天目路立交的功能与形态解读

To Interpret Function and Morphology of Tianmu Road Interchange

该文以上海南北高架天目路立交为例,提出了立交分析和优化设计的一种方法,即:根据周边条件及现状流量流向,分析立交各个部分所承担的主要交通功能及交通拥挤原因。在此基础上,按照主要承担功能对立交形态进行简化分解,每类交通功能以其典型形式画出草图,通过匝道形式的组合和变换得到满足功能和需求的立交优化方案。

Taking Shanghai South-north Elevated Tianmu Road Interchange as an example, the article puts forward a method of the interchange analysis and optimization design: Based on the present conditions of surrounding traffic flow, it is to analyze the main traffic function undertaken by the various parts of the interchange and the traffic jam reason. On this basis, the article simplifies and breaks up the interchange morphology according to the main undertaken functions. The draft is drawn for each traffic function and its typical type. The optimized scheme of the interchange meeting the functions and demands is given by the combination and changing of the ramp form.
