Urban rail transit station emergency evacuation capability assessment system

Abstract

The invention provides an urban rail transit station emergency evacuation capability assessment system, and relates to the technical field of urban rail transit operation management. The system comprises a station infrastructure management subsystem which generates a station topological structure and stores the generated station topological structure; an evacuation network generation subsystem which determines the station infrastructure passage capacity according to the station topological structure and generates an evacuation network; a feasible evacuation path generation subsystem which calculates and generates a feasible evacuation path according to the passage capacity of each infrastructure in the evacuation network and the walking time of each path; and an evacuation capability assessment subsystem which simulate the evacuation path, selects assessment indicators and displays the assessment indicator result. Accurate assessment of the station emergency evacuation capability can be realized through equilibrium allocation in the passenger flow evacuation network so that data guidance can be provided for passenger flow evacuation induction, the utilization rate of the station infrastructures can be enhanced, equilibrium utilization of the infrastructure resources can be realized and the evacuation efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit operation management, in particular to an emergency evacuation capability evaluation system for urban rail transit stations. Background technique [0002] Most urban rail transit stations are relatively closed underground spaces. In the event of an emergency, the personnel in the station should be transferred to a safe area in the shortest possible time to avoid casualties. The strong emergency evacuation capacity of the station is to protect people Prerequisite for safe and rapid evacuation. Only by ensuring the balanced use of emergency evacuation facilities at the station, so that each facility can bear the minimum evacuation pressure as much as possible in a unit time, can the bottleneck blockage in the evacuation process be reduced and the evacuation efficiency can be guaranteed. Therefore, it is of great significance to correctly evaluate the evacuation capacity of the station un...

AI Technical Summary

Problems solved by technology

Otherwise, the selection of the local optimal path in the evacuation process still has a certain gap with the actual emergency organization, and there are situations where the effective path is not allocated or the flow is unreasonable, resulting in excessive use of the evacuation capacity of the critical path and reducing the evacuation efficiency
