First principles for sustainable and equitable transportation

A review of Beyond Mobility

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)

The mobility maze

Also published at Resilience.org.

Mobility is good, so more mobility is better, right? If only it were so simple.

Mobility, after all, is generally less important to people than accessibility. When we go somewhere it’s not the movement that’s valuable, it’s the access to something – a school, shopping, a workplace, a friend’s house or a park – that really counts. That holds true whether we’re walking across the street, taking a subway to work, or navigating suburban traffic in an SUV enroute to the big-box store.

A prioritization of mobility in transportation planning, unfortunately, often has the result of reducing accessibility.1 Particularly in North America, a century-long focus on mobility has resulted in drastic changes to urban and suburban landscapes. As we travel into a new century facing the challenges of climate change and reduced energy affordability, the inherited legacy of mobility-fixation presents major challenges to average citizens and land-use planners alike.

If we look back just over a century, both the bicycle and then the car initially increased both mobility and accessibility for many people. True, it was a thrill to travel at speeds that had previously seemed inhuman. But fast wheeled transportation also opened up many new opportunities for late nineteenth and early twentieth century people. The local school, local stores, local employers were no longer the only options – suddenly many people could easily access opportunities on the other side of the city or the other side of the county.

The increase in accessibility was especially significant to rural Americans whose social worlds had been tightly circumscribed by the distance they could walk or ride a slow horse. There was very good reason that “Of the first million Model Ts that Ford sold, 64% went to the farm and small town market.”2

Yet as quickly as cars increased accessibility for rural people, cars decreased accessibility for a great many city-dwellers, especially those not privileged enough to drive a car. The first change was that on many streets, it was no longer safe to access the other side of the road by foot, as people had done for millennia. If the threat of being run down was not enough, PR campaigns and then laws created the new crime of jaywalking. In busy areas, pedestrians had to walk down the block to a traffic light, wait for their turn to cross, and then double back to the destination. Thus in millions of situations in cities every hour, cars increased accessibility for their drivers while reducing accessibility for people on foot.

A single-minded focus on mobility, however, would introduce far more sweeping changes over time. Once large numbers of people moved through cities by car, big parking lots were needed between stores. Whether on foot or behind the wheel, people now needed to move farther to get where they wanted to go. New zoning regulations separated workplaces from shopping, education and residential districts, requiring people to travel farther.

This mobility focus reached its fullest expression with the mid-twentieth century expressway, AKA “controlled access highway”. All across North America, vast swaths of land were devoted to traffic lanes reserved for high-speed vehicles, with entrances and exits only at widely spaced intervals. Particularly when these expressways slashed through existing cities, they instantly disrupted accessibility in previously thriving neighbourhoods, making a host of urban amenities more difficult to reach for those traveling on foot or by bicycle.

As a general rule we might say that more mobility results in more accessibility, if all other relevant factors remain the same. But when we increase mobility, many other factors do tend to change, either immediately or over the long term, and often the end result is less accessibility.

Can you get there from here?

When looking at maps of North American suburbs and exurbs, an old joke comes to mind. An elderly villager, when asked for directions from his hamlet to a town across the county, answers, “Well, if I wanted to get to [Coventry] [Mariposa] [insert favourite town name], I sure as heck wouldn’t be starting from here”.

But for better or worse, we have to start from right where we are. So in considering the challenges in correcting a decades-long focus on mobility at the expense of accessibility, I’ll conclude this post with a few examples taken from my region.

In the grandly named “Greater Toronto Area”, a heavy reliance on expressways has made the later introduction of commuter rail services both more difficult and less effective. The extraordinary allocation both of land and public finances to expressways encouraged people to commute by car, from far outside the city to jobs in Toronto or its suburbs. But when, inevitably, rush hours lengthened and gridlock became common, belated extensions of mass transit services had to fit into the spaces between expressways, parking lots and major arterial roads. As a result, these transit facilities are neither particularly accessible nor attractive to people who don’t drive.

The Google satellite map below, for example, shows a shopping mall called Scarborough Town Centre, which is attached to a station for a light rail line to downtown.

