A Study of the Traffic Safety at Reduced Conflict Intersections in Minnesota

Wednesday, July 26, 2017 - 17:30

In 2010, the Minnesota Department of Transportation installed the first Reduced Conflict Intersection (RCI) in the City of Willmar. Since 2010, seven more were constructed, with more planned. The RCI concept is gaining popularity in several states, including Maryland, Mississippi, Missouri, North Carolina, and Wisconsin. This report includes findings from a safety performance evaluation of Minnesota Reduced Conflict Intersections. This evaluation found: A 100% reduction of fatal and serious injury right-angle crashes; A 77% reduction of all severity right-angle crashes; A 50% reduction of injury crashes. Additionally, compared to their untreated counterparts, Reduced Conflict Intersections showed significantly fewer severe right-angle crashes and severe crashes, and the crashes observed at an RCI intersection were of lower crash severity than their untreated counterparts.
