Risk assessment research used in subway crowded stampede with grey analytic hierarchy process (AHP)

Abstract

In this paper, mathematical model is considered to be used. Evaluation index system is constructed on the basis of analyzing the subway crowded stampede from the people and things, environment and management factors in a large number of objective classifications. The subway crowded stampede modeling analysis and assessment are quantified with grey hierarchical analysis method, concluding that the evaluation results of assessment instance of crowded stampede risk are in intermediate levels. During the process of evaluation instances actual operation, traffic in commuting is huge and passenger transfers of stairs and elevators are very crowded, which has high risk of stampede and need to strengthen the control to prevent crowded stampede. The safety evaluation results are fundamental identical to the actual state. Evaluation analysis results show that grey hierarchical analysis method has certain practicability, which is worth to promoting.