This “City Centre” concentrates a wide variety of functions including retail stores, restaurants, theatres, office buildings and government services. But because so many people in this area will arrive by car, these functions must be widely spaced to allow many hectares of access roads and parking. Thus the City Centre is not accessible by foot except for determined hikers. Furthermore, the 14-lane expressway Highway 401 is adjacent to the complex, creating a wide separation between this centre and any residential or commercial districts to the immediate north.

As illustrated here, a residence just north of the expressway is only about 800 meters from the train station. But getting past the auto-induced obstacles involves a bike ride of almost 3 km. And it’s not a pretty ride. As shown in the Google Streetview image below, crossing the bridge over the 401 means a noisy, windy, polluted journey over more than a dozen lanes of car and truck traffic.


The need to accommodate car traffic is an even greater handicap for commuter rail stations further outside the city. To the east of Toronto, the GO Transit commuter rail line currently ends on the outskirts of Oshawa, about an hour’s train ride from downtown Toronto. Although several buses bring commuters here from surrounding suburban areas, huge numbers of people arrive by car, and the seemingly endless parking lots are never adequate. The presence of these parking lots, on the other hand, is a barrier to creation of any major, concentrated residential or commercial district within walking distance of this station.

Even for commuters from nearby residential areas in the upper left and right of this image, getting to the station without a car would include navigating the spaghetti-string intersection of Highway 401. (Also shown in image at the top of this post.) Cyclists and pedestrians are seldom seen crossing that bridge in droves.

Recently-built residential neighbourhoods in this area show the same strong emphasis on mobility over accessibility. Here are two examples from the sprawling subdivisions that stretch far to the north of Highway 401.

A small strip mall provides a few services, including a restaurant. As shown here, if you could walk directly to the restaurant from an address just one short block away, you’d only have to travel 120 metres – but as indicated by Google Maps, the actual walking distance is 1 kilometre.

Within these neighbourhoods the intentional lack of a simple grid street plan, replaced instead by irregular blocks, loops and cul-de-sacs, supposedly makes areas like these unattractive to through traffic and therefore quieter. An unavoidable side effect, however, is a major reduction in the number of neighbours or services accessible within a couple of hundred metres. In example below, two neighbours who would be only 135 metres apart in a grid system are instead faced with a 1.2 km one-way trip. In other words, mobility-focused design gives such neighbourhoods poor accessibility for anyone but drivers.

No easy fix

Achieving a transportation mix suited to the coming century will require a focus on accessibility more than mobility. This is a tall order in areas where an expensive, land-use-dominating infrastructure is currently devoted to car culture. It would be comforting to think that this built infrastructure took several decades to construct, and we can now spend several decades fixing the inherited problems. However, the urgency of reducing carbon emissions means we do not have several decades to respond to our current challenges.

Fortunately, there have been citizens’ movements, city governments, urban planners and scholars in many countries who have already provided many valuable lessons. A new book, Beyond Mobility,3 summarizes many inspiring illustrations, and I’ll turn to that book in the next installment in this series.

A measured response to surveillance capitalism

Also published at Resilience.org.

A flood of recent analysis discusses the abuse of personal information by internet giants such as Facebook and Google. Some of these articles zero in on the basic business models of Facebook, and occasionally Google, as inherently deceptive and unethical.

But I have yet to see a proposal for any type of regulation that seems proportional to the social problem created by these new enterprises.

So here’s my modest proposal for a legislative response to surveillance capitalism1:

No company which operates an internet social network, or an internet search engine, shall be allowed to sell advertising, nor allowed to sell data collected about the service’s users.

We should also consider an additional regulation:

No company which operates an internet social network, or an internet search engine, shall be allowed to provide this service free of charge to its users.

It may not be easy to craft an appropriate legal definition of “social network” or “search engine”, and I’m not suggesting that this proposal would address all of the surveillance issues inherent in our digitally networked societies. But regulation of companies like Facebook and Google will remain ineffectual unless their current business models are prohibited.
 

