Embodiment 1

[0070] A multi-level subway operation safety risk measurement method, such as figure 1 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 spherical test or the KMO (Kaiser-Meyer-Olkin) test to conduct a 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, using the reciprocal of the index to positively process 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] Among them: Z ij is the original evaluation index, x j is the value of the i-th period of this level, x j...

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 in particular relates to a multi-level subway operation safety risk measurement method. Background technique [0003] As a key member of the comprehensive transportation system, the subway plays an important role in alleviating the pressure of urban traffic and provides a strong driving force for 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 requirements for the safety management of the subway operation are getting higher and higher. A few days ago, the state proposed a dual preventive working mechanism for risk management and control and hidden danger investigation and treatment for safety production work. The "dual control" mechanism also pointed out a new development direction for th...
