My proposal to dramatically reduce traffic accidents. Eliminate all stop lights. Instead, institute roundabouts and stop signs. In emergency situations, traffic police.

The logic? Most accidents, often fatal, are people racing through intersections, not paying attention to those around them. The root cause here inattention. From a design perspective, what requires attention? Yes, roundabouts and stop signs.

In the most complex and largest intersections where horrific accidents regularly happen, no accidents occur when power outages take out traffic lights. People have to pay attention.

You have a better idea? Pitch it.
