客运快速路与货运干道交叉节点的方案设计

Scheme Design of Intersection Node for Passenger Expressway and Freight Trunk Road

无锡市江海西路是规划中心城区与西部新城衔接的重要客运快速通道。在城郊惠山区段,江海西路沿线与S342省道、锡宜高速公路无锡西互通、钱威路三条间距较近的横向干道相交。在江海西路快速化改造工程设计中,该区段客货交通组织较为复杂,江海西路作为客运快速路与货运占较大比例的横向干道形成三处互通立交转换节点。基于不同的货运交通组织方式,设计了两个总体方案与对应的立交节点方案进行优缺点比较。方案一考虑主线服务于客运,货车在各节点处通过地面道路或路网绕行;方案二考虑在该区段增设集散车道兼顾客、货运进行节点交通转换。通过对这种典型案例的分析,总结了客运快速路与货运干道交叉节点的方案设计要点。

Wuxi West Jianghai Road is an important passenger expressway linking up the planned central urban area with the western new town. In Huishan District of the suburb, West Jianghai Road intersects three transverse trunk roads closely located of S342 Provincial Highway, Wuxi West Interchange of Wuxi-Yixing Expressway and Qianwei Road. In the design of the West Jianghai Road Expressway Reconstruction Project,the passenger and freight transportation organization is complex in this area. West Jianghai Road as a passenger expressway forms three interchange nodes with the larger freight proportion of transverse trunk roads. Based on the different freight traffic organization methods, two overall schemes are designed, and the advantages and disadvantages of the corresponding interchange node schemes are compared. Scheme I assumes that the main line serves the passenger traffic and the trucks pass through the ground roads at the nodes or detour the road network. Scheme II considers adding the collecting-distributing lanes in this section for the node traffic conversion of passenger and freight. Through the analysis of this typical case, the paper summarizes the scheme design gist of intersection node for passenger expressway and freight trunk road.
