Skippa trafiksignalerna?

Salon-artikeln Why don't we do it in the road? (registrering eller "day pass" krävs) handlar om att skippa trafiksignalerna. Några citat ur artikeln:

A new school of traffic design says we should get rid of stop signs and red lights and let cars, bikes and people mingle together. It sounds insane, but it works.
...
"One of the characteristics of a shared environment is that it appears chaotic, it appears very complex, and it demands a strong level of having your wits about you," says U.K. traffic and urban design consultant Ben Hamilton-Baillie, speaking from his home in Bristol. "The history of traffic engineering is the effort to rationalize what appeared to be chaos," he says. "Today, we have a better understanding that chaos can be productive."
...
Reversing decades of conventional wisdom on traffic engineering, Hamilton-Baillie argues that the key to improving both safety and vehicular capacity is to remove traffic lights and other controls, such as stop signs and the white and yellow lines dividing streets into lanes. Without any clear right-of-way, he says, motorists are forced to slow down to safer speeds, make eye contact with pedestrians, cyclists and other drivers, and decide among themselves when it is safe to proceed.
...
[T]he ability of traffic to move smoothly through the built environment, depends on performance of your intersections, not on your speed of flow between intersections." And intersections, he says, work much more efficiently at lower speeds. "At 30 miles per hour, you frequently need control systems like traffic signals, which themselves mean that the intersection is not in use for significant periods of time. Whereas at slower speeds vehicles can move much more closely together and drivers can use eye contact to engage and make decisions. So you get much higher capacity."
