基于改进层次分析法的高速公路交通安全评价

摘要

基于道路交通系统特征和交通安全影响因素分析，构建包括道路线形、路基路面、交通安全设施3个1级指标及11个2级指标的高速公路交通安全评价指标体系，并采用改进的层次分析法来确定各指标权重。以模糊理论为基础，建立高速公路交通安全状况模糊综合评价模型，并以广东省汕昆高速公路北斗至清潭段为例，对其交通安全现状进行评价。%Based on analysis for the features of road traffic system and influence factors of traffic safety, this paper establishes an evaluation index system for traffic safety of expressways including 3 class 1 indices,i.e.road linetype,roadbed pavement,traffic safety facility and 11 class 2 indices,and determines the weights of all indices by means of improved analytical hierarchy process.On the basis of fuzzy theory,the paper establishes a fuzzy comprehensive evaluation model for traffic safety of expressways and evaluates the status quo of traffic safety with Beidou -Qingtan section of Shantou -Kunming Expressway in Guangdong as an example.
