Simulation of Fire emergency evacuation in a large-passenger-flow subway station based on the on-site measured data of shenzhen metro

Abstract Because of its large capacity, high efficiency, and energy savings, the subway has gradually become primary mode transportation for citizens. A density passengers exists within a large-passenger-flow station, number casualties injuries during fire emergency is substantial. In this paper, Pathfinder software on-site measured data Pingzhou station in Shenzhen were utilized to simulate evacuation station. The Required Safe Egress Time (RSET), passengers, flow rates stairs escalators analysed three scenarios: train fire, platform hall fire. time which was 1173 s, longest, 3621 occupants needed evacuate when fully loaded. Occupants could not complete 6 mins all scenarios, does meet currently standards requirements codes. By changing evacuation, rate capacity explored, have reference values safety management plan optimization peak hours operation.
