Gray Clustering Method Applied to Evaluation of Urban Public Transport Development Level

Aiming at the problem on evaluation of urban public transport development level(UPTDL) which is difficult to resolve with an objective,comprehensive and precise way,The paper describes measurement index system and builds up a multi-layer measurement index system structure for UPTDL.A mathematic model for comprehensive evaluation of UPTDL has been established by means of gray clustering analysis method.Applying the evaluation model,the paper evaluates the development level of Qing-Dao city public transport.The demonstrative analysis illustrates that evaluation results suit to the opinion poll results of development level of Qing-Dao city public transport.The method raises the evaluation efficiency.Thus,the quantitative evaluation method about the UPTDL is developed.
