A Study On Movement Model Of Liner Passenger Evacuation In Emergency

With people's life becoming better and better, the tourism has been becoming more and more popular, which develops the passengers transportation by sea. Since the development of water shipping, serious fire disaster on passenger liner occurred frequently, which cause serious casualties and wealth damage. Characteristics of the passenger liner, such as the comparative closeness, limitation of escaping routes, and long time consumption for escape, hinder the passenger evacuation in emergency seriously.Firstly, this paper analyses factors affecting the safe evacuation, including objective factors and subjective factors. In the objective factors part, the major factors affecting the evacuating time are analyzed; while in the subjective factors part, the inadaptability factors, such as theories about panic, about emergency degree, and about decision making, are introduced, in which people's response in emergency is specially analyzed. Secondly, the simulation model of mass movement is briefly introduced, through which, the process of mass movement is displayed. The model of safe evacuation cumulative time is made through major factors and parameters analysis in safe evacuation model. According to characteristics of onboard people evacuation in fire, choking phenomenon during the process of safe evacuation on passenger liner is studied, and the evacuation on passenger liner is analyzed. By employing mathematical model, mechanism of choking in evacuation is analyzed, and the related factors and controlling methods are studied, which leads to suggestions for safe evacuation in passenger liner.