Core competency

The myth of “free services” is widespread in our society, of course, and most people have been willing to play along with the fantasy. Yet we can now see that when it comes to search engines and social networks, this game of pretend has dangerous consequences.

In a piece from September, 2017 entitled “Why there’s nothing to like about Facebook’s ethically-challenged, troublesome business model,” Financial Post columnist Diane Francis clearly described the trick at the root of Facebook’s success:

“Facebook’s underlying business model itself is troublesome: offer free services, collect user’s private information, then monetize that information by selling it to advertisers or other entities.”

Writing in The Guardian a few days ago, John Naughton concisely summarized the corporate histories of both Facebook and Google:

“In the beginning, Facebook didn’t really have a business model. But because providing free services costs money, it urgently needed one. This necessity became the mother of invention: although in the beginning Zuckerberg (like the two Google co-founders, incidentally) despised advertising, in the end – like them – he faced up to sordid reality and Facebook became an advertising company.”

So while Facebook has grandly phrased its mission as “to make the world more open and connected”, and Google long proclaimed its mission “to organize the world’s information”, those goals had to take a back seat to the real business: helping other companies sell us more stuff.

In Facebook’s case, it has been obvious for years that providing a valuable social networking service was a secondary focus. Over and over, Facebook introduced major changes in how the service worked, to widespread complaints from users. But as long as these changes didn’t drive too many users away, and as long as the changes made Facebook a more effective partner to advertisers, the company earned more profit and its stock price soared.

Likewise, Google found a “sweet spot” with the number of ads that could appear above and beside search results without overly annoying users – while also packaging the search data for use by advertisers across the web.
 

A bad combination

The sale of advertising, of course, has subsidized news and entertainment media for more than a century. In recent decades, even before online publishing became dominant, some media switched to wholly-advertising-supported “free” distribution. While that fiction had many negative consequences, I believe, the danger to society was taken to another level with search engines and social networks.

A “free” print magazine or newspaper, after all, collects no data while being read.2 No computer records if and when you turn the page, how long you linger over an article, or even whether you clip an ad and stick it to your refrigerator.

Today’s “free” online services are different. Search engines collate every search by every user, so they know what people are curious about – the closest version of mass mind-reading we have yet seen. Social media not only register every click and every “Like”, but all our digital interactions with all of our “friends”.

This surveillance-for-profit is wonderfully useful for the purpose of selling us more stuff – or, more recently, for manipulating our opinions and our votes. But we should not be surprised when they abuse our confidence, since their business model drives them to betray our trust as efficiently as possible.
 

Effective regulation

In the flood of commentary about Facebook following the Cambridge Analytica revelations, two themes predominate. First, there is a frequently-stated wish that Facebook “respect our privacy”. Second, there are somewhat more specific calls for regulation of Facebook’s privacy settings, terms of sale of data, or policing of “bot” accounts.

Both themes strike me as naïve. Facebook may allow users a measure of privacy in that they can be permitted to hide some posts from some other users. But it is the very essence of Facebook’s business model that no user can have any privacy from Facebook itself, and Facebook can and will use everything it learns about us to help manipulate our desires in the interests of paying customers. Likewise, it is naïve to imagine that what we post on Facebook remains “our data”, since we have given it to Facebook in exchange for a service for which we pay no monetary fee.

But regulating the terms under which Facebook acquires our consent to monetize our information? This strikes me as an endlessly complicated game of whack-a-mole. The features of computerized social networks have changed and will continue to change as fast as a coder can come up with a clever new bit of software. Regulating these internal methods and operations would be a bureaucratic boondoggle.

Much simpler and more effective, I think, would be to abolish the fiction of “free” services that forms the façade of Facebook and Google. When these companies as well as new competitors3 charge an honest fee to users of social networks and search engines, because they can no longer earn money by selling ads or our data, much of the impetus to surveillance capitalism will be gone.

It costs real money to provide a platform for billions of people to share our cat videos, pictures of grandchildren, and photos of avocado toast. It also costs real money to build a data-mining machine – to sift and sort that data to reveal useful patterns for advertisers who want to manipulate our desires and opinions.

