• Abstract:
  This project investigated the extent and characteristics of wrong-way driving (WWD) on Idaho limited access roadways. WWD crash (WWC) counts have been increasing in recent years, especially on I-84 and I-90. A model was developed to identify WWD hotspot segments by predicting WWCs based on non-crash WWD citations, exit design characteristics, traffic volumes, and area type. An optimization algorithm was then utilized to identify specific exits within and outside of the hotspots for optimal deployment of WWD countermeasures. The optimization algorithm identified the 81 optimal exit ramps for countermeasure deployment and was shown to improve WWD reduction by 60% compared to only deploying countermeasures in the hotspot segments. Based on the findings from this project, it is recommended for the Idaho Transportation Department to prioritize deployment of WWD countermeasures at these 81 optimal ramps, consider lighting and signage improvements at exit ramp terminals and crossing streets, install treatments at crossing roads to reduce left-turning WWD vehicles where possible, increase law enforcement presence on I-90 and at nighttime if possible to reduce WWCs, standardize the reporting practices for WWCs and WWD citations, collect WWD dispatch reports throughout the state, and conduct additional research on mainline and construction crossover WWCs.
