Simulation Analysis of Urban Rail Transit Station Evacuation Considering Line of Sight Obstruction

摘要

For urban rail transit station simulation evacuation, domestic and foreign scholars for panic, conformity, reason, gender ratio research has been more mature. However, in the actual evacuation process, the line of sight will be blocked due to the block of buildings, no scholars have studied the influence of the obstruction of sight on the evacuation. In this paper, using Anylogic software, an experimental model is established to compare and analyze the influence of line of sight obstruction on evacuation time, taking a subway station in Southwest China as an example, this paper introduces the factor of line of sight obstruction, when setting up evacuation route, it integrates the evacuation distance and exit congestion degree, establishes the dynamic selection model of pedestrian evacuation path, obtains the evacuation bottleneck of the station, and puts forward the evacuation bottleneck of the station Optimize the scheme and shorten the evacuation time of the station.
