The fast development of urbanization and development have led to an increase in the difficulties with regards to satisfying the demand of public transport. The quantized evaluation analysis of urban public transport performance is useful to identify its shortcomings and to also enable further optimization of the transport system. This facilitates the improvement of the systems quality of service and provides the means to reduce operating costs. Furthermore, the quantification of the bus lines performance evaluation is crucial in raising the systems operational efficiency and improving the operators level of service. In this study, the data collected from Hangzhou Bus Companys operating income table is evaluated to assess bus performance by Excel and Deap software. The study constructs the conceptual framework that evaluates the performance evaluation of the single bus line, and divides the implementation process of the single bus line service into two stages. Building the Output-BCC (Banker Charnes Cooper) model with DEA method to calculate the operational efficiency and service efficiency, then accesses the Hangzhou bus transport objectively and provides some suggestions,
