城市道路交叉口交通改善要点与案例分析

随着我国城市道路交通量的不断增长，城市道路交叉口交通拥堵现象越来越普遍。本文在示例道路交叉口调研的基础上，选取典型性路口从渠化、信号控制、交通组织等方面，分析城市道路交叉口存在的主要问题，结合路口道路断面、用地、交通特性，提出路口控制、渠化、交通组织改善措施，并以十字交叉口交通改善为实例，提出了在不进行道路工程改造的前提下交叉口交通改善要点及措施。

With the continuous growth of road traffic volume in urban areas in China, traffic congestion is becoming more and more common. In this paper, based on the studies of road intersections, a typical intersection is selected to analyze the main problems at the urban road intersection. The paper analyzes these problems from the aspects ofchannelization, signal control, traffic organization and so on, then puts forward road junction control, channelization and traffic organization improvement measures, combining with the road cross section, land use and traffic characteristics. The paper, using the improvements at an intersection as an example, illustrates the key points of intersection improvement and measures, in which road engineering reconstruction is not involved.
