In the US, traffic engineers are beginning to rethink the dictum that the car is king and pedestrians are well advised to get the hell off the road. In West Palm Beach, Florida, planners have redesigned several major streets, removing traffic signals and turn lanes, narrowing the roadbed, and bringing people and cars into much closer contact. The result: slower traffic, fewer accidents, shorter trip times. "I think the future of transportation in our cities is slowing down the roads," says Ian Lockwood, the transportation manager for West Palm Beach during the project and now a transportation and design consultant. "When you try to speed things up, the system tends to fail, and then you're stuck with a design that moves traffic inefficiently and is hostile to pedestrians and human exchange."
The common thread in the new approach to traffic engineering is a recognition that the way you build a road affects far more than the movement of vehicles. It determines how drivers behave on it, whether pedestrians feel safe to walk alongside it, what kinds of businesses and housing spring up along it. "A wide road with a lot of signs is telling a story," Monderman says. "It's saying, go ahead, don't worry, go as fast as you want, there's no need to pay attention to your surroundings. And that's a very dangerous message."
How to Build a Better Intersection
2. Install art: The height of the fountain indicates how congested the intersection is.
3. Share the spotlight: Lights illuminate not only the roadbed, but also the pedestrian areas.
4. Do it in the road: Cafés extend to the edge of the street, further emphasizing the idea of shared space.
5. See eye to eye: Right-of-way is negotiated by human interaction, rather than commonly ignored signs.
6. Eliminate curbs: Instead of a raised curb, sidewalks are denoted by texture and color.
