摘　　要：为了确定区域道路网络拓扑结构对交通安全性的影响,建立路网结构安全性综合评价模型,针对路网结构形式多变、难以量化的特点,在分析区域高速公路网络结构对交通安全影响的基础上,提取影响区域高速公路网安全性的指标,构建综合评价指标体系,采用集值统计法确定指标权重,并利用模糊综合评价法对路网结构安全性进行综合评价。In order to determine the impact of regional road network topology on traffic safety,a comprehensive evaluation model of road network structure safety was established.Aiming at the characteristics of road network structure which was changeable and difficult to quantify and based on the analysis of the influence of regional expressway network structure on traffic safety,this paper extracted the index of influencing regional expressway network safety,constructed a comprehensive evaluation index system,used set-valued statistics method to determine the index weight,and used fuzzy comprehensive evaluation method to comprehensively evaluate the safety of road network structure.Examples show that the method is feasible.

关 键 词：区域高速公路网 网络结构安全性 交通安全 模糊综合评价法
