Rural two-lane roads generally have only a 12 inch area separating opposing traffic. This area is represented by the double yellow line. Because opposing traffic is not separated by more than the double yellow line, a major crash problem on these roads involves (1) vehicles crossing the centerline and striking an opposing vehicle head on, (2) vehicles crossing the centerline and sideswiping an opposing vehicle, or (3) vehicles crossing the centerline and running off the road to the left. On Minnesota Trunk Highways (TH) for the period 2000-2002, head-on, sideswipe opposing, and run off the road left crashes account for 25% of all crashes on rural 2-lane roads, while accounting for only 11% of all TH crashes statewide. Additionally, head-on, sideswipe opposing, and run off the road left crashes have the three highest average cost per crash, valued at $289,000, $111,000 and $69,000, respectively. These crashes are significantly overrepresented AND they are the most severe types of crashes. Given the extremely severe nature of the target crashes, and their overrepresentation on rural 2-lane roads, targeting these crashes for reduction by using CLRS presents an excellent opportunity to help move Minnesota Towards Zero Deaths (TZD). This report examines the relationship between CLRS and traffic safety.
