The research on the construction of urban multi-modal public transport network and the method of generating effective route sets is beneficial to improve the overall efficiency of bus passenger flow assignment,and is of great significance for further strengthening the operation and management level of urban public transport and promoting the construction of urban public transport system.This paper makes an in-depth study on the analysis of urban public transport passenger flow from three aspects: the construction of double-layer network,the generation of effective route sets,and the assignment of public transport passenger flow based on routes.Firstly,this paper proposes a multi-modal public transport network construction method considering transfer characteristics and a multi-modal public transport network construction method considering line characteristics.Benefiting from the structural characteristics of the two networks,the basic path search method and the effective path set generation method are proposed in layers,which improves the search speed and search efficiency of effective paths.Secondly,based on the functional requirements of Tran Star,the functions of network construction,effective route set generation and bus passenger flow assignment are developed by using programming language.Finally,based on the Chongqing public transport database,completed the bus network construction experiment,the effective route generation experiment and the bus passenger flow assignment experiment,and analyzed the experimental results of each module in detail,and further expanded the technical method of urban bus passenger flow assignment. |
