首发时间:2010-07-28
摘要:交叉口是道路系统的重要组成部分,既是道路交通的咽喉,但也是“瓶颈”。存在行车速度低、事故率高、交通拥挤甚至交通堵塞等弊病。针对交叉口交通事故的严重性,提出进行交通组织设计的必要性。本文主要介绍了三种交通组织方法:设置专用车道、左转弯车辆的交通组织、组织渠化交通。并结合具体设计实例对交通组织设计进行进一步的分析和阐明。

Discusses on transportation organization designs of intersection
Abstract:Intersection is an important part of the road system, which is the throat, but also the “bottleneck”. There is a low speed, high accident rate, traffic congestion even traffic jams and other problems.Based on the seriousness of traffic accidents for the intersection, proposed that carries on transportation organization designs necessarily, This paper describes three methods of transport organization: setting specific drive lane, traffic organization of left turn vehicles, organization of channel traffic. Combined with concrete examples of the design traffic for further analysis and clarification.
