Wrong-Way Driving Solutions, Policy, and Guidance

Since the beginning of the interstate highway system in the 1950s, crashes related to driving the wrong way on freeways have posed a problem for transportation officials. To this day, even though wrong way collisions are infrequent (only about 3 percent of all crashes on high-speed, divided highways) wrong-way driving (WWD) remains a serious problem because the resulting crashes almost always result in death or serious injury to the persons involved. According to the National Highway Transportation Safety Administration (NHTSA) Fatality Analysis Reporting System (FARS) database, nationally 1,566 fatal WWD crashes occurred on divided highways over a 6-year period from 2004 to 2009, resulting in 2,139 fatalities. On average, about 360 people are killed each year as a result of WWD. WWD events continue to occur due to many factors. Many of the approaches so far have accomplished some reductions. New more advanced technologies are forthcoming in the market place and need to be evaluated and included in an overall approach to the problem. The development and compilation of clear guidance into a single document that could be included in DOT design manuals would foster a more systematic and uniform installation of roadway geometries, signs, striping, and technology. A more uniform method for monitoring, measuring, and reporting the effectiveness of these installations would also help in demonstrating the results of the overall program. The objectives of this research are to (1) develop guidance for retrofitting existing interchanges and design of new interchanges to reduce the likelihood of WWD incidents and crashes, and (2) evaluate the potential for active WWD warning technologies that are now becoming commercially available or in development to reduce WWD incidents and crashes.
