Research On The Improvement Of Service Capacity Of Urban Rail Transit Station Under The Background Of Large-scale Sports Events

With the continuous improvement of China’s comprehensive national strength,the number and the frequency of large-scale sports events in China is gradually increasing.Urban rail transit has become an indispensable public transport mode in major sports events due to its huge advantages in capacity and reliability.As an important part and key node of urban rail transit network,the service capacity of urban rail transit station greatly affects the service level of the whole urban rail transit system.During the period of large-scale sports events,how to scientifically and reasonably improve the station service capacity,maximize the travel needs of athletes,spectators and other passengers,and ensure the smooth holding of large-scale sports events has become an important research topic of passenger flow organization in urban rail transit stations.The main work of this paper is as follows:(1)Analysis of passenger flow characteristics of urban rail transit station under the background of large-scale sports events.In view of the challenge of large-scale sports events to urban public transport system,this paper studies the passenger flow characteristics of related urban rail transit stations,and puts forward the influencing factors and mechanism of station service capacity under the background of large-scale sports events,which provides the basis for carrying out relevant capacity calculation and analysis.(2)The adaptability analysis method of urban rail transit station service capacity is proposed.This paper describes two methods of adaptability analysis of station service capability based on queuing network model and simulation software.In the aspect of analysis based on queuing network model,according to the characteristics of passenger flow line of urban rail transit station,the queuing network model and evaluation index system are constructed;In the aspect of analysis based on simulation software,the evaluation index system is established through environment modeling,pedestrian streamline modeling and parameter setting.The two complement and perfect each other to achieve a comprehensive analysis of the station service capacity.(3)The adaptability analysis of service capacity of Lianshanpo station of Chengdu Metro under the background of the 31 st Universiade is carried out and the optimization solution is put forward.The existing service capacity of Lianshanpo station is analyzed by using queuing theory model and anylogic simulation model and evaluation index respectively,and the bottleneck of capacity under different passenger flow characteristics during the station competition is found,and the general strategies and two optimization schemes for improving the service capacity of the station are proposed,Through the queuing theory model index and anylogic simulation model index,the service ability adaptability of the two optimization schemes are comprehensively evaluated and compared,and the out of station security check scheme is finally determined as the optimal scheme.
