Set Pair Analysis for Mass Rapid Transit Grey Model Selection

The mass rapid transit system is essential both to rational utilization of the economical resource and optimization of overall arrangement of urban land use. Choice models diffusely used in China now, are largely based on the certain values which fall short of the practice. In this passage, grimy numbers are used to estimate the practical situation and the set pair analysis is introduced to determine the best choice. The example of Yangzhou city in China is taken to validate the feasibility of the model. Based on the indices' values it, which are derived from the data collected by investigation and calculated by Delphi method and indices' Weights decided by the AHP, the decision-making matrix is established to acquire the set pair potential which can determine the rank of the options to be chosen. BY calculation, among three choices (Sub way, LRT, BRT), BRT model which has the highest potential is finally adopted in the city.
