The invention discloses a multi-detection-mode traffic event fusion method based on a D-S evidence theory. The method comprises the steps that event data monitored by a radar, event data monitored by a video and event data judged by traffic operation characteristics are acquired; assigning the basic credibility of the event data of the three signal sources to generate a signal source basic credibility distribution table; performing fusion by using a D-S synthesis rule according to the signal source basic credibility distribution table to obtain a fused trust function; and using the D-S evidence theory to make a decision and output a complete event set. According to the method, the video traffic event data, the radar traffic event data and the traffic event data judged by traffic operation characteristic change are analyzed and researched, and a multi-monitoring-mode traffic event automatic monitoring fusion algorithm is provided, so that the efficiency and the accuracy of traffic event automatic monitoring are improved.
