Embodiment 1

[0070] A multi-level metro operation safety risk measurement method, such as figure 1 As shown, including the following steps:

[0071] S1. Select the subway operation safety risk evaluation index and determine the calculation method of each index, which may further include the following steps:

[0072] S11. Use the Bartlett sphere test method or KMO (Kaiser-Meyer-Olkin) test method for feasibility test to determine whether the original variables are suitable for factor analysis. If there is no strong correlation between the original variables, then Eliminate the corresponding variables;

[0073] S12: Use the reciprocal of the index to forward the reverse index in the index system;

[0074] S13. Establish a sample matrix and standardize (dimensionless) the sample data. The calculation method is as follows:

[0075] Z ij =(x ij -x j* ) / s j

[0076] Where: Z ij Is the original evaluation index, x j Is the value of the i-th period of the level, x j* X j The sample mean of the indicator, s...

Abstract

The invention discloses a multi-level subway operation safety risk measurement method, which includes: using factor analysis method to select subway operation risk evaluation indicators, determining the calculation and assignment method of each indicator, and establishing a station level-line level-line network level multi-level risk assessment. The indicator system uses the LEC evaluation method to measure and evaluate the risks of subway stations, and then uses the risk evaluation model based on the extension theory to evaluate the station level, line level, and line network level respectively to determine the safety of the overall object and individual indicators. status, provide guidance for risk management and control work, overcome the current problems of scattered evaluation content, unclear service objects, and one-sided evaluation results in the current safety risk evaluation process, realize micro, meso, and macro safety risk evaluation of subway operations, and improve risk Evaluate the accuracy, effectiveness, and operability of the method.

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...
