The invention discloses a multi-mode integrated traffic abnormal event detection method, and belongs to the technical field of intelligent traffic. The method comprises the following steps: acquiring historical track data and lane information of a road, and video data and radar data of edge equipment; a road traffic flow parameter index data set is obtained through the video data and the radar data, the accuracy of a data source is verified, and the current road congestion state is judged through clustering; identifying and tracking a target through video data, detecting a suspected static target, constructing an abnormal topological graph for the suspected static target, and carrying out accident detection; preferably selecting a traffic flow index to carry out sudden change accident detection; a track thermodynamic diagram is constructed through radar data for accident detection; and outputting the abnormal information of the current road according to the accident detection result. According to the invention, reliable detection of traffic congestion and accidents is realized, the detection rate of traffic events is improved, the false alarm rate is reduced, large data volume can be processed in real time, and the requirements of real-time performance and accuracy of the system are met.
