The invention belongs to the technical field of city expressway traffic management, and particularly relates to a traffic event influence range 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 detected, and debugging and setting the 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 of the 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; obtaining the influence range of the traffic event. The method has the advantages that the influence range of the current traffic event can be fast known, so that a traffic manager can reasonably define the traffic flow division position of the current jamming road, the goals of preventing the occurrence of the secondary accidents and the jamming and reducing the influence of the accidents and the running delay are achieved, and the event disposal decision level of the traffic manager and the intellectualization level are improved.
