The Research Of The Planning On Metropolis Intercity Rail Transit

Urbanized advancement speeding up, caused the region to evolve to the giant urban cluster area, the metropolis belt, the metropolis continuous area or the cities community space unceasingly, the formation of this kind of metropolis circle, the metropolis continuous area either the cities community space request with the aid of the region or the interurban transportation network system, many metropolises take the large capacity fast rali transit system as the backbone, take the ground auxiliary conventional multi- types mass transit network as the supplement, multi-level, multiplex, the p-traffic way intercoordination comprehensive p-traffic system, and fully realized each kind of transportation way organically to transfer and link up, and take this metropolis synthesis p-traffic system as the municipal transportation development strategy. Therefore, there have the important practicatol of city transportation plan in our country, but metropolis circle rail transit plan research then just started, although has carried on the Yangtze River delta area rail transit plan, the Zhujiang Delta rail transit plan, also has yielded many results, but still has not formed the systemic theory and method.Based on the review of a great deal of domestic and overseas relevant literature, and integrating the theory with practice, the dissertation has carried out the study about the plan and design theory of metropolitan rail transit;The key of the research is on two aspect: passenger forecasting and layout plan theories.Firstly,based on the study of the similarities and differences between the metropolis rail transit plan and the city rail transit plan, proposed this article research thesis, first summarized the domestic and foreign research present situation, proposed key content and goal of this article;. Take the Yangtze River triangle area as the example, through the research of city border track transportation and the high-speed railroad, the ordinary railroad, the road and the city track transportation division of labor and the relations, has obtained the metropolis rail transit characteristic.Secondly, the model of the passengers forecast were studied. The corridor analytic method was proposed in the metropolis rail transit passenger flow forecast application, The traffic district for passengers forecast was raised, which is centered on the hub, circled with the radius of attrahent scope .The forecast model applying toestimating the volume of collecting and dispersing passenger generation and transfer passenger distribution are raised, the example proved that the models are reliability and practicable.Thirdly, the plan theories of metropolitan rail transit were studied. Based on the research of the analysis of the applications with the transport location theories and transport corridor theories in the process of metropolitan rail transit hub planning, the position methods of the rail transit hubs planning which the rail transit hub is located and then the rail transit network were put forward firstly. The key idea of the planning for the rail transit network and the hub was carried out firstly: Key position nodal analysis , Transportation corridor analysis, Rail transit network;This kind of "key position to network" procedure changed the tradition city background "the network to the key position" the plan method, causes the metropolis rail transit network and the large-scale passenger flow collection and distribution spot has very good linking up, is advantageous in the maximum attraction passenger flow.
