Gauging the safety effects of rumble strips at rural intersections

A common cause of traffic accidents at low-volume, rural intersections is failure by drivers on the minor approaches to slow and stop for stop signs. One device that is frequently used by state DOTs to mitigate this problem is the rumble strip. When installed on rural intersection approaches, rumble strips are believed to supplement other traffic control devices in calling attention to the junction ahead and the traffic control used there. While rumble strips are generally perceived to be effective in reducing intersection crashes, there is no consensus on their effectiveness. This report for the Wisconsin DOT Bureau of Highway Operations gathers a sampling of research studies and other documentation that objectively examine the safety effects of rumble strips installed on the approaches to rural intersections.
