By converting appropriate traffic light intersections into roundabouts, we'd save countless hours and huge amounts of fuel. We'd also save lives. If you want a no brainer for how to speed things along in Los Angeles traffic, with no downside, this is it! The Insurance Institute for Highway Safety, an independent research group, estimates that converting intersections with traffic lights to roundabouts reduces all crashes by 37% and crashes that involve an injury by 75%. One national study of ten intersections that could have been turned into roundabouts found that vehicle delays would have been reduced by 62-74% (nationally saving 325,000 hours of motorists’ time annually) and 235,000 gallons of fuel.
