Research On Operation Strategy Of Large Passenger Flow For Urban Rail Transit

With the acceleration of Chinese urbanization process,the urban population and the traffic demand increases rapidly.As an important part of urban public transport system,rail transit accounts for a large proportion.Ensuring the normal operation of urban rail transit system in the case of large passenger flow through scientific and reasonable operation organization strategy is an important issue of common concern of government officers,subway operators and researchers.The main research contents of this article are:(1)In view of the reasons for the formation of large passenger flow,a qualitative discussion and basic mathematical model reasoning were made.Study the passenger flow distribution characteristics of large passenger flow in the station and the passenger flow distribution characteristics of the line.Focus on the impact of large passenger flow on the operating organization.Analyze the impact of different levels of large passenger flows on the operation organization of urban rail transit.Obtain the critical conditions for large passenger flow.(2)Aiming at the carrying and transporting capacity of passenger flow at stations and lines,research the carrying capacity of lines,train transporting capacity,station carrying capacity for passenger flow and station capacity for large passenger flow.According to subway design specifications and operating technical specifications,the calculation results of passenger flow are obtained.(3)In view of the problem of how to organize the operation when a large passenger flow occurs,the method of ensuring the capacity and maintaining the normal order of the station through the organization of train and passenger transportation is studied.Combining the existing system and experience,the operation organization method for large passenger flow is proposed.
