The Null Device
Momus makes a few points about car-centric urban design:
It's always seemed to me that a society's respect for humanity might be better measured by the length of its pedestrian crossing signals than by any number of abstract declarations of support for "universal human rights". Cars are the closest thing we have in our society to predators, capable of picking off the weak; they're malevolent steel sharks or pumas, cruising our cities, hogging the head of the food chain.
Car signals stay green up to ten times longer than foot traffic signals do. Pedestrians sometimes only get a cross signal when they "apply" for it by pressing a request button. It just seems that car traffic is seen as "economically rational" and "necessary", whereas foot traffic is somewhat dilettante, an afterthought, unimportant.
Often, in studies, only the motorist's convenience is taken into account. Manhattan traffic police admitted, for instance, that a barrier scheme to prevent pedestrians crossing 6th Avenue by forcing them to walk up the block to the next crossing point was deemed a success because it reduced traffic wait times. The extra time added to the pedestrian's journey wasn't even measured, though, and this despite the fact that 6 or 7 times more people were crossing town on foot at these locations than in cars.
