A Model For Better Crosswalk Safety, Miguel Figliozzi

TREC Project Briefs

NITC researchers from Portland State University developed models to find what factors affected vehicles’ compliance with pedestrian safety laws.

The results suggest that treatments discouraging accelerating toward a crosswalk could help increase pedestrian safety.

Modeling And Analyzing The Impact Of Advanced Technologies On Livability And Multimodal Transportation Performance Measures In Arterial Corridors: Phase 2, Miguel A. Figliozzi, Chawalit Tipagornwong

TREC Final Reports

Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood.When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In particular, pedestrians can be highly vulnerable at unsignalized, marked crosswalks where pedestrians have the right of way but where drivers’ yield rates are significantly lower than at signalized intersections. Pedestrians are …
