Abstract

Minnesota has supported rural intersection research regarding crashes and their causality for the past several years. The Minnesota Department of Transportation initiated research through the University of Minnesota and CH2MHill to identify the most prevalent type and most likely causes of crashes at rural intersections. Right angle crashes at rural thru-stop intersections were identified as most common, and the greatest cause of these right angle crashes was failure of drivers to recognize unsafe gaps in the traffic stream they were hoping to enter or cross. As additional data has been collected in Minnesota and eight other states, the methodology for identifying problem intersections, collecting macroscopic driver gap rejection behavior, and conclusions about gap acceptance and rejection have been validated and support the need for Cooperative Intersection Collision Avoidance Systems.
