山区城市道路自救车道设计要点分析

Analysis of Design Key Points of Urban Road Self-Rescue Lane in Mountainous Areas

以贵州省德江县城至马鹿岩大道工程设计为例,根据道路纵坡设置情况、项目区域道路规划,结合运行速度分析,提出自救车道的设置位置。就自救车道设计展开论述,明确城市道路自救车道设计的基本思路,以期为我国山区城市道路自救车道设计提供一定的参考经验。

Taking the engineering design of Dejiang County to Maluyan Ave.in Guizhou as an example,the location of self-rescue lane is put forward according to the situation of longitudinal slope setting,regional road planning and operation speed analysis.This paper discusses the design of self-rescue lane,and clarifies the basic ideas of urban road self-rescue lane design,in order to provide some reference&experience for urban road self-rescue lane design in mountainous areas of China.
