The invention discloses a passenger transfer station identification and trip chain reconstruction method based on IC card data, and belongs to the technical field of urban public traffic operation. The method comprises the following steps of: constructing a multi-mode public transport network topological graph by using public transport lines and station data by virtue of graph theory knowledge; secondly, acquiring starting and ending points of each trip of the passengers on the basis of IC data of the passengers, and acquiring transfer stations of the passengers in a subway system and transfer information between ground buses and between ground buses and subways in combination with bus network topology; on the basis, according to the condition of transfer between ground buses and between ground buses and between ground buses and subways, the time interval and the station distance interval of two-time continuous card swiping of a getting-off station and a next getting-on station of the passenger are calculated, whether the two-time card swiping is a transfer trip or not is judged by setting a space-time threshold value, and finally the whole trip process of the passenger is obtained. And reconstructing passenger public transport trip chain information.
本发明公开了一种基于IC卡数据的乘客换乘站点识别及出行链重构方法,属于城市公共交通运行技术领域。首先借助图论知识,利用公共交通线路与站点数据构建多模式公共交通网络拓扑图;其次,基于乘客IC数据获取乘客每次出行的起终点,并结合公交网络拓扑获取乘客在地铁系统内部的换乘站点,以及地面公交与地面公交、地面公交与地铁的换乘信息;在此基础上,针对地面公交与地面公交、地面公交与地铁换乘的情况,通过计算乘客下车站点和下一次上车站点两次连续刷卡的时间间隔和站点距离间隔,通过设定时空阈值判断两次刷卡是否是换乘出行,最终得到乘客的出行全过程,重构乘客公共交通出行链信息。
