The invention belongs to the technical field of city expressway traffic management, and particularly relates to a traffic event duration time calculation method based on traffic scene radar. The method comprises the following steps of installing the traffic scene radar in an expressway region to be tested, and debugging and setting a detection range; using the traffic scene radar to obtain positioning data of moving vehicles in the detection region; calculating the running speed of the single moving vehicle in the detection region at one time interval; calculating the average running speed at each road section in the detection region at one time interval; adopting a threshold method for judging the traffic event; calculating the duration of the traffic event. The method has the advantages that the current traffic event duration can be fast obtained, so that a traffic manager can reasonably define the traffic flow division position of the current jamming road, so that the goals of avoiding the occurrence of secondary accidents and traffic jamming and reducing the influence of accidents and the running delay can be achieved, and the event dealing decision level of the traffic manager and the intellectualization level are improved.
