城市建成区快速化道路立交设计——以上海市虹梅南路中环线立交总体方案设计为例

A Design of Expressway Interchange in Urban Built-up Area: with a Case of the General Plan Design of the Mid-ring Interchange, Shanghai South Hongmei Rd.

城市建成区的快速路立交属中心城交通和环境的敏感区,对其改造存在着诸多限制。以上海中心城区徐汇区的虹梅南路中环线立交总体方案设计为例,通过环境影响评价、交通量预测和交通仿真分析等手法对周边地区的整体交通进行分析,从而确定城市建成区快速路立交工程的方案,为其他建成区的立交设计提供参考。

Located in urban built-up area and limited to urban space, the expressway interchange reconstruction is facing many obstacles, belonging to the sensitive area of the downtown traffic and environment. Taking South Hongmei Rd. Mid-ring general plan design of the downtown Xuhui Area, Shanghai for example, the interchange research of urban built-up area is made. The surrounding general traffic is analyzed by environmental influence evaluation, traffic volume prediction and traffic simulation, and then, the recommended plan of the interchange is determined, which can provide references for similar projects in other built-up areas.
