… for whatever it’s worth…

This month we highlight studies cited on a Washington State Department of Transportation page showing that accidents on roundabouts are less frequent and not as serious as at traditional four-way intersections.

According to the website, roundabouts reduced injury crashes by 75 percent at intersections where stop signs or signals were used previously for traffic control, according to a study by the Insurance Institute for Highway Safety (IIHS). Studies by the IIHS and Federal Highway Administration have shown that roundabouts typically achieve a:
• 37 percent reduction in overall collisions;
• 75 percent reduction in injury collisions;
• 90 percent reduction in fatality collisions; and a
• 40 percent reduction in pedestrian collisions.

An attendant YouTube video provides substantiation for these numbers.
