浅谈北环立交改造总体方案研究

Brief Discussion on Overall Reconstruction Scheme of North Ring Interchange

北环立交为内环快速与渝武高速相交节点,立交形式为标准的高速公路全苜蓿叶型立交,已营运多年,立交通行能力已不满足现有交通量的需求,拥堵现象突出。改造总体思路为按照城市道路标准提升主线通行能力,消除全苜蓿叶型立交的交织问题,结合主要交通流向新建定向匝道,提高立交的整体通行能力和运行效率,缓解交通拥堵问题。

As an intersecting node of Inner Ring Expressway and Yuwu Expressway,North Ring Interchange is a standard full clover-leaf interchange of expressway.It has been in operation for many years,and its traffic capacity has hardly met the demand for current traffic volume,which causes severe congestion.The overall idea of its reconstruction is to improve the traffic capacity of the main line in accordance with the urban road standards in order to eliminate the weaving problems of the full clover-leaf interchange.By building the new directional ramps in accordance with the main traffic flow,the overall traffic capacity and operation efficiency of the interchange are improved,and the traffic congestion is relieved.
