New resource on multilane roundabouts: reducing violations and crashes

Cover of LRRB roudnabout brochureWhile multilane roundabouts almost always reduce fatal and severe crashes, failure to yield and improper lane-use violations can lead to a higher number of minor crashes. To better understand and address these violations at multilane roundabouts, U of M researcher John Hourdos has conducted two studies funded by the Minnesota Local Road Research Board (LRRB).

A new LRRB brochure summarizes findings from these studies and offers highlights of local agency experience to date. The brochure, illustrated with photographs and diagrams, includes sections on what can be expected with multilane roundabouts, suggested design modifications, the need to educate drivers, and resources/research in progress.
