浅谈市政道路平面交叉口的设计要点
摘要:随着城市化进程的加快,城市的规模也不断扩大,市政道路网也在不断增加。平面交叉口作为市政道路网中最为重要的一个部分,它的功能是连接相交道路,使其构成道路网,使路网中的人和车实现自由转向。交叉路口是道路网络的结点,在路网中起着从线扩展到面的重要作用。平面交叉口又是人流、机动车流与自行车流的汇集点,它们之间的相互干扰,使行车速度降低,出行交通拥挤,甚至交通堵塞。因此,设置合理的交叉口,对于保证行车安全和通行顺畅具有重大的现实意义。本文主要就市政道路交叉口设计相关问题进行了探讨,着重对市政道路平面交叉口的平面设计和立面设计要点进行了探讨。

Abstract: along with the speeding up of urbanization, the city scale is constantly expanding, municipal work is also growing. Plane intersection as one of the most important part of city work, its function is to connect the intersection road, a work, make the people and the car of the work to freedom. Is the intersection of work nodes in work plays a line from the extension to the important role. Plane intersection is stream of people, motor traffic and traffic flow collection point on its own, the mutual interference between them, the lower the driving speed, travel, traffic congestion, and even traffic congestion. The intersection of setting reasonable, therefore, to ensure traffic safety and traffic flow is of great practical significance. This article mainly municipal road intersection design related problems are discussed in this paper, focusing on the municipal road intersection of plane design and the facade design key points are discussed in this paper.
