Abstract: In the event of a subway train fire, the number and combination of train door openings have a significant impact on evacuation efficiency when using interval personnel evacuation strategies. This article proposes 8 door opening strategies, constructs a personnel evacuation model and verifies it, and conducts comparative analysis based on simulation. The results show that during one-way evacuation, the evacuation efficiency is highest when all doors are opened, which is 57% higher than the end door evacuation and 33% higher than the passenger compartment door evacuation; When all car doors are opened for evacuation, the mobility inside the carriage increases. The number of people evacuated through carriage one increases by 88% compared to the evacuation through the passenger compartment door, and the connection between carriages is prone to congestion; When evacuating in both directions, the flow rate of the doors in the upstream and downstream directions is the highest. As the number of evacuees increases, the flow rate of each door shows a significant imbalance.
