Study On Location Method For Transfer Hub Of Routine Public Transit

Since Reform and Open in China, our urbanization process is more faster than ever in our country. With the speedy development of the city economy and the reinforcing contact among cities, the stable and floating population increases rapidly in the big city. In order to blancing the supply and requirement of transportation and making the urban transportation system serve the development of the city highly efficiently, founding the comprehensive transportation system in which the public conveyances are dominant and other traffic patterns cooperare is almost the only way to solve the problem of the transportation in metropolis. The routine public transit, which is the lowest social and best and best optimal integrated benefit as one passenger traffic mode, is the subject of the urban public transport. In the system of the routine public transit, the transfer hub of routine public transit is an important node, which affects the function of the routine public transit. Therefore, in order to improve the travel of the residents’efficiency, it must be have a reasonable construction for the transfer hub of routine public transit. Accordingly, there are several research contents in the following section:Firstly, the concept of the transfer hub of routine public transit is defined, the constructing significance is detailedly analyzed, and the transfer hub of routine public transit is detailedly classed.Secondly, the location work of the transfer hub of routine public transit is analyzed. The location factors which provide the basis for the variable of the model of the location are detailedly analyzed from the aspects of micro and macro. The principles of the location of the transfer hub of routine public transit which provide a theoretical basis for the location of the transfer hub of routine public transit are also analyzed. The transfer hub of routine public transit is divided into three groups to discuss and point the class hub of the middle and middle is the main object of the study. The existing location method are introduced in detail and the shortcomings of every method are pointed out.Thirdly, the alternative hubs for the determination of the transfer hub of routine public transit have being detailedly studied. Through the bus intelligent card to determinate the transfer point and the transfer passenger traffic. So this section includes the date processing of bus intelligent card. The throughout of the process of the travel of the residents is analyzed. The determine of the method of passengers who have bus intelligent card on the bus、off the bus and transfer points are detailedly introduced. The number of the transfer traffic is determined at the last. The method of identifing the alternatives of transfer hubs is provided in this section. In order to provide a method of date sources for the construction of the model.Finally, the location method for transfer hub of routine public is proposed which based on the optimization of multi-point. The related theories of multi-point optimization are detailedly analyzed. This related theories include the concept of the multi-point optimization^the indentification of the regional of the multi-point、the determination of the pre-optimal point、the setting of the optimization objective、the principle of the multi-point optimization. The locating model of transfer hub based on the optimization of multi-point is built with the lest travel cost, and the service quantity of transfer hub is limited. A case for Babao Street、Qingyang District、Chengdu is studied. And the inspection and conclusions of the location is in the last.
