Study On Urban Rail Transit Passenger Flow Analysis And System Design

Urban rail transport has gradually become the main means of urban passenger transport,because of its large capacity,fast transport speed,all-weather operation,safety and reliability,comfort and punctuality.It now occupies an important position in urban public transport.With the continuous improvement of the scale of the urban rail network,the increasing population of the city and the continuous growth of passenger travel demand,the transport pressure of urban rail transport is also increasing,so how to improve the operational efficiency and reasonable allocation of transport resources,so that passengers can have a comfortable,fast and efficient riding experience,so that the operator has a reasonable travel cost,operating efficiency,etc.,has become an urgent problem to be solved.This paper gives an overview of the passenger flow of urban rail transit,and relies on the2017-2021 metro passenger flow data of Xi’an Metro to conduct a detailed analysis in terms of the time distribution,spatial distribution,interchange passenger flow,passenger flow growth pattern and factors affecting passenger flow growth,and obtains the distribution pattern and change characteristics of passenger flow.The system is also designed to address the problems of urban rail transit passenger flow analysis,such as a wide range of content,large amount of data,complex logic and repetitive workload,etc.It has five functional modules: operation index management,line network passenger flow analysis,line network short-time passenger flow prediction and early warning,operation report management and network transportation plan preparation.It also discusses the multi-path algorithm for urban rail transit passenger flow;proposes a passenger flow matching algorithm based on WIFI data to address the problem of lack of passenger travel path dynamics in AFC system data;and investigates the LSTM-based short-time passenger flow prediction model,laying a solid foundation for the implementation of the urban rail passenger flow analysis system.The system adopts a layered,component-based development design and uses a B/S architecture with flexible,convenient and fast features,realising a city rail passenger flow analysis system with complete functions,easy operation and high visualisation,which is a good guide and help to improve the efficiency of city rail transport organisation,optimise the way of train operation organisation and organise traffic scientifically.
