Simulation Of Emergency Evacuation In Departure Hall Of Terminal Considering Panic Factor

With the rapid development of social economy and the continuous improvement of transportation facilities and infrastructure,people’s travel modes are becoming more and more abundant,and the passenger flow of China’s civil aviation industry has repeatedly reached new highs.However,the increase of passenger flow will bring great challenges to the airport emergency system,especially the emergency evacuation under sudden events.So far,emergency evacuation brought by sudden events in airport terminals at home and abroad are common.How to ensure the safety of evacuees,control crowd panic,reduce irrational behavior and achieve rapid and effective evacuation are important issues which are worth to study.Therefore,Based on the existing research results at home and abroad,this thesis studies and constructs an emergency evacuation simulation model considering panic factors,and takes the domestic departure hall of the terminal T2 of X airport as an example to conduct research.The main contents include:(1)Build an emergency evacuation simulation model considering panic factors.Based on the emotional infection theory of heat diffusion mechanism,this thesis introduces the psychological stimulation of emergencies to evacuated crowd,quantifies the panic of pedestrians,and establishes the emotional infection mechanism among pedestrians.Based on the existing theories,modified the social force model in accordance with index of panic emotion,combined the panic emotion and the evacuation exit decision of the pedestrians,simulated the irrational actions of the pedestrians.(2)Build the emergency evacuation model of the departure hall of the case airport.Investigate the passenger throughput of the case airport,analyze the structural layout of the departure hall of the terminal,and build the emergency evacuation model of the departure hall of the terminal by using AnyLogic software based on the survey data.It includes the construction of the physical environment of the departure hall,the construction of process logic of pedestrians and the construction of evacuation information transmission model under emergencies.(3)The constructed emergency evacuation simulation model of the terminal departure hall is used to simulate and analyze the pedestrian evacuation under different evacuation conditions which include whether to consider panic emotion,different emergency locations,different alarm times,different evacuation exit failures,and whether to consider staff evacuation guidance.The results show that the psychological impact of emergencies on pedestrians cannot be ignored,and the produced panic emotion will spread with the movement of the crowd,resulting in the decline of the overall evacuation efficiency;Ensure that the evacuation passage of the people affected by the incident is unblocked can significantly reduce the overall number of panic people in the evacuation;In some cases,delaying the sending time of evacuation alarm can effectively reduce the spread range of panic emotion and improve the evacuation efficiency of people;For congested areas under different scenarios,adding guidance personnel can effectively calm the panic of evacuated people and improve the evacuation effect,and provide corresponding evacuation management suggestions for managers according to the results above.To sum up,this thesis mainly considers the impact of emergencies on pedestrian panic emotion and the impact of panic emotion infection among pedestrians on evacuation.The constructed model can simulate a more real evacuation scene,which can not only provide some reference for the future research in the field of panic crowd evacuation,but also provide effective help for the strategies formulation of airport emergency management.
