Study On Quantitative Methods Of Facility Scale In Comprehensive Transportataion Hub

Comprehensive transportataion hub is the key link of modern comprehensive transporation system construction. Its planning, design, and construction are reasonable directly impact of the cooperation between and performance of modes, of the passenger transport integration with the public transit being developed first as its main parts. Of the convenience of travelers and the level of people-oriented service. The article research from the object of comprehensive transportation facilities, analysis focus on two main factors which influence the scale of facility, that is the promoting of passenger demand and the restraining effect of the road capacity. Then, determine the production scale index of the comprehensive transportation hub. Finaliy, according to the relevant norms and standards, research the different methods of quantifing the scale of facilities, and Qualitative analysis based on the other factors, and then adjust according to the actual. The article provide the main basis for the city planning about reserving the land for the comprehensive transportation hub, and promote the integrated transport integration.First, the article has analyzed the theory of the comprehensive transportataion hub. It propose the definition and classification of the comprehensive transportataion hub, and it study its function, then, illustrate the relationship between the comprehensive transportation hub and the integrated transport network, and summarize the domestic status of the comprehensive transportataion hub. Second, the article forecast the traffic demand of the comprehensive transportataion hub. It analysis the various modes, the transportation characteristics of the various modes, and the composition of passengers. And, then it put forward the idea of passenger flow forecasting, explore the forecasting methods of the passenger flow volume and the contribution rate of various of transportation. Next, according to the result of forecast, subjected to the transport network capacity, analysis the transport network capacity of the mian roads. So, determine the production scale index of the comprehensive transportation hub. And, according to the production scale index and the relevant norms and standards, research the different methods of quantifing the scale of facilities, and qualitative analysis based on the other factors, and then adjust according to the actual. So, achieve the maximum function of the comprehensive transportation hub. Finally, by example, verify the above qualitative methods of various types of facilities to achieve the purpose of theory and practice.
