The Research On Passenger Evacuating For Emergencies In Terminal Departure Hall

In recent years,emergencies take place frequently in large-scale public places for both domestic and foreign areas.These phenomena are even worse for high density crowed regions.Airport,as one of the important transit facilities for aviation transportation,is also a passenger-gathering place,in which the increasing risks of emergencies come to be even worse in terminals.Passenger's evacuation in emergency is considered as a complicated system,which not only takes passenger's normal behavior characteristics into account but also focuses on their complex behaviors in emergencies.According to the research about passenger's behavioral activities,it can be found that the traditional research methods such as animal experiments,crowd evacuation drills are difficult to operate and cost too much.But,the Computer Simulation Technology can help to establish simulated model of passenger's emergent evacuation,and this model is able to present the real behavior characteristics of passengers.This paper conducts deep studies from the following aspects: the characteristics of passengers in emergencies,the factors influencing passenger's behavior in emergent events,and the basic theory of passenger evacuation.Based on the Social Force Model,this paper chooses the Mianyang Nanjiao Airport as an object,and conducts a simulation of the passengers evacuation in emergency in Terminal Departure Hall on the Anylogic simulation platform.In order to obtain the required parameters of the simulation,the author conduct a field survey on the Mianyang Nanjiao Airport.The main contents of the survey include the following perspectives: the CAD map of the Terminal Departure Hall in Mianyang Nanjiao Airport,the number of service facilities of the Departure Hall,the number of working staff and the design routes of emergency evacuation of the Departure Hall.Based on this information,the core simulation parameters are established,which mainly include the pedestrian size,the rule of passenger's arrival,the initial speed of evacuation,the number of departure passengers at peak hour,the standard of evacuation time,and so on.According to this established simulation model,the different status of passenger'semergency evacuation under different passenger flows were analyzed.By referring to the "Subway Design Code",the Emergency evacuation time in Terminal Departure Hall is set as 6minutes,to simulate the emergency evacuation in Mianyang Nanjiao Airport Terminal Departure Hall under different busy degree.The results show that emergency evacuation can be finished in 6 minutes under the condition of passenger's rush peak.Meanwhile,the author also find that there is an obvious congestion in the gate of the terminal,both left and right evacuating stairs,and security areas.Based on these,two solutions are proposed: increasing the manual dredging and changing the queue of security check.The simulation results show that the two schemes can effectively shorten the time in emergency evacuation.
