Efficiency evaluation is one of the major issues in urban
transportation. Since the efficiency of the systems is affected by its data and output, what makes the results of the performance evaluation valid and applicable, is selecting the appropriate data and outputs of the system. In this study, the efficiency of the subway stations in Tehran in case of return, compared to the fixed scale, is measured and ranked in a three-year period (2010-2012), by using
data envelopment analysis (DEA)
[1]; that is a non-parametric method for assessing the performance of the units (DMUs)
[2]. Also In this study, by the analysis of the sensitivity of the model, compared to the inputs, their impact on the performance of the stations is examined. The results suggest that, stations of Sadeghiyeh, Shar-e-Rey and Panzdah-e-Khordad, have the highest level of performance and can be used as a proper model for inefficient stations
