摘　　要：为减少人车冲突及其带来的交通安全隐患问题,对不同用地类型的交叉口右转机动车与行人之间的冲突进行研究。基于视频得到人车冲突数据,通过模糊C均值聚类方法分析不同交叉口冲突严重程度与冲突原因。通过冲突聚类分析发现,不同用地类型的交叉口冲突发生原因和严重程度各不相同。其中,生活区交叉口行人到达无规律,且路口尺寸较小,其严重性冲突占33.3%。In order to reduce the conflict between pedestrians and vehicles and the hidden danger of traffic safety,this paper studies the conflict between right-turning vehicles and pedestrians at different land-use intersections.Based on the video data of pedestri⁃an-vehicle conflict,the paper analyzes the conflict severity of different intersections by fuzzy C-means clustering method,and further studies the causes of each type of intersection conflict.Through the cluster analysis of the conflicts,it is found that the causes and se⁃verity of the conflicts are different at different land-use intersections.The results show that 33.3%of the intersections in the living area are serious conflicts,which are higher than those in the commercial area and the school district.
