Study On Urban Rail Transit Operation Safty Assessment System

In recent years, China’s rail transit operating mileage increases rapidly, but the securitysituation is increasingly grim faced. It is necessary to establish a set of practical evaluationsystem and evaluation method, which can effectively identify rail transit weaknesses and risk,and then suggest improvements to ensure the security and operational quality of urban railtransit operators.At first, the paper summarizes the urban rail transit system operating mode and fault typeof failure, on this basis, established the rail transportation section as the basic elementEvaluation Model, Proposed the concept of global and local indicators.And with reference to domestic and foreign literature, rail transportation as a criterion layermanagement, electricity, electronics, vehicles, civil engineering, environmental indicatorsystem, and given the weight of each index using the analytic hierarchy process.Secondly, the paper based on the reference “the subway operator safety evaluation”criteria evaluation content, given the content of the evaluation of each indicator, eachoperating mode of the system is divided indicators attributes. According to the combination ofqualitative and quantitative methods, the maximum safe score was given for theevaluation content.. In accordance with the safety check list method and comprehensiveassessment method, gives the synthesis method of the system safety, divides the systemrisk grade standard.Finally, Section and risk grade was evaluated through comprehensive rating, and then acity rail transit lines were evaluated in accordance with the evaluation system.