If social networks and search engines make their money honestly through user fees, they will obviously collect data that helps them improve their service and retain or gain users. But they will have no incentive to throw financial resources at data mining for other purposes.

Under such a regulation, would we still have good social network and search engine services? I have little doubt that we would.

People willingly pay for services they truly value – look back at how quickly people adopted the costly use of cell phones. But when someone pretends to offer us a valued service “free”, we endure a host of consequences as we eagerly participate in the con.

1 The term “surveillance capitalism” was introduced by John Bellamy Foster and Robert W. McChesney in a perceptive article in Monthly Review, July 2014.

3 There would be a downside to stipulating that social networks or search engines do not provide their services to users free of charge, in that it would be difficult for a new service to break into the market. One option might be a size-based exemption, allowing, for example, a company to offer such services free until it reaches 10 million users.

3 cheers for A2Bism: a review of ‘Copenhagenize’

How do we get beyond the dependency-inducing trap of car culture? After 100 years in which auto-oriented infrastructure has dominated public works spending and reshaped civic life, how can we make our streets safe and healthy spaces?

Copenhagenize:
The Definitive Guide to Global Bicycle Urbanism
(200 colour illustrations, 296 pages), March 2018, Island Press

These questions were suggested in discussion with a reader following my last post, Speeding Down a Dead End Road. There are many ways to approach this subject – and one of the best is to read Copenhagenize: The Definitive Guide to Global Bicycle Urbanism, a just-released book by Mikael Colville-Andersen which fortuitously landed in my inbox last week.

Colville-Andersen is a Canadian-Danish designer who started photographing people on bicycles in Copenhagen in 2006. This pastime quickly became the popular Cycle Chic blog, and then grew into Copenhagenize Design Co., which has now helped scores of cities improve their urban transportation mix. Copenhagenize, the book, is a great summary not only of the lessons learned by Copenhagen over the past forty years, but also the lessons learned by Colville-Andersen and his associates in many cities over the past 10 years.

First a brief word about what is both the book’s major limitation and its great strength: this is a guide to “bicycle urbanism” – it doesn’t pretend to cover cycling in rural or small-town areas.

In a move away from car culture, urban cycling is definitely the low-hanging fruit. Short trips under about 7 km make up a large proportion of trips within cities. Furthermore, the many costs of car culture – especially air pollution, and crashes that kill and maim – are readily evident in cities, while much-touted benefits such as speed and convenience are typically negated by gridlock. So it should be easy to persuade many average citizens to get out of cars and take to the streets on bicycle – if those streets can be made convenient and safe for human-powered transportation.

Let’s start with “convenient”.
 

A simple motivation

Extensive surveys have found that most Copenhagen cyclists are not motivated primarily by health concerns, or a concern for the environment, or a desire to save money – they ride bike because it’s the most convenient way to get around their city. This leads Colville-Andersen to stress a basic principle:

“I know exactly what you want. It’s the same thing that I want. Indeed, it’s what every homo sapien who has ever lived wants: a direct line from A to B when we’re transporting ourselves. … This is the most basic principle in transport planning. I call it A2Bism.” (Copenhagenize, pg 146)

Taking the most direct line is especially important when we’re getting around under our own steam. Yet for seventy-five years traffic planners concentrated on giving the best routes to cars, while introducing detours for foot-powered residents. Colville-Andersen sums up both this history of mistakes, and the simple solution, in these simple “traffic planning guide” graphics.

The two graphics on the left summarize the rupture of an ancient pattern of city life  by car culture – including, he emphasizes, in cities such as Copenhagen and Amsterdam.

On the right is the guide used by bicycle-friendly cities in recent decades. While cities in Denmark and the Netherlands have seen tremendous growth in cycling since they adopted this approach in the 1970s, a significant uptick in active transportation has also begun in many other cities, including a few in North America.

All too often in North America, however, new bike routes are added in out-of-the-way locations where they, predictably, serve few riders going about daily tasks like getting to and from work.1 If we were serious about encouraging rather than discouraging cyclists, we would allocate safe space for them on the most direct routes.

