高速公路增设互通式立交方案比选分析

Comparison and Analysis of Schemes for Adding Interchanges on Expressways

针对城镇化的快速发展导致城市对外交通格局产生变化的问题,依据城市对外交通服务城市发展的设计理念,采用实地踏勘、数据分析、工程方案比选等方法对城市建成区外围高速公路增设互通的技术方案进行了对比分析。从技术分析、交通量预测、工程造价及与城市规划的协调等角度结合既有高速增设互通原则、高速公路的互通布局及城市对外交通需求选出了符合地方实际的最佳方案。

In view of the change of urban external traffic pattern caused by the rapid development of urbanization,based on the design concept of urban external traffic service for urban development,the technical schemes of Expressway Interchange in the periphery of urban built-up area are Compared and analyzed by using the methods of field survey,data analysis and engineering scheme Comparison.From the technical analysis,traffic volume forecast,project cost and coordination with urban planning,combined with the principle of adding interchange for existing expressway,the interchange layout of Expressway and the external traffic demand of the city,the best scheme in line with the local reality is selected.
