Abstract:
Taking the planning and evaluation of Wuhan city circle rail transit network as a case study, three kinds of planning schemes of Wuhan city circle rail transit network were comprehensively evaluated by AHP and entropy weighted grey fuzzy comprehensive evaluation method with the support of geographical information system (GIS).The subjective index weights were obtained based on analytic hierarchy process (AHP). The objective index weights were determined using entropy method based on quantitative calculations of GIS spatial analysis. Then, the subjective and objective weights were combined to get the final weight matrix for comprehensive evaluation. Membership degree was derived by grey relation analysis, and fuzzy operator was performed between weight matrix and membership.Ultimately, fuzzy evaluation value was determined for each planning transit network scheme. The subjective uncertainty of scheme weight assignment in the evaluation process of rail transit network planning could be improved by applying the method, which could serve for the evaluation and optimization of city cicle rail transit network planning.
