| 摘 要： | 高速公路匝道安全问题直接影响整条高速公路乃至区域路网的交通运行效率。为了提高匝道安全性和服务水平，在分析高速公路匝道事故特点和原因的基础上，提出了适用于匝道交通安全的评价指标，并建立了相应的评价体系；采用层次分析法与熵值法相结合的方式确定评价指标的权重，应用模糊评价方法给定综合评价值，同时应用于宁杭高速公路匝道交通安全的综合评价，评价结果与实测数据相吻合。

| Abstract: | Freeway ramp security directly affects the operation efficiency of the whole freeway and even the regional road network.In order to improve the ramp security and service level,this paper analyzes the characteristics of freeway ramp and reasons of accidents.Then,the suitable ramp safety evaluation indexes were presented and an evaluation system was established.Moreover,the AHP and entropy method was used to calculate combination weight,while the fuzzy evaluation method was used to determine the value of comp... |
