摘　　要：为了对环形交叉口出口道的机非冲突进行准确判定,利用视频轨迹追踪软件Tracker,提取出口道机动车与过街电动自行车的冲突交通流轨迹数据,选取减速度判别法作为交通冲突发生的判定标准,利用间隙接受理论中的Raff法确定减速度的临界值,并对南京市鼓楼广场环形交叉口的冲突进行机非冲突判别,得到判别结果。In order to accurately determine the noncollision of the exit lane of the roundabout,this paper uses the video trajectory tracking software Tracker to extract the conflict traffic flow trajectory data of motor vehicles and electric bicycles crossing the street,selects the deceleration discrimination method as the criterion for determining the occurrence of traffic conflicts,and uses the Raff method in the gap acceptance theory to determine the critical value of deceleration.The conflict at the roundabout of Gulou Square in Nanjing was judged by chance,and the discrimination result was obtained.

关 键 词：环形交叉口 交通冲突判别 Raff法 减速度
