中心城区快速路选线研究

Study on Expressway Alignment in Central Urban Areas: A Case Study of Caobao Road Expressway

摘要:

快速路通道线位的合理性，直接影响到项目交通功能的发挥及区域路网的整体运行效率。在城市建成区，特别是超大城市中心城区，如何选取合理的快速路通道路由需应对诸多复杂的控制因素。以上海市漕宝路快速路选线为工程依托，通过比选其不同的线位系统，从交通功能影响、城市用地与风貌影响、轨道交通影响、铁路走廊影响、施工组织影响等维度进行综合评价，确定了兼顾交通功能与社会环境效益的最优选线方案。研究成果可为类似的中心城区快速通道项目选线提供有益参考。

Abstract:

The rationality of expressway alignment directly affects the fulfillment of project traffic functions and the overall operational efficiency of the regional road network. In built-up urban areas, especially in the central urban areas of megacities, how to select a reasonable expressway route must address numerous complex controlling factors. Based on the alignment selection of the Caobao Road Expressway in Shanghai, by comparing its different alignment systems, the comprehensive evaluation is conducted on the influences from the multiple dimensions of traffic function, urban land use and landscape, rail transit, railway corridor and construction organization. An optimal alignment scheme that balances traffic function and socio-environmental benefits is determined. The research findings can provide a useful reference for alignment selection of similar expressway projects in central urban areas.
