Abstract:

This project explores the possibility of using high-resolution traffic signal data to evaluate intersection safety. ; Traditional methods using historical crash data collected from infrequently and randomly occurring vehicle ; collisions can require several years to identify potentially risky situations. By contrast, the proposed method ; estimates potential traffic conflicts using high-resolution traffic signal data collected from the SMART-Signal ; system. The potential conflicts estimated in this research include both red-light running events, when stop-bar ; detectors are available, and crossing (i.e. right-angle) conflicts. Preliminary testing based on limited data showed ; that estimated conflict frequencies were better than AADT for predicting frequencies of angle crashes. With ; additional validation this could provide a low-cost and easy-to-use tool for traffic engineers to evaluate traffic ; safety performance at signalized intersections.
