Design And Realization Of The Refined Service System For Passenger Transfer In Railway Hub

With the rapid development of high-speed railway network,more and more cities turn to transport hubs which connect more than one line and have a number of passenger transport stations.More passengers need to transfer in the hubs because of passenger flow increasing.When a railway hub contains a number of external traffic nodes including airports,bus stations and passenger transport stations connecting different directions and lines,it is very important for it to know how to guide passengers to complete their transfer process more efficiently,orderly and economically which can improve passengers' travel efficiency and ride satisfaction.At present,there is no satisfied software applying to railway hubs of searching and designing transfer path.Some path search software such as "Baidu Map" and "Gaode Map" can only search the path outside the station,which is limited to use for transfer process.Therefore,it is necessary to develop a system having function of path searching and integrated service to meet the passengers' demands of refined transfer.This paper studied the functional requirements and the core technology of the system,also finished its development.This paper mainly includes the following works:(1)Firstly analyzing the railway enterprises and stations' business requirements of organizing passenger boarding and transfer;Secondly analyzing the passengers' transfer demands through their transfer behavior in the railway hub.(2)Giving the definition of refined transfer service,analyzing the service content and mode which railway stations can provide for passengers.(3)Analyzing the demands of system,including its functional requirements,data requirements,interface requirements and performance requirements.(4)Designing the functional modules of the system,including basic data reading,hub's traffic information and hub's OD tree inquiring,station interior information inquiring and walking path searching,integrated transfer path searching,and completing the system database design.(5)Analyzing four technical difficulties of the system,including establishing and drawing the hub's integrated transfer network,drawing the hub's OD tree,searching the shortest walking path in the station and searching the integrated transfer path,and designing their algorithm and process.(6)Using the completed system to show the refined transfer service functions taking Beijing and Beijing South Railway Station as examples.
