山区高速公路线形安全协调度评价

从驾乘人员的角度出发，深入分析山区高速公路线形安全系统各组成要素，选取影响公路线形与安全协调度的指标，并引入群层次分析法建立山区高速公路线形安全协调度评价综合指标体系，且通过统计高速公路设计专家的咨询结果来确定评价指标权重。实例分析表明该方法是可行的，为山区高速公路线形设计进行有效的安全性评价奠定了基础，具有较好的现实意义和应用价值。

Evaluation for Linetype and Safety Coordination Degree of Expressways in Mountainous Area

Starting from the viewpoint of drivers and passengers, this paper deeply analyzes components of linear safety system of highways in mountainous area, selects indicators influencing linetype and safety coordination degree of expressways, establishes a integrated indicator system of evaluation for line type and safety coordination degree of expressways in mountainous area by introducing the analytic group hierarchy process, and determines the weights of evaluation indicators based on statistical consulting results of design experts for expressways. Analysis of examples shows that this method is feasible and lays a foundation for effective safety evaluation for linetype design of expressways in mountainous area and exhibits good practical significance and application value.
