【摘要】 分析晚间运营时段影响乘客换乘末班车路径可达性的路网结构、换乘站结构和列车运行方式等因素,以及城市轨道交通乘客信息服务系统终端的显示特性,明确推算换乘路径可达性需要考虑的约束条件和客流诱导信息的发布形式。构建换乘路径可达性模型,设计选择算子、交换算子和变异算子,应用遗传算法对模型进行求解。基于此,分别面向乘客和信息发布的系统业务人员,设计基于末班车时刻的城市轨道交通末班车客流诱导系统,提供面向乘客的指定OD的换乘路径可达性查询和当前时刻下进站路网可达车站信息查询的功能,以及面向管理人员的基础数据管理、发布信息核查及信息发布管理等功能。以北京2012年城市轨道交通路网和末班车时刻为例,验证了该系统对指定OD换乘路径可达性的查询功能。更多还原

【Abstract】 The accessibility impacts of transfer route of urban rail transit network,such as network structure,transfer station structure and train schedule are surveyed,and the characteristics of display terminals of passenger information system(PIS)of urban rail transit network are investigated.The constraints of model about analyzing the accessibility of transferring route in the evening are determined.The styles of guidance information are described according to the characteristics of PIS.The reckoning model of the accessibility of transfer route is constructed in accordance with the constraints,and solution to the model is found based on Genetic Algorithms(GAs),selection operator,crossover operator and mutation operator are designed.Then,the function structure of passenger guidance system is drawn out.The passenger-oriented functions of querying and browsing guidance information are planned.The above functions make sure that passengers will query the accessibility of designated transferring routes at appointed time,and look over which accessibility between a certain station and other stations at present.The staff-oriented functions are designed,which include managing the infrastructure of network and station,checking upcoming guidance information and managing the event of information distribution.Finally,based on the structure and train operation schedule of urban rail transit in 2012,an instance is used to verify the querying functions of accessibility of between two appointed stations at appointed time.更多还原
