高速公路连续下坡路段运行速度协调性评价分析

Analysis of the Consistency of Operating Speed Assessment on Continuous Long Downgrade Section of Freeway

针对高速公路长大连续纵坡路段平、纵线形及其组合特性,在检查现行《公路项目安全性评价指南》中关于运行速度协调性评价方法所存在问题的基础上,对高速公路长大连续下坡路段运行速度协调性进行了深入分析,并提出了高速公路长大连续下坡路段运行速度协调性的评价方法,以为设计部门对长大连续纵坡路线运行速度协调性评价提供参考。

This paper systematically analyses the consistency of operating speed on continuous long downgrade section of freeway in connection with horizontal and vertical alignments combination and its characteristics,based on examining the problem about evaluation methodology of the consistency of operating speed in Guidelines for Safety Audit of Highway.Also advance a evaluation methodology for freeway to make a reference for design department.
