Synthetic evaluation for urban rail transit line network planning scheme based on AHP-fuzzy method

Based on study and analyses of the theory of urban rail transit network program, it is indicated that urban rail transit has become more and more important and rail transit line network planning is more significant with the rapid development of transport construction. On this basis, the program decision making assessment by layer index system is established; at the same time, the method of combing AHP and fuzzy is proposed due to the problem of present evaluation methods. The AHP-fuzzy model established in this paper can be used to evaluate a certain city's rail transit line network planning. With an example, it is proved and verified that all the information can be used and theory can be combined with experiences in the AHP-fuzzy model. The results show that they are in conformity with the actual situation of urban rail transit line network planning. It can provide service for the assessment and solution of urban rail transit network program, thus avoiding human errors in policy making.
