The invention discloses a method for analyzing traffic accident risk of a highway tunnel group. The method comprises the following steps of: 1, analyzing traffic environment and accident data of the highway tunnel group; 2, collecting, processing and integrating traffic accident multi-source data; 3, analyzing the traffic safety performance situation; 4, establishing a tunnel group traffic accident analysis model and analyzing risk factors; 5, taking measures related to the accident risk; 6, carrying out the visual display of the accident risk early warning. and 7, giving pertinent precautionary measures and suggestions. According to the method, the multi-source data of the traffic accidents of the highway tunnel group are analyzed and fused, and the analysis model and the Bayesian network model of the traffic accident risk type are established based on the fused data, so that risk early warning is provided for the traffic accident risk factors of the tunnel group for visual display; traffic accidents of the tunnel group can be prevented, targeted measures can be taken, and the traffic accident rate of the tunnel group is greatly reduced.
