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.

    本发明公开一种高速公路隧道群交通事故风险的分析方法,包括步骤一、对高速公路隧道群交通环境和事故数据进行分析;步骤二、采集交通事故多源数据并进行处理和集成;步骤三、交通安全性能态势的分析;步骤四、建立隧道群交通事故分析模型并分析风险因素;步骤五、提出事故风险相关措施;步骤六、对事故风险预警可视化展示;步骤七、针对性防范措施和建议;本发明通过对高速公路隧道群交通事故的多源数据进行分析融合,并基于融合后的数据建立分析模型和交通事故风险类型的贝叶斯网络模型,从而实现对隧道群的交通事故风险因素提出风险预警进行可视化展示,可以对隧道群交通事故进行防范和采取针对性措施,大大降低隧道群的交通事故发生率。
