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.

本研究旨在建立一套以人车冲突为主要特征的信号交叉口安全评价方法。基于多个信号交叉口的摄像机采集的现场数据，建立了车辆和行人行为模型，该模型能够合理地反映不同信号交叉口布局和运行方式下的用户速度、轨迹及其相互作用。所提出的方法能够评估的几何布局和信号交叉口的安全性能的实施前的操作的改进的效果。
