Fewer Traffic Signs, Better Safety?

Via Liz (via Simon):

"Imagine what would happen if you took down road signs and traffic signals. More accidents would surely result, or at least significant confusion and slower traffic. Or would it? The surprising thing is that a number of cities around the world have actually done this, and experienced dramatic declines in traffic accidents.

The idea is based on an urban design philosophy known as “shared space.” When drivers, pedestrians and bicyclists are forced to develop their own natural ways of interacting with each other, goes the thinking, they work out better social behaviors than the rule-driven behaviors dictated by professional traffic engineers. This does not mean an abandonment of design considerations, but rather a commitment to the larger public space designs instead of overly prescriptive traffic control devices such as traffic lights, signs and road markings.

The Dutch town of Drachten adopted this “unsafe is safe” approach in 2007 and found that casualties at one junction dropped from thirty-six over the previous four years to only two in the two years following the removal of traffic lights. Traffic jams no longer occur in the town’s main junction, which handles 22,000 cars a day."
