Safety Evaluation and Analysis of Urban Rail Transit Operation Based on DEA

Changfeng Zhu

Abstract

The index structure system of urban rail transit is analyzed and optimized by applying information entropy,and a safety evaluating C2R model on analyzing urban rail transit is set up based on DEA.Finally,a case study of Guangzhou Metro Line 1 is carried out,and annual relative validity of subway operation safety is evaluated by using the Matlab software program.According to the results of the calculation,and in invariable circumstances of output indexes,the input indexes of non-DEA effective decision making units are adjusted.At last,the conclusion according to the front real analysis and suggestions as well as the countermeasures are elicited.
