平面交叉口设计构造“立体交通”——南宁市平面交叉口交通渠化应用

At-Grade Intersection Design Constructs Inter- change Traffic

平面交叉口是道路通行能力与交通安全上的卡口。为了消除交叉口在道路网的“瓶颈”效应,通过应用展宽式信号灯管理平面交通渠化的工程技术,达到提高道路交叉口的通行能力和提高道路网运输效率的目的。南宁市的实践证明,合理的交叉口交通渠化设计是治理交叉口拥堵的一种投资少、效果好的方法。

At-grade intersection is a node of road capacity and traffic safety.To dispel the bottle neck effect of at-grade intersection in the road network,by applying the engineering technology of traffic signal control manage and at-grade intersection traffic channelization, can gain the ends that improving the road capacity of at-grade intersection and increasing the transportation efficiency of the road network.The practice of Nanning city proves that logical at-grade intersection traffic channelization design is a less investment and good effect method to father the traffic jam of at-grade intersection.
