Effect of subway train door opening strategies on passenger evacuation efficiency
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,con-structs 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 con-nection between carriages is prone to congestion;When evacuat-ing in both directions,the flow rate of the doors in the upstream and downstream directions is the highest.As the number of evacu-ees increases,the flow rate of each door shows a significant imbal-ance.
