Study On Distributing Optimization Of Urban Rail Transit Station

With the development of our social economy and the advancement of urbanization,people pay more and more attention to traffic travel, especially in long-distance traffic travel.The advantage of urban rail transit become increasingly apparent because of its features suchas fast, large capacity, punctuality, safety, energy saving, comfort. In recent years, many citiescontinue to expand urban rail transit construction, in the meantime, most of distribution ofurban rail transit station are relying on the experience of policy-makers, systematic theoreticalstudy support system is not enough, but the distribution of urban rail transit is not related tothe travelers’ convenient travel, but directly affect the operational efficiency of urban rail lines.This paper focuses on the distribution of urban rail transit station issues as research work:First introduced the role of urban rail transport, classification, characteristics andcomposition, and analyzed a number of successful domestic and international rail transportplanning scenarios, combining theoretical and practical, comprehensive and objectivesummary of the impact of rail transit site layout factors, from urban rail transport on thepassenger’s attracted coverage for passenger travel, the interface between the transportation,construction difficulty and cost, improve operational efficiency and other aspects of theanalysis, station spacing for subsequent optimization model provides the basis.Second, in the analysis of rail traffic on the basis of various factors, according to theoptimal station spacing layout methods, combined with the amount of site coverage analysis,at least based on passenger travel time optimal station spacing models and algorithms, and themodel using VB programming the solution, the calculation results are analyzed.Again in accordance with the established urban rail transit station spacing of the optimalmodel, combining urban rail transit line site layout factors on the site layout alternatives forevaluation and analysis. Evaluation system established criteria level, through the graycorrelation method to each program in each index dimensionless weight after giving anassignment, in accordance with the rights of small material to sort through comprehensiveevaluation and analysis methods to get the optimal solution.Finally, the proposed model algorithm and evaluation system, the Beijing subwaypassenger flow along the line fifteenth carried out analysis and forecasting, calculate theoptimal distance between stations and gives the site layout options, through gray correlationanalysis method to evaluate each analysis of alternatives were evaluated through thecombination of qualitative and quantitative methods calculated the optimal solution, and thefuture of urban development plans in accordance with Beijing and Beijing Subway summarizerelevant experience overall plan put forward reasonable proposals.
