城市立交选型的多指标决策方法

Urban interchange configuration selection based on multiple attribute decision making

采用多指标决策理论对城市立交的选型问题进行了数学解析,构建了立交选型的多指标决策模型框架;结合多指标决策理论,从理论层面探讨了立交备选方案的选择、确定方法,并提出了相应的理论方法——基于通行能力的方案改进法;结合上海市某立交改造工程,采用多指标决策理论对其进行了选型分析.

The issue of urban interchange configuration selection was discussed by using Multipie Attribute Decision Making （MADM） , and also the theoretical frame of interchange configuration selection based on MADM was formed. Referencing to the basic theory of MADM, the method of selecting the comparative scenarios was discussed and formed into theory： Scenario Improving Method Based on Capacity Analysis. Finally, MADM was introduced into one real interchange reconstruction in Shanghai. The result indicates that MADM can solve the urban interchange configuration very well.
