地形受限情况下的公路五路交叉口设计方案比选

Comparative Selection of Highway Five-road Intersection Design Plans under Limited Terrain Circumstances

五路交叉口是交通工程设计上的一个难点,公路五路交叉口比城市道路五路交叉口更难处理。文章以城郊结合部的一个典型的公路五路交叉口为例,讨论了若干种设计方案,并从技术可行性和经济合理性上提出方案选择的原则和方法。

Five-road intersection is a difficulty in traffic engineering design,the highway five-road intersection is more difficult to be processed than urban road five-road intersection.Taking a typical subur-ban highway five-road intersection as the example,this article discussed several design options,and proposed the selection principles and methods from the technical feasibility and economic rationality.
