Urban road interchange type selection based on Multiple Attributes Decision Making

The issue of urban interchange type selection was discussed by using multiple attributes decision making (MADM). A theoretical model was proposed for interchange type selection based on MADM Method and procedure of comparative alternative (corresponding to Pareto solution of MADM) generation was detailed based on capacity analysis and alternative improving. Considering deciders and engineers´ partial favoritism information about evaluating indexes, a Q-operator T was introduced, the vertical matrix E was obtained based on graphic theory. In addition, the weighted utility matrix of every alternative was acquired for alternative ranking. Finally, the model was applied to one real interchange reconstruction work in Shanghai China. The results indicate that MADM can solve the problem of urban interchange type selection reasonably.
