Application of multi-level extensible method to urban subway operation safety evaluation

Abstract

The safety evaluation index system of subway operation is established on the basis of the characteristics of subway operation and the stipulations specified in the national subway construction and operation laws and regulations of our country. In order to make up for the deficiencies of the present subway operation safety evaluation method, the multi-level extensible evaluation model for subway operation safety is developed with the extension method as the core. One line of the Beijing Subway is studied as an example. The risk degrees of the line and its subsystems are determined. Countermeasures are proposed to prevent accidents in subway operation. A new method for comprehensive evaluation of subway operation safety in China is put forward. Theoretical analysis and case study indicate that the new method is applicable to subway operation safety evaluation and it provides reference in further deep research of subway operation safety evaluation in our country.
