Abstract:The goal of this research effort was to identify strategies to mitigate wrong-way driving (WWD) incidents on arterials in Florida by developing a scenario-based WWD crash mitigation approach to address two specific needs: which arterial corridors are prone to WWD incidents and which WWD incident category needs addressing on these corridors. The WWD crash data analysis was based on five years of crash data from 2012-2016. During the analysis period, a total of 2,879 crashes were identified as potential WWD crashes on state-maintained non-limited access facilities in Florida. Police reports of these 2,879 crashes were reviewed in detail. Of the 2,879 potential WWD crashes, only 1,890 crashes (i.e., 65.6%) were categorized as actual WWD crashes resulting from vehicles traveling the wrong way. Most of these WWD crashes occurred at night, and over 50% occurred at or near intersections. On average, nearly 7% of all WWD crashes on non-limited access facilities resulted in a fatality, and 52.5% resulted in an injury. A Geographic Information System (GIS)-based spatial clustering analysis was used to identify top 10 WWD crash hotspots within each FDOT District, based on the number of WWD crashes and the Equivalent Property Damage Only (EPDO) scores. A detailed analysis was conducted to identify specific roadway geometric and demographic factors contributing to WWD crashes at the WWD crash hotspots in each FDOT District. For each WWD crash hotspot in each district, one or more of the following roadway geometric and demographic factors that contributed to WWD crashes were identified: one-way streets; signalized intersections; stop-controlled intersections; absence of WWD signs; impaired drivers; and/or drivers age 65 years and older. Moreover, critical signalized and stop-controlled intersections along all the state roads within each of the WWD crash hotspots were identified. The study results help shape near-term and long-term planning and policy directives for mitigating WWD incidents on non-limited access facilities.
