随着城市规模的不断扩大,现有的交通路网尤其是交通节点往往不能满足日益增长的交通需求,成为交通转换的“瓶颈”。论文依托宜昌市胜利三路与东山大道立交改造工程,从方案控制条件、功能定位出发,提出多个立交改造方案,并对各个方案进行综合比较,力求为类似立交改造工程方案研究提供参考。
With the continuous expansion of the city scale, the existing traffic network, especially traffic nodes, often can not meet the growing traffic demand and become the “bottleneck” of traffic transfer. Based on the project of the interchange between Shengli 3rd Road and Dongshan Avenue, Yichang City, this paper proposes several plans for the improvement of the interchanges from the control conditions and functions of the schemes, and makes a comprehensive comparison of the schemes so as to provide reference for the researches on similar interchange schemes.
