Study On Adjustment And Optimization Of Conventional Bus Lines And Stations Along New Urban Rail Transit

With the healthy and stable development of China in social,scientific and economic fields in recent years,the urban land area is expanding and the degree of motorization is constantly improving,and the balance between supply and demand of urban transportation is broken,multiple challenges are imposed on urban transportation.A variety of initiatives,measures and solutions have been proposed by experts in the field of transport,especially the proposal to vigorously promote the priority development of public transport,which is of great significance for improving the quality of passenger transfer service,efficient use of resources,reducing passenger travel costs and improving the attractiveness and competitiveness of public transport.Therefore,from the perspective of optimizing the layout of rail transit and conventional bus routes as well as the location of bus stops,this paper comprehensively analyzes the relationship between the two.First,the two major transport systems should be analyzed in detail.Including their economy,transportation efficiency,resource consumption and service characteristics;To clarify the functional positioning of the two vehicles,so as to analyze the relationship between them;The influence range of newly built rail transit stations is analyzed,and the scope of passenger flow attraction is determined through aggregation effect,which lays a theoretical foundation for the initial optimization range of stations in the following chapters.Second,study the adjustment method of bus line network in the initial stage of rail transit operation.Firstly,the optimization target of bus network is determined,and the corresponding optimization strategies and methods are given.Secondly,the rail transit corridor bandwidth is analyzed to determine the relevant influencing factors of line optimization,and the routes are classified into six types by k-means clustering.Then,a route selection generation method was designed.A route generation model was established with the minimum travel time of conventional bus routes as the optimization objective,and the average station spacing,line length and line repetition coefficient as constraints.Finally,A* algorithm is used to solve the set results of the relevant lines to be optimized for Nanchang Line 1.Thirdly,the optimization of bus transfer station location.Firstly,the influencing factors,principles and locations of transfer stations are analyzed.Secondly,the local transfer topology network is constructed and the scale is determined.According to the constructed transfer topology network,the bus station location model is designed and the modular design algorithm in complex network community theory is used to solve the model.Finally,taking a bus station around a rail transit station of Nanchang City line 1 as an example,the algorithm and model designed in this paper are applied to obtain the solution results,and the scientificity,rationality and feasibility of the algorithm and model are verified.Based on advocating vigorously develop the concept of public transport,by rail transit and conventional public as the research object,the two main public transport of agents to the optimization of bus lines and bus stops your location make rail transportation and conventional public traffic transfer to maximize efficiency,passenger service quality improved quality,travel satisfaction improved,give full play to the two main public transport efficiency,Alleviate urban traffic problems.
