Cities for People
The world's cities are in trouble. In Mexico City, Tehran, Bangkok, Shanghai, and hundreds of other cities, the quality of daily life is deteriorating. Breathing the air in some cities is equivalent to smoking two packs of cigarettes per day. In the U.S., the number of hours commuters spend sitting in traffic going nowhere climbs higher each year.
In response to these conditions, we are seeing the emergence of a new urbanism. One of the most remarkable modern urban transformations has occurred in Bogotá, Colombia, where Enrique Peñalosa served as Mayor for three years, beginning in 1998. When he took office he did not ask how life could be improved for the 30% who owned cars; he wanted to know what could be done for the 70% -- the majority -- who did not own cars.
Peñalosa realized that a city that is a pleasant environment for children and the elderly would work for everyone. In just a few years, he transformed the quality of urban life with his vision of a city designed for people. Under his leadership, the city banned the parking of cars on sidewalks, created or renovated 1,200 parks, introduced a highly successful bus- based rapid transit system, built hundreds of kilometers of bicycle paths and pedestrian streets, reduced rush hour traffic by 40%, planted 100,000 trees, and involved local citizens directly in the improvement of their neighborhoods. In doing this, he created a sense of civic pride among the city's eight million residents, making the streets of Bogotá in strife-torn Colombia safer than those in Washington, D.C.
Enrique Peñalosa observes that "high quality public pedestrian space in general and parks in particular are evidence of a true democracy at work." He further observes: "Parks and public space are also important to a democratic society because they are the only places where people meet as equals. In a city, parks are as essential to the physical and emotional health of a city as the water supply." He notes this is not obvious from most city budgets, where parks are deemed a luxury. By contrast, "roads, the public space for cars, receive infinitely more resources and less budget cuts than parks, the public space for children. Why," he asks, "are the public spaces for cars deemed more important than the public spaces for children?"
Now government planners everywhere are experimenting, seeking ways to design cities for people not cars. Cars promise mobility, and they provide it in a largely rural setting. But in an urbanizing world there is an inherent conflict between the automobile and the city. After a point, as their numbers multiply, automobiles provide not mobility but immobility. Congestion also takes a direct economic toll in rising costs in time and gasoline. And urban air pollution, often from automobiles, claims millions of lives
