Geo-Locating and Identifying Wrong-Way Driving Entrance Points in Bexar County Highway System
The research objects to discover the long-term effective solution for Wrong-way Driving (WWD) on highway, which will be economical, convenient, efficient, and realistic. The intense severity of a WWD accident is encouraging the authorities to install a system that will ensure safety for motorists on highway. WWD events are mostly result of intoxicated driving, where the unconscious driver takes the wrong way to place other motorists of same highway segment into life-threatening danger. This research has attempted to explore from basic knowledge of WWD occurrence to examine the origin and driving philosophy of intoxicated drivers from land-use impact and mathematical modeling point of views. To identify the geolocation entrance points of this phenomenon, the research has implemented data from WWD crash database, 911 calls database, and on-premises alcohol serving locations for analysis. Utilizing a proposed methodology to analyze 543 exit ramps inside the Bexar County highway system, 213 ramps have been identified with geolocation that can be considered as the potential hotspots for entrance of WWD. The location database of 213 ramps should help the authorities to apply cost-effective countermeasures to detect WWD in real-time without involvement of accidents. The outcomes of this research will include a methodology for determining WWD entrance locations of a regional highway and a list of WWD entrance hotspot locations of the Bexar County highway system. This list of locations is a result of utilizing the proposed methodology with proper validation.
