                Developing Crash Modification Factors for Wrong-Way-Driving Countermeasures

              Abstract:This report documents the evaluated safety effectiveness of wrong-way-driving (WWD) crash countermeasures at freeway ramps and frontage roads. This study focused on the safety effectiveness of geometric features, access management strategies, and traffic control devices (TCDs) from various sites in Texas and in Florida. The analysis found statistically significant crash modification factors (CMFs) for each countermeasure type. The economic evaluation of the countermeasures determined moderate B/C ratios with values greater than 1.0. These study results may be of interest to roadway safety professionals, State and local engineers, and planners responsible for the design, operation, and maintenance of facilities that may have crash risks for WWD.
