A novel approach for safety assessment at unsignalized intersections: Integrating spatial metrics into postencroachment time analysis under heterogeneous traffic conditions

Integrating spatial variables in PET analysis provides a more robust measure for conflict analysis and assessment of potential traffic conflicts at unsignalized intersections. The subsequent validation of the model with actual crash data highlights its practical applicability in enhancing road safety. The findings from the study provide a promising direction for future research and the potential for widespread implementation in traffic management systems.
