A Study Of The Transportation Passageway Planning In Metropolis

According to the nature of the urbanization development, our country is being in the period of accelerating urbanization, many cities face the problems of large-scale space expansion, such as the rise of various development areas and industrial districts, new developed areas in cities and so on. At present there are many criticism about the cake-like spread pattern of urban space and many description on the multi-central clusters pattern, the call to change such pattern sounds high. But the study, on the traffic demand request and what scale of transportation facility between clusters, and how organizes the rail system, BRT system and road traffic system, is really few. The paper brings the synthetical traffic system between clusters into transportation passageway category in progress study. Research the transportation passageway type, method of traffic demand forecast and facilities planning thorough investigation and discussion. Here the study on the planning of the transportation passageway between clusters is made in this thesis, while the optimization of urban structure morphology is interlude among it.Firstly, unifies city structure on each stages, discusses relations among the urban transportation and the city structure morphology. Summarize the concepts and theories of transportation passageway briefly, and the concept of transportation passageway between clusters in metropolis scope. Analysis commonness and difference among transportation passageway, transportation aisle and urban develop axis. In this foundation, introduce the typology, focus on the research of passageway type under the multi-central clusters pattern. From the angles of represent form and function, divides the transportation passageway into four types——namely"the emission","the sutures","the development axis"and"the assistance".Next, the traditional thought of transportation demand forecast simply reviews, the relation between the urban structure morphology and the transportation demand are analyzed. The concept of transportation demand concept between clusters is given, thoroughly a series of influence factors on it are analyzed. In this foundation, composition of the transportation demand between clusters analyzed, the simple forecast thought and method is given. Utilize the conclusion of the research in fore parts, the transportation among clusters in Hang Zhou is forecasted.Finally, the influence factors on the traffic pattern between clusters are analyzed thoroughly, such as the physical geography condition, cluster function characteristic, scale, and so on. According to the passageway characteristic and request, the capability of the transportation system is classified and analyzed. The method on account the scale of the different transportation system in passageway is studied. For the complexity of road system, the road system scale, structure and computational method in passageway are studied particularly. The road structure form and layout principle are summarized. On the foundation above two part, the passageway facility planning between the Hang Zhou chief-city and Jiang Nan sub-city is proposed.
