Method Study On Transfer Streamline Design Of Railway Passenger Transport Hub

The railway passenger transport hub is an important node to realize the transfer between different modes of transportation.The rational design of the transfer streamline is the core requirement.In the practice of transfer streamline design,the architects design streamline based on the layout of the building space.However,the layout method of different modes of transportation areas is immobilized,with large scale areas and long transfer distance.Also,the quantitative support is not enough to figure out the complex passenger flow demand.While,traffic designers focus on the back-end streamline organization with small optimization.With urban function integrated in railway passenger transport hubs,the development trend of intensive,vertical,complex transport hub is inevitable.The layout of different transport mode areas would also be vertical,scattered and flexible.Therefore,more and more attention is paid to the streamline’s chain function to contact passenger flow demand,streamline network construction,facility configuration and building space design.Research on a method to integrate above is a beneficial attempt in the refined and user-friendly design of railway passenger transportation hub.The development trend,classification and composition of railway passenger transportation hub are analysed in detail.Based on the redefinition and analysis of transfer streamline,a three-stage transfer streamline design method is proposed,including transfer process analysis,transfer streamline network construction,transfer facility and building space configuration.In the stage of transfer process analysis,the subjects,content,connections,demand,and required equipments of transfer activities are analyzed in detail.The stage of transfer streamline network construction is divided into two parts: initial streamline network construction and streamline network optimization.The first part takes the transfer efficiency as the main consideration.Firstly,the thesis analyzes the influencing factors of transfer border areas’ location choices for each mode of transportation and makes all the accepted choice optional.According to the priority order of each choice,the transfer border areas’ locations are decided.Secondly,based on the analysis of pedestrian path selection influencing factors,the basic transfer streamline network is generated and optimized.Thirdly,transfer demand is distributed on the basic network with the improved algorithm of shortest path traffic assignment.Finally,the assignment schemes of initial transfer streamline network are compared and optimized according to different choices of transfer border areas’ locations.This thesis constructs a program to realize the automatic generation and comparison of the initial transfer streamline network.In the second part,space syntax theory is introduced.Convex space analysis,sight analysis,axis and line segment analysis are conducted to the basic transfer network.Various of variable parameters are calculated.The overall optimization factors of streamline network are analyzed.Also,the optimization strategies of streamline network are proposed.In the stage of transfer facility configuration and building space design,the thesis firstly defines the concept of transfer stream functional nodes and classifies them into three categories.Secondly,the layout of functional nodes are considered as chain of transfer facility configuration,transfer streamline space design and transfer orientation guiding system layout,and conducted corresponding to transfer flow analysis and transfer streamline network structure.Based on the traffic flow of the functional nodes,the scales of the facilities and the building space are calculated.Finally,the composition and grading of the orientation guiding system are analyzed.The thesis proposed the layout method of the orientation guiding system by the functional nodes’ type.The three-stage transfer streamline network design method is carried out on Wuxi North Square Railway Passenger Transport Hub.The transfer process analysis,the transfer streamline network construction,the facility equipment configuration and the orientation guiding system layout are conducted to verify the validity and feasibility of the method.
