Transportation—the movement of people and goods—is the lifeblood of a city. Inadequate transport systems constrain a city’s economy and vitality. But making a city too dependent on motorized transport can cause a host of other problems: traffic jams and deadly accidents, debilitating air pollution, and the loss of valuable land to streets, highways, and parking lots.
Car- and truck-centered transportation systems run the risk of becoming like clogged arteries: they are bad not only for the vitality and attractiveness of cities, but also for urban residents’ health, local environmental quality, and the global climate. As experience worldwide shows, wide-ranging options are available to cities wanting to reduce the footprint of their transportation systems. The opportunities are matched by the urgency with which cities everywhere need to act.
“To become sustainable, cities need to sharply reduce reliance on automobiles and to work to ensure a better mix of well-integrated transportation modes.”
