Transfer Efficiency Analysis And Passenger Flow Organization Of Passenger Transportation Hubs

Integrated passenger transport hubs in large cities play an important role in the development of integrated transportation system. Their layouts and operation directly affect the efficiency and level of service of overall transportation networks. The design methods and operation strategies of transport hubs attract much attention from researchers and operators. With the rapid development of social economics in China, passengers require the satisfaction of traffic demand and high level of transportation service. Research on the reasonable planning and organization methods on passenger hubs are much practical to improve the efficiency of operation and deep academic research on transportation organization and technology.This thesis aims to analysis the efficiency of transfer in transport hubs and to propose the methods of operational organization. The focuses of this thesis include how to classify transportation hubs and define and analyze the efficiency of transfer and optimization method of passenger flow organization.The content of the thesis are as below.(1) For the planning and operation of passenger hubs, the conceptual extension and operation issues of passenger hubs are presented based on the analysis on operational mechanism of passenger transport hubs. The categorizing and classification methods of passenger hubs are developed based on the scale and number of infrastructures and equipments according to the current national standards and industrial criterions. The proposed methods are carried out to analyze the operational efficiency of real-world passenger hubs, including Beijing South Railway Station and Shanghai Hongqiao Hub.(2) A model to calculate the transfer efficiency, in terms of passengers'passing time and density, of transport hubs is presented, through analyzing the passenger transfer process due to movement features and operational characteristics of passenger transport hubs. The model takes the passenger walking at underground channels and stairs as a waiting process in a queuing system with multiple level services. The model could be used to optimize the operation process and design of transfer routes, as well as analyzing the factors that may impact transfer efficiency in transport hubs.(3) A service network of transfer is proposed regarding different kinds of facilities and equipments in transfer hubs as nodes, to optimize the layout of facilities and equipments in passenger transfer hubs considering the trade-off between demand and supply sides. The total cost of transfer facilities includes not only the acquisition costs and operation costs of facilities, but also the change of passengers' transfer time due to the set up of the facilities. The allocation optimization model for transfer facilities in passenger hubs is developed to minimize the total cost of transfer facilities. A case study and simulation analysis through Anylogic is conducted to verify the optimization results from the proposed model.(4) The optimization model is proposed with the object of the entire streamline of passenger transfer process in transport hubs, which include the overall routes from arriving or alighting at transport hubs to leaving or boarding vehicles. The passengers are usually divided into three types:arriving and leaving, transferring between the same and different transport modes. The assignment of passenger flow is analyzed taking into account the characteristics of passenger flow, structure of network and its topology as well as travel impacts. Due to this requirement, transport hubs are described as nodes and arcs. The former presents the facilities in transport hubs, like corridors and security facilities, whose weights are able to be given by the cost of passengers passing them. The latter is defined as the connections among all types of facilities. A topology of network with nodes and arcs is constructed to optimize the filament line of passengers to reduce the total transfer cost of all passengers.Passenger transport hubs are a complicated social and economical system among which passenger behavior, construction schemes of facilities and categorical attributes of passengers relating to the functions of transport hubs lead to the difficulty of optimizing passenger routes. More issues on transport hubs are worth discussing further in the future work.
