Evaluation of Urban Rail Transit Line Operational Safety Based on Combination Weighting Method

Man Li

Abstract

Based on an analysis of urban rail transit line operational safety,the line operational safety evaluation index system of urban rail transit is established,the meanings and calculation methods of indexes are studied and the line operating safety grade of urban rail transit is delimited.The line operational safety indexes of urban rail transit is evaluated with the method of analytic hierarchy process(AHP) and entropy method combination weights,which accords with system integrity.Beijing metro Line 4 is evaluated as an example to verify the rationality and reliability of this method.And it provides theoretical basis for operational safety decision-making and safety control measures of urban rail transit.
