Comprehensive Evaluation Method of Regular Transit System in Small and Medium-sized Cities

In this paper ,an analytic hierarchy process and a fuzzy evaluation method are combined and used to eval-uate urban transit systems of small and medium-sized cities .Firstly a hierarchy-based comprehensive evaluation system is developed ,and then an AHP method is used to determine the relative weight of each indicator .In this process ,SPSS software is used to carry out a cluster analysis of experts'weights ,where those weights which are far away from the resul-ting clusters are removed ,which appears to make the evaluation weights from the experts more reasonable .Furthermore , using a sample of 12 small or medium-sized cities ,the sampling distribution of the indicators of the transit systems of the small or medium-sized cities is developed and the membership function of each indicator is established through the Matlab Fuzzy Toolbox .Finally ,a fuzzy comprehensive evaluation model of transit systems of small and medium-sized cities is proposed ,which is also verified through the transit system of Fuxin City .The model can provide not only a ranking score ,but also the degree of the proximity of the transit system being evaluated to various levels .
