Abstract
A quantitative method for the severity of traffic conflict in intersection is proposed. It assumes moving elements as points. By using the video image sequences, the moving parameters of vehicles are obtained. The conflict time is chosen as criterion of the severity of traffic conflict in this paper. The less of the conflict time, the traffic conflict is more serious. The severity of conflict is estimated according to established model and conflict time under the point assumption of moving elements. A case recorded by video is analyzed. The result shows that the model can be used to detect serious traffic conflict. It can be used in analysis of traffic safety in intersection.
