• Abstract:
  The Indiana safety management program targets the reduction of crashes at high-speed, two-way stop-controlled (TWSC) intersections, which are responsible for 8.2% of serious crashes statewide that cause approximately 1,000 serious injuries and over 90 fatalities annually. Key risk factors include human error, high traffic volumes, and high speeds. Despite the implementation of measures, such as alternative intersection designs and enhanced visibility, additional countermeasures are needed to further mitigate these risks at rural TWSC intersections with lower traffic volumes. Intersection Conflict Warning Systems (ICWS) presents a promising solution by alerting drivers to potential vehicle conflicts.
