武汉市姑嫂树立交上桥匝道的选型研究

Study on Selection of Upper Ramp for Gusaoshu Interchange in Wuhan

从节点流量、立交用地条件等方面对武汉市姑嫂树立交现状进行分析论述。基于现状分析筛选匝道线位,并提出两个比选方案。从交通评价、与周边建筑物距离、与天然气管道距离等方面进行比选,得出最合适的匝道上桥方案,对立交节点进行微改造,达到缓解拥堵、提升路网运行效率的目的。

The present situation of Gusaoshu Interchange in Wuhan is analyzed and discussed from the node flow and land conditions for the interchange.Based on the present situation,the ramp lines are analyzed and screened,and two selection schemes are put forward and selected from the traffic evaluation,the distance from the surrounding buildings and the distance from the natural gas pipeline in order to achieve the best scheme of upper ramp.The nodes of interchange are slightly reconstructed to obtain the purpose of relieving the traffic congestion and improving the operation efficiency of road network.
