A Study of the Effects of Pavement Widening, Rumble Strips, and Rumble Stripes on Rural Highways in Alabama
The objectives of this study are as follows: 1. Document the state of the practice and results of prior research; 2. Estimate reduction in run-off-road (ROR) crashes, by severity, based on the data, applying both Empirical Bayes (EB) and equivalent property damage only (EPDO) methods; 3. Develop crash modification factors for the following five treatments: Paving 2 to 4 ft of unpaved shoulders on two-lane rural roads; Combined effect of paving 2 to 4 ft of unpaved shoulder and adding rumble strips on two-lane rural roads; Combined effect of paving 2 to 4 ft of unpaved shoulder and adding rumble stripes on two-lane rural roads; Paving 2 to 4 ft of unpaved shoulders on four-lane divided rural roads; and Combined effect of paving 2 to 4 ft of unpaved shoulder and adding rumble strips on four-lane divided rural roads; 4. Quantify the benefits and costs of the Alabama Department of Transportation (ALDOT) policy; and 5. Make recommendations for future application.
