Study On Emergency Evacuation Of Arriving Passengers Inside Terminal

As the carrier of passenger throughput of civil aviation,airport terminal is a place of mass gathering.In case of earthquake,fire,explosion and other emergencies,it is necessary to evacuate a large number of people in the airport terminal in a short period of time.If the emergency evacuation path is not smooth or the emergency evacuation plan is not reasonable,congestion,stampede and even casualties and other safety accidents will occur.Especially when a relatively dense flight to Hong Kong,a large number of passengers at the airport in a short period of time,will be formed in a short period of time to the port of passenger,and the airport arrival layer channel is relatively narrow,winding structure,and reach the passenger travel most need after transformation floor,emergent cases keep clear of evacuation route and emergency evacuation plan of reasonable planning is particularly important.Evacuation of passengers to the port,its behavior is influenced by the outside of all kinds of environmental factors,is under the influence of crowd psychology,this article in to the port passenger emergency evacuation behavior characteristics and psychological characteristics of analysis,choose the social force model and carries on the improvement after the improvement of the social force model as the theory foundation of simulation modeling,After analyzing and elaborating the flow line of arriving passengers,Anylogic simulation software is used to simulate and study the emergency evacuation of arriving passengers in the terminal for example.This paper studies the idea of "finding bottlenecks--optimizing schemes--overcoming bottlenecks" in emergency evacuation of terminal arrivals under current arrival flow conditions:it puts forward suggestions on setting emergency evacuation facilities for terminal arrivals;Solve the congestion bottleneck of the evacuation exit of the mezzanine and the stairs on both sides of the arrival floor;So that passengers arriving at the mezzanine can evacuate nearby,effectively reducing the congestion phenomenon of mezzanine passage;To overcome the problem of blind evacuation and reverse evacuation of arriving passengers;The evacuation time is reduced by 48% compared with before optimization.Then,on the basis of optimization,a simulation study is conducted on the emergency evacuation of arriving passengers in terminal under the extrapolation of the level trend of arriving passenger flow.Through the analysis and calculation of the simulation results,it is concluded that when an emergency occurs in T2 Terminal of Zhongchuan International Airport,Conclusion: The maximum number of flights arriving at the port in rush hours is 9 when the evacuation time requirements are met and there is no serious evacuation bottleneck or congestion.
