Study on crowd evacuation in subway transfer station fires based on numerical simulation

Year: 2022

Type: article

Abstract: In order to study the influencing factors of fire evacuation bottleneck and evacuation time in subway transfer station, a subway transfer station model was built by Pathfinder to simulate the emergency evacuation of passengers in fire. Using the control variable method, the evacuation under different conditions is simulated by changing the parameters. The effects of the use of escalators, the speed of escalators, preference for stairs and escalators,the use of escalators, the familiarity of exits, the speed of personnel movement and the width of stairs on evacuation time are discussed and analyzed. The results show that the fire evacuation bottleneck of subway transfer station is each stair entrance. Evacuation time can be shortened by increasing the speed of escalators, increasing the proportion of escalator walkers, reducing the proportion of passengers who choose familiar exits to escape, increasing the speed of passengers and increasing the width of stairs.
