摘要
针对兴义环城高速公路项目终点接线位置与原兴义西互通重叠的问题,为了同时满足兴义环城高速与汕昆高速之间交通转换,以及地方道路上下高速的功能需求,须对兴义西互通进行改造。从优化路网节点出发,因地制宜地提出了3个不同形式的互通改造方案,综合比较分析后得出最优推荐方案。
In terms of the problem that the end connection location of Xingyi Ring Expressway overlaps with the original Xingyixi interchange,which needs to be reconstructed,to meet the traffic conversion between Xingyi Ring Expressway and Shantou-Kunming expressway,as well as the functional requirements of local roads up and down the expressway. Starting from the optimization of road network nodes,three different forms of interchange reconstruction schemes are proposed according to local conditions,and the optimal one is obtained after a comprehensive comparison.
