Evaluation of Signs at Highway-Rail Crossings

This project evaluates the safety impacts of replacing STOP signs with YIELD signs at highway–rail grade crossings. The study examines whether this transition has resulted in measurable reductions in crashes and near misses, while also analyzing key crossing characteristics—including traffic volume, train frequency, visibility, and roadway type—that may influence safety outcomes. Findings will be used to provide data-driven recommendations on whether to retain, modify, or reverse the signage change at specific locations, supporting evidence-based decisions for improving transportation safety.
