I’ll admit I was a little skeptical when I cracked open Taras Grescoe’s latest book Straphanger, which is both paean to public transportation and an evisceration of car culture. Living happily car-free in New York, I feared I might be the choir to the Montrealer’s preaching. But while the book—part history, part travelogue, and part manifesto—might not seem terribly radical to city-dwellers, Grescoe makes the argument for mass transit in a way you might not have heard before.

In the course of writing Straphanger, Grescoe visited a dozen cities across the world and spent considerable time getting to know their transit systems, figuring out how and why they work (or don’t). After a short prologue in Shanghai, Grescoe starts his global commute in New York, where the subway system maintains a tetchy coexistence with street-level planning that’s historically favored cars over pedestrians. Subsequent cities each provide a slightly different perspective on transportation: Phoenix gives us a primer on the difficulties of low-density sprawl; Copenhagen is a model of bike-friendly infrastructure; Bogotá’s rapid bus system proves how quickly a mass transit network can be rolled out from scratch.

Despite being one of the most crowded transit systems in the world, Moscow’s Metro is endowed with spacious, luxuriously appointed stations. Image via Wikimedia Commons.

At the newly unveiled Web site Shape Vancouver 2050, users are given a digital model of the Vancouver skyline, the ability to extrude buildings upwards, and a visual gauge of the resulting effects on the city’s downtown. As the user drags the digital towers higher and population density increases, meters at the bottom of the screen go up too—energy saved, carbon use curbed, dollars added to the city coffers.

It’s a neat tool, if a bit of a one-liner: the more tall buildings you insert, the better things get; make nearly all the buildings tall and you’ve created an “Urban Paradise!” (Leave most of the buildings as low-rises and you’re chided for fostering sprawl.) It’s not entirely clear whether the site’s creators—the architecture firm Perkins +Will and the developer Concord Pacific—intended Shape Vancouver as an honest solicitation of planning input from the public, or a sneaky way to educate (or indoctrinate?) residents in the environmental benefits of high density. Either way, their message is clear: Want a better Vancouver? Build tall.

Christoph Gielen has a unique perspective—literally—on the sprawl that has taken over so much of the American built landscape since the 1960s. As someone who has spent a lot of time in helicopters, looking down on the eerily perfect geometries of the nation’s suburbs, the German artist knows just how artificial, and unsustainable, these communities really are. With his Arcadia series, a portion of which we’re featuring here, Gielen hopes to spur viewers to think about the consequences of what they’re seeing (and, perhaps, where they live). “With these pictures, I am interested in exploring the intersection of art and environmental politics,” Gielen says. “I hope to trigger a reevaluation of our built environment and the methods of its development, to ask: What can be considered a viable, ecologically sound growth process?” Click here to launch a slide show of Gielen’s photographs.
