A multi-level subway operation safety risk measurement method

Abstract

The invention discloses a multi-level metro operation safety risk measurement method, which comprises the following steps: selecting metro operation risk evaluation indexes by using factor analysis method, determining calculation and assignment methods of each index, and establishing station hierarchy-line level- line network level-multi-level risk evaluation index system of, measuring and evaluating the risk of metro station by LEC evaluation method, and then using the risk assessment model based on extension theory to analyze the risk of the station level, line level, at the network level, judging the security state of the whole object and the single index. The method can provide guidance for risk management and control, overcome the problems of scattered evaluation content, unclear service objects and one-sided evaluation results in the current safety risk assessment process, realize the micro-, meso-and macro-safety risk assessment of subway operation, and improve the accuracy, effectiveness and operability of risk assessment methods.

Description

[0001] Field [0002] The invention belongs to the technical field of subway safety risk management, and specifically relates to a multi-level subway operation safety risk measurement method. Background technique [0003] As a backbone member of the comprehensive transportation system, the subway has played an important role in alleviating urban traffic pressure and provided a strong impetus to urban development. As the scale of the subway network continues to expand, the accessibility and convenience of the subway continue to improve, and the passenger flow of the subway is also increasing day by day, which indicates that the level of safety management for subway operations is becoming higher and higher. A few days ago, the state put forward a dual preventive work mechanism for risk grading management and control and hidden danger investigation and management for work safety. The "dual control" mechanism also pointed out a new development direction for subway operation risk manage...
