Safety assessment of signalized intersections through modeling pedestrian-vehicle conflicts

This study aims at developing a methodology for safety assessment of signalized intersections by focusing on the conflict between pedestrians and vehicles. Based on the field data collected by video cameras at a number of signalized intersections, vehicle and pedestrianbehavioral models have been established, which can reasonably represent user speeds, trajectories andtheir interactions under various layouts and operations of signalized intersections. The proposed methodology enables to evaluate the effects of improvements in the geometric layouts and operations of signalized intersections on the safety performance prior to implementation.
