Adjustment Of Regular Public Transportation Network Based On Urban Rail Transit

With the vigorous development and rapid construction of urban rail transit, it plays a more and more important role in the public transport system in China. The operation of the rail transit will definitely compete with the existing conventional public transit. However, neither of them can meet the different demand of different kinds of people alone, for both of them have their individual limitations. Therefore, it seems that only by combining urban rail transit with conventional public transit, adjust the conventional bus station and network allocation appropriately, can the urban rail transit give full play to its effect and overall efficiency, so as to get a "win-win" situation for both the urban rail transit and the public transport system.This paper first makes a summary on the theory and practice study of the conventional public transit line and network corporation based on rail transit operation both at home and abroad. After that this paper carries out the passenger flow analysis and function orientation based on the technical and economical characteristics of the above two major public transport forms. Conventional public transit network adjustment problem with rail transit as the core has been studied from three aspects, which are bus station, bus line and public transit line network. The conventional public transport adjust methods have also been analyzed.In the conventional public transit station coordination and optimization process, using maximize the station transfer passenger person kilometers as the objective function, this paper built an optimal select model which can connect the origin station and the terminal station, and the optimal station spacing solving model has been built on the principle of minimum the total travel time of the passengers. This paper also discussed the conventional public transit line adjustment method to achieve the line feeder task from two aspects which are conventional existing public transport adjustment and newly increasing public transit feeder lines. Using maximize the feeder efficiency of the passenger person kilometers as the planning objectives, the feeder efficiency model has been built.Finally, this paper makes an analysis of the current operational situation of conventional public transit along the Chengdu Subway No.1 Line; adjust the surrounding bus station and the bus line alignment.
