重庆中心城区南滨路分流道方案研究

Research on the Diversion Lane Scheme of Nanbin Road in the Downtown of Chongqing

重庆南滨路位于重庆市中心城区核心区,现状交通运行压力较大,但纵向分流通道缺失,因此建设南滨路分流道十分必要。首先,介绍南滨路的建设和交通运行现状,分析现状存在问题,提出相应优化对策。在此基础上,从方案概况、竖向设计、接线设计等方面详细地阐述南滨路分流道方案。最后,运用交通仿真软件对方案分流效果进行评价,结果显示南滨路分流道方案能较好地分流南滨路过境交通,降低南滨路的交通拥堵水平。研究对于城市核心区滨江路分流系统的建设具有一定的指导作用和实践意义。

Chongqing Nanbin Road is located in the core area of the downtown of Chongqing.The current traffic operation pressure is relatively high,but there is a lack of longitudinal diversion channels.Therefore,it is necessary to construct Nanbin Road diversion lanes.Firstly,introduce the construction&transportation operation status of Nanbin Road,analyze the existing problems,and propose corresponding optimization strategies.On this basis,the Nanbin Road diversion lane scheme is elaborated in detail from the aspects of scheme overview, vertical design, wiring design, etc. Finally, the traffic simulation software is used to evaluate the diversion effect of the scheme, and the results show that the Nanbin Road diversion lane scheme can effectively divert the transit traffic of Nanbin Road and reduce the traffic congestion level of Nanbin Road. The research has a certain guiding role & practical significance for the construction of the Binjiang Road diversion system in the urban core area.
