城市道路交叉口作为城市道路交通的咽喉,是保证城市道路通行能力和交通安全的主要结构,在整个城市交通秩序上都有着十分重要的意义。但是,根据人们的实际调查,城市道路平面交叉路口在实际应用的过程中,不但没有起到保证道路通行能力的效果,反而成为了城市交通堵塞的重点。本文首先对我国城市道路交叉路口交通现状进行分析,其次阐述了当前人们在对城市道路交叉路口的设计原则,讨论了城市道路平面交叉路口合理渠化对道路通行能力的改善,以供相关人士参考。
Urban road intersections, as the throat of urban road traffic, are the main structures that ensure the capacity of urban roads and traffic safety. They are of great significance in the entire urban traffic order. However, according to people’s actual investigation, in the actual application of the urban road intersection, not only does it fail to ensure the capacity of the road, but it becomes the focus of urban traffic congestion. This paper first analyzes the current traffic conditions of urban road intersections in our country, then elaborates the current design principles of urban road intersections, and discusses the reasonable channelization of urban road intersections to improve the road traffic capacity for the reference of relevant parties .
