The Method Of Traffic Design For Urban Public Transportation Hub

Along with the speedy development of the city economy and the improvement of the urbanization level in our country, urban traffic congestion, traffic accidents and traffic pollution caused by road traffic emissions have drawn the society's great attention. In order to balance the requirement and supply of transportation and make the urban transportation system serve the development of the city highly efficiently, the comprehensive transportation system established is almost the only way to solve the problem of the transportation, in which the public transportation is dominant and other traffic patterns assist it.This paper, aiming at the deficiency of the comprehensive transportation system in the big city in our country and referring to the successful experience in the developed country, studies the core of the urban public transportation system——the method of traffic design for urban public transportation hub. Firstly, the author reasonablely defined the urban public transportion hub, and analyze the methods to sorted and classed the urban public transportation hub. And then, the paper discussed the attract range and the calculation of reasonable attract range for the different tapes of hubs, and summarized the design flow and methods of traffic design for the urban public transportion hub.Secondly, the paper analyzed the system structure of urban public transportation hub in the software and hardware, studied the fuctional requirements and traffic organization design in the internal and external for the different types of hubs. Base on this, the author discussed the cohesion between the different traffic modes. Thirdly, the paper understood the essential demand, design Principles and design goal of traffic design for the urban public transportation hub. Base on this, the author studied the forms of layout for the different types of hubs, as well as the advantages, disadvantages and applicability of the various forms, and put forward the demand the method of detailed design for the different facilities. Finally, the author studied how to value the traffic design program of the urban public transportation hub, put forward some commonly quantitative and qualitative evaluation indexes, and introduced the evaluation steps of the analytical hierarchy process.
