Research on evolutionary model of urban rail transit vulnerability based on computer simulation

Abstract

In order to overcome the vulnerability of the effect of large passenger flow, an improved method based on the vulnerability of large passenger flow was proposed, and 5-year (2013–2017) passenger flow techniques are applied. The urban rail transit safety vulnerability simulation model mainly has three modules. Module 1: Urban rail transit can respond to disturbances in time and make corresponding adjustments and adaptations. Module 2: Urban rail traffic can be restored to a completely normal state for certain disturbances. Module 3: Urban rail transit can be completed within a limited self-recovery and adjustment time, and the fragile state after disturbance can be restored to normal state in time. This section of urban rail transit safety vulnerability evolution model is the core of the algorithm is studied, and according to the model to design the best algorithm procedures, specific algorithm to run the program is shown in Fig. 1. The results of this paper can be used as a basis for solving safety problems. It can in turn help to avoid or reduce the occurrence of disasters and to ensure the safe, fast and efficient operation of subway. This work has significance in theory and practice.
