Research On Construction And Simulation Of Social Force Model For Emergency Evacuation Of X Metro Station

Urbanization’s progress has caused the permanent resident population in cities to swell,while urban areas are being modernized and infrastructure construction is being done in a systematic fashion.As th e backbone of urban transportation,subway stands out due to its advantages such as large transportation capacity and small impact from ground buildings.Therefore,major cities gradually build subway lines an d continuously improve their subway network.However,as the coverage area of the subway network expands,the daily passenger flow at various subway stations is also refreshin g historical records.Maximizing the security of passengers and property in the event of an emergency is a crucial responsibility in urban administration.This paper proposes a social force model,incorporating passenger behavior,to tackle the present issues in the X subway station’s emergency evacuation process,based on the research background.Firstly,by using literature research and field research,the operation and architectural structure of X Metro Station are described,and on this basis,the facilities,passenger flow,and path of X Metro Station are analyzed.In this article,the facilities of X Metro Station are divided into two types:service type and guidance type,which are respectively responsible for providing corresponding services for passengers and guiding them towards their destinations;The passenger flow situation is divided into regular large passenger flow and sudden large passenger flow for cause analysis;The path is divided into one-way paths and cross paths based on whether there are passenger flows with different directions of movement,and the one-way path area and cross path area of the X subway station are labeled.Secondly,by analyzing passenger behavior,this article constructs three types of passenger specific behaviors,namely panic behavior,guidance behavior,and helping behavior.At the same tim e,based on the social force model,passenger behavior is added to form a social force model that integrates passenger behavior.This model not only has the mechanical and kinematic foundation of the social force model,but also implements three specific passenger behaviors through agents.During the evacuation process,it can simulate the reduced evacuation speed and improper exit selection caused by passenger panic;Passengers are guided by guidance personnel and guidance signs to adjust their moving targets;After a passenger falls,normal passengers in the vicinity provide assistance.Finally,the evacuation simulation environment of X Metro Station is restored proportionally using Anylogic software.A comparison of evacuation time and efficiency between the original social force model and the one that integrates passenger behavior reveals alterations,prompting a comparative analysis to be conducted.Finally,based on the analysis of simulation results,an optimization strategy for emergency evacuation of X subway station is proposed.An examination of the functioning of X Metro Station was conducted in this article,with a social force evacuation model for X Metro Station that amalgamates passenger behavior being created.Additionally,evacuation simulation experiment analysis was utilized to devise emergency evacuation optimization strategies for X Metro Station,which is of great importance in enhancing the efficacy and security of passenger evacuation at X Metro Station.
