为减少行人交通冲突、有效避免交通事故，以信号交叉口的调查数据为基础，开展行人与机动车冲突特征和影响因素分析。在高峰时段，运用基于视频的人工观测法采集行人与机动车冲突数据，分析人车冲突的形式与类型。获取交通冲突表征指标，运用FCM聚类分析方法得出各类型交通冲突的严重性和危险度。在此基础上，进一步分析违法率、行人观察行为与行人冲突的相关性，发现违法率与行人交通冲突存在正向线性关系，而行人的观察行为能有效防止交通冲突的产生。

To reduce pedestrian conflicts and avoid traffic accidents,the pedestrian conflict charac-teristics and its influence factors are studied based on the survey data at signalized intersections.At the peak hour,by using the method of video-based observations to collect the conflict data between pedestrians and vehicles,the form,causes and types of the pedestrian conflicts are analyzed.The in-dicators of traffic conflict are collected,and the fuzzy C-means clustering method is used to obtain the severity and risk of different types of traffic conflicts.In addition,the correlation between viola-tion rate and pedestrian conflicts and the correlation between observing behavior and pedestrian con-flicts are also studied.It is found that there is a positive linear relationship between violation rate and pedestrian conflicts,and the pedestrian's observing behavior can effectively avoid the occurrence of traffic conflicts.
