Safety Performance of Shoulder Rumble Stripes on Rural Roadways

Roadway departure crashes are most common on rural, two lane roads. The Missouri Department of Transportation used a combination of shoulder rumble strips, shoulder widening, and pavement resurfacing as countermeasures on more than 400 centerline miles of rural roads. Crash modification factors (CMFs) were calculated for the treatment as a before and after study using the Empirical Bayes method. CMFs for 20 different crash categories were calculated. Findings indicated that the treatment is effective in decreasing the number of roadway departure crashes on rural, two lane roads.
