Maybe it would be a good idea to remove some traffic signals and signs on the roads. After all maybe people would act like adults and be careful and share the roads.
There's only one way to find out. Turn off the lights and see what happens. Martin Cassini started the FiT Roads site which advocates for the removal of traffic lights.
The only way to find out what happens when you remove traffic lights is to... well... remove traffic lights. Two videos by FiT show what can happen. Part 1: Roads unfit for people and Part 2: Roads FiT for People show how dramatic the change can be. Contrary to many people's expectations drivers are willing to share the road and act responsibly. Not to say that the results are perfect. FiT's own video points out at least one potential shortcoming of the project. Still... it's an experiment worth taking seriously.
Counterintuitive thinking at it's best. Now with real world proof.
