Emergency Evacuation Simulation And Optimization Of Xi’an Road Station In Dalian Metro

Due to its characteristics of high efficiency,punctuality,safety,and comfort,the subway has become the preferred mode of travel for more and more people.Therefore,the passenger flow of the subway has gradually increased,and in particular,the passenger flow of the transfer stick has grown rapidly.The Xi’an Road station(the transfer station of Line 1 and Line 2)of the Dalian Metro studied in this paper not only bears a large amount of passenger flow attracted by Xi’an Road Business Circle,but also undertakes the passenger flow of Metro Line 1 and Line 2.According to the survey,queuing will occur within the station during peak hours,leading to pedestrian crowding.When an emergency occurs,the emergency evacuation will take lonager.Therefore,it is of great significance to study the emergency evacuation of Xi’an Road interchange station,to reduce the bottleneck problem of evacuation,to shorten the evacuation time,and to ensure that passengers can evacuate to a safe area within safe time.This paper aims at the modeling and simulation research of Xi’an Road Station’s service facilities and passenger flow in and out of the station The article first elaborated the relevant theories on pedestrians,evacuation and simulation.It introduced the layout of subway stations,the selection of platforms,and the classification of service facilities in detal.At the same time,the characteristics of passenger flow at Xi’an Road Station,normal passenger flow,and The princples of passenger streamlines and passenger flow organization during emergency evacuation were systematically analyzed.Then based on related theories,the s:imulation parameters of the emergency evacuation model were determined based on the Anylogic simulation platform,and the simulation logic and physical models were established according to the actual conditions of Xi’an Road subway station The emergency fire emergency evacuation of the station was simulated through simulation experiments.According to the simulation results,the bottleneck problem of Xi’an Road subway station evacuation process was obtained.Finally,an optimization scheme is proposed for the bottleneck problem Through investigation and analysis of the impact of the optimization scheme on the station pedestrians,the model parameters are modified and the optimization experiments are conducted to solve the bottleneck problem of the station The conclusion is drawn through comparative analysis.Through the analysis of the simulation results,the areas that are more congested in the evacuation process are:the security inspection machine near the A port in the station hall,the stairway leading to the No.1 line near the B port,and the access to the No.2 line near the A port.Stairs and landings lead to landings on the landing floor.The pedestrian evacuation is guided by the addition of clear indication signs at the station hall and platform floors,and the vacant positions on both sides of the gate and the security inspection machine are set as openable dividers to optimize the model Finally,the evacuation time was controlled within 6 minutes,the bottleneck problem of station evacuation was improved,the pedestrian gathering phenomenon was resolved,and the emergency traffic capacity of the gate and security department was obviously enhanced,which provided a reference for emergency emergency evacuation design of the station.
