mobility when necessary, but not necessarily mobility

Real estate ads for suburban residences frequently highlight a key selling point – “close to the expressway”. By design, employment zones and residential districts are generally far apart in the post-war North American suburb. That has led to a situation where an important attribute for a residential neighbourhood is how easy it is to get far away from that neighbourhood each morning.

It’s a daunting task to reverse that trend, to change suburban settlement patterns to the point where many residents can work, shop, go to school, visit friends or go out to eat without getting into a car or boarding a train. Yet efforts at “sprawl repair” have begun in many places. Many of these efforts are guided by the concept of “place-making”, a central idea in Beyond Mobility. The authors quote urban designer Jan Gehl: “Place-making is turning a neighborhood, town or city from a place you can’t wait to get through to one you never want to leave.”2

Suburban shopping malls and suburban office parks come in for particular scrutiny. Both facilities are typically surrounded by hectares of parking lots. In theory it should be possible to redevelop these facilities (especially the many shopping centres which already stand vacant), creating more intensive mixes of residential, employment, commercial, educational and entertainment uses. The authors note that “One of the saving graces of huge surface parking lots is they can be easily torn up and rebuilt upon.” More generally, they state that

“Fortunately, suburban landscapes are malleable and for the most part can be easily adapted, modified, and reused. … In many ways, suburbs are the low-hanging fruit in the quest to create sustainable, highly livable, and more accessible places.” (Beyond Mobility, page 89–90)

This optimism notwithstanding, examples of successful suburban reconfigurations are rare in this book. In many cases, the authors note, redevelopment of a particular shopping mall or office complex produces an attractive mini-mix of services in a compact area, but is still too distant from most services to be “the kind of neighbourhood you never want to leave”.

One redevelopment option which is conspicuous by its absence in the pages of Beyond Mobility is what we might call the Detroit option. Instead of replacing empty suburban pavement with more intensive building patterns, perhaps there are some suburban districts which should become less intensive, returning to agricultural uses which would boost the sustainability of an urban area in other important ways.

Cycling receives very little attention in the book, even though two-wheeled, human-powered vehicles are already meeting the need for medium-distance transportation in many cities, with minimal infrastructure costs, many public health benefits, and almost no disruption of the primary transportation method, walking. The chapter on autonomous vehicles is also a bit of a puzzle. Though the authors are “cautiously optimistic” that driverless cars will enable a better “balance between mobility and place”, their discussion highlights several reasons to believe this technology may result in more Vehicle Miles Traveled and a greater disconnection from the social environment.

When it comes to transformational changes to the cores of major cities, however, the book is full of inspiring examples. In cities from San Francisco to Seoul, Bogotá to Barcelona, freeways have been replaced with boulevards, intersections have been reconfigured to make passage safer and more pleasant for pedestrians, single-use office complexes have incorporated retail and affordable housing, “park-and-ride” train stations have moved closer to an ideal of “walk-and-ride” as surrounding blocks are redeveloped.

Many of these urban recalibration efforts have their own flaws and limitations, but the value of Beyond Mobility is an even-handed recognition of both successes and failures. Above all, the authors emphasize, equitable, sustainable and convivial cities can’t be created all at once:

“urban recalibration calls for a series of calculated steps aimed at a strategic longer-range vision of a city’s future, advancing principles of people-oriented development and place-making every bit as much as private car mobility, if not more. … It entails a series of 1 to 2 percent recalibration ‘victories’ – intersection by intersection, neighborhood by neighborhood — that cumulatively move beyond the historically almost singular focus on mobility, making for better communities, better environments, and better economies.” (Beyond Mobility, page 211)
