轨道交通接驳的社区公交线路优化研究

ABSTRACTIn recent years,China's urban rail transit has stepped into a mature development stagefrom the initial stage,and various forms and volumes of rail transit construction have sprungup in various cities.However,according to the early urban rail transit construction andoperation experience of some cities that took the lead in planning and constructing rail transit,the lack of community bus lines connected by rail transit greatly limited the attraction ofurban rail transit passenger flow,and greatly reduced the benefits of rail transit construction.The emergence of community bus provides a valuable solution to effectively play thebackbone role of urban rail transit in urban transportation,and increase the passengerattraction and accessibility of rail transit.Firstly,this paper analyzes and summarizes the development research of community busat home and abroad and the connection forms of rail transit,and discusses the passenger flowattraction scope of urban rail transit stations,so as to classify the stations from the aspects ofland use characteristics around the stations,so as to determine the passenger flow attractionscope of each station,From this,the reasonable optimization range of connecting communitybus lines is obtained.Finally,taking the exhibition center station and the surrounding area ofscience and Technology Park Station of Liuzhou Rail Transit Line 1 as the research object,this paper analyzes the current situation of the public transportation network,optimizes thecommunity public transportation line of the traffic community that does not meet the demandof rail transit connection,and establishes the optimization model of the community publictransportation line of rail transit connection,and uses the model to solve the problem.Key Words:Community Bus;Route Optimization;Rail Transit Connection GeneticAlgorithm1
