The Study On The Urban Rail Transit Feeder Bus Routes Optimization

At the present time, in order to prevent the increasing private transport from entering city centre, the efficient alternative means of travel should be proposed. More important roles are placed on urban public transportation due to the population growth and expansion of urban areas. However, neither the conventional bus nor the rail transit service is sufficient to serve the various of demands due to their respective limitations. The widely accepted solution now is an integrated public transit system combining rail and bus services to meet the demand either jointly or individually, and complement each other to achieve better operating performance and stimulate demand. Therefore, the study on the urban rail transit feeder bus routes optimization is made.In this thesis,four main aspects are studied that is mechanisms of urban rail transit-feeder bus system; service characteristic of urban rail transit feeder bus system; models and algorithms of urban rail transit feeder bus network optimization; urban rail transit feeder bus routes optimization and adjustment. In the study of mechanisms of urban rail transit-feeder bus system, the advantages and disadvantages of bus and rail transit are analyzed, and the conformity of bus and rail transit is put forward. In the study of service characteristic of urban rail transit feeder bus system, the trip cost of passengers are analyzed, the model of marginal trip distance is constructed, and the layout region of feeder bus routes is analyzed. In the models and algorithms of urban rail transit feeder bus network optimization, the model of the urban rail transit feeder bus network optimization is constructed, base on the target of the minimum time cost and operation cost, the GA is built for the model. In the research of urban rail transit feeder bus routes optimization and adjustment, the adjust measurements of bus routes are analyzed, and the layout of feeder bus routes is studied. The planning of Guangzhou-panyu urban rail transit feeder bus routes is taken as actual example for study in this thesis.The study on the urban rail transit feeder bus routes optimization has the extremely vital significance to the city development. Because of this, the urban rail transit feeder bus routes optimization is studied and actual researchful example is given in this thesis. It can offer reference for the scientific decision of the optimization of urban rail transit feeder bus routes in certain degree.
