Study On Distributing Station In Urban Rail Transit Line

Rail transit as an effective way to solve the urban transportation question, its station distribution directly affects the exertion of rail transit benefit, brings profound influence on city spatial structure, land development along the rail transit line and so on. At present, there is no sufficient study in the field of the station distribution, station setting is mainly rely on the experience, inevitably, lead to many unreasonable phenomenon of station distribution, and also may suppress full exertion of rail transit function. Thus, systematic and synthetic study on the station distribution of rail transit has important theory value and practical significance.Basing On analyzing influence factors of station distribution, using domestic and foreign relevant successful experience and research technique for reference, implementing basic idea of "humanist, setting according to need, technology feasible, economy reasonable" all the time, this paper discusses stations distribution in urban rail transit line with qualitative and quantificational analysis, especially in vested rail transit line, and puts forward a method of forming station distribution plans restricted by station distances and numbers of stations, and also establishes a model used to determine the optimal station distance of rail transit lines which is taken least system cost as the objective function. Then, basing on forming stations distribution plans, this paper establishes a comprehensive evaluation indices system to elect the best station distribution plan. Finally, it combines programming of the second line of Xi'an rail transit lines to produce its reasonable station distribution plan, to exposit application of this method.