The Copenhagenize approach is illustrated at the right side of the graphic above: safe and healthy modes of active transportation are given direct routing, while polluting and dangerous cars and trucks get the frequent jogs and detours.
 

Safe space

Cycle-friendly planning isn’t quite as simple as drawing lines on a map or on the streets. While Colville-Andersen emphasizes that good urban cycling infrastructure is far cheaper than what we routinely spend on car infrastructure, we do need to budget for something besides a little paint:

“Hastily painted pictograms in the middle of car lanes are not infrastructure. They are the awkward watermark of lazy politicians and lazier transport professionals.” (Copenhagenize, pg 77)

Where streets must be shared by pedestrians, cyclists, and cars, trucks and buses, and motorized traffic will move more than 40 km/h, mere painted bike lanes will not provide an adequate measure of safety – some sort of physical separation is required. Having a row of parked cars between the cycle lane and the moving traffic is one good strategy. (In North America, however, the order is often reversed, with cycle lanes between the parked cars and moving traffic, precisely in the “door zone” where a driver opening the door of a parked car might knock a cyclist directly into the passing traffic.)

If Copenhagen now illustrates everything in Colville-Andersen’s chapter “Best Practice Design and Infrastructure”, it’s not because the Danes have always got it right. In fact, he says, all the cycle-planning mistakes frequently being made in other jurisdictions have also been made in Copenhagen. Other cities can save a lot of time and money if they don’t try to “reinvent the wheel”.

Waiting at a signalized intersection on a bike lane in Almetyevsk, Republic of Tatarstan

Colville-Andersen gives advice on many specifics: what is the minimum width for separated bike lanes, and when is it time to widen them further; what kind of intersection spacing works to keep cyclists safe from right-turning cars; under what circumstances is a bi-directional cycle lane a good option; how can cycle lanes be safely routed past bus stops. Yet the basic typology for bike lanes is based on just two data points: how many cars does a road carry, and what is the speed. Based on these two issues, he says, there are a grand total of four basic designs:

“Four. There are only four basic designs in Danish bicycle planning. One of these four fits every street in the Danish Kingdom and, indeed, every street in every city in the world.” (Copenhagenize, page 176)

In North America, in spite of a resurgence in urban cycling over the past ten years, no major city yet enjoys a bicycle “mode-share” of 10%. In Copenhagen and in Dutch cities such as Groningen, meanwhile that mode-share is now more than 40% – with the remainder split between buses, trains, cars, and walking.

Colville-Andersen emphasises, however, that “Copenhagen wasn’t always Copenhagen …. This city was as car-clogged as anywhere else on the planet through the 1950s and 1960s.” (Copenhagenize, page 64)

The growth of cycling culture there required massive public demonstrations in the 1970s, decades of work, and leadership by municipal officials with real vision. A key barrier is to get beyond the idea that we shouldn’t invest in cycling, because only a few people are willing to ride bike in our current urban environments:

“That misconception that a city has to build infrastructure for the people cycling now, as opposed to the 20-25 percent of the population that could be cycling, still reigns supreme.” (Copenhagenize, page 199)

 
 

Perfect synergy

Copenhagenize is a superb manual on all the important details of bike infrastructure design and operation. It’s a great ‘how-to’ guide for making cities safe and convenient for active transportation. Indeed, it’s a great book on the factors that, in the millennia before the destructive onset of car culture, made cities very attractive places to live:

“We have been living together in cities for more than 7,000 years. By and large, we used those seven millennia to hammer out some serious best-practices about cohabitation in the urban theater and the importance of social fabric. We threw most of that knowledge under the wheels of the automobile shortly after we invented it ….” (Copenhagenize, page 13)

In the struggle to redemocratize our streets, he says, the bicycle will play a key role: “This most human form of transport represents the perfect synergy between technology and the human desire to move. It is the most perfect vehicle for urban living ever invented.”

1A recent example in my area is the stalled plan to shrink car lanes and add bicycle lanes on a section of Toronto’s main through street, Yonge Street. The mayor and many councillors want instead to send local cyclists on a detour to the west, while preserving the direct route for motorists.
