摘　　要：研究高速公路交通事故风险重要度并进行排序,对提高风险控制效率,减少交通事故的发生的重复性具有重要意义。为获得风险全面且客观的排序,首先应用人因分析及分类模型确定道路交通安全风险及分类,构建道路交通风险网络模型;然后以网络中心性为指标,建立改进的TOPSIS方法(PPR-TOPSIS)对网络中的风险综合排序。运用此法分析京港澳高速公路衡阳段“6·29”重大道路交通事故,并与熵权TOPSIS法对比,结果表明:疲劳驾驶对事故影响最大,贴近度超过80%,企业及运管局的监督管理因素对事故影响较大,贴近度超过50%,PPR-TOPSIS比熵权TOPSIS法更具有综合性与准确度,更适用于重大交通事故。Studying and ranking the risk importance of highway traffic accidents is of great significance for improving the efficiency of risk control and reducing the repetition of traffic accidents.In order to obtain a comprehensive and objective ranking of risks,firstly,the human factors analysis and classification system(HFACS)model was applied to determine the road traffic safety risk and classification,and the road traffic risk network model was constructed.Then,taking network centrality as the index,an improved TOPSIS method(PPR-TOPSIS)was established to comprehensively rank the risks in the network.The proposed method was used to analyze the“6.29”major road traffic accident in Hengyang section of Beijing-Hong Kong-Macao Expressway and compared with entropy weight TOPSIS method.The results show that the influence of fatigue driving on the accident is maximum,whose closeness is more than 80%;and the influence of supervision and management factors of both enterprises and TBA is relatively larger,whose closeness is more than 50%.And PPR-TOPSIS method is more comprehensive and accurate,which is more suitable for major traffic accidents.
