摘　　要：文章在综述国内外对交通冲突领域研究的基础上,详细地介绍了冲突数据的采集方法,并结合录像观测,对公路平交口的一般冲突和严重冲突的冲突距离及冲突速度进行了数据采集,导出了冲突时间数据,通过分析冲突时间累积频率分布柱状图,对交通冲突的严重性判定进行了研究。最后选择了10个公路平交口,对得出的结论进行了假设检验。This paper introduces the method of gathering data of traffic conflict in detail on the basis of analyzing the present research situation of the traffic conflict at home and abroad. Then some useful data such as the distance and the speed of the vehicle when the conflict occurs are obtained through video recording observation and the time to collision is also gained. The paper also does some research on the severity of the conflict at highway intersections according to the cumulative percentage of the time to collision. Finally, 10 highway intersections are chosen to carry out the supposition examination.
