摘要：针对近年来北京市缺乏具体统计数据反映公交服务范围不断增长的问题，突破以交通小区为分析单元的建模方式，以公交和地铁站点、站群为分析单元，建立了北京市公交模型。在建立了公交站群系统和公交网络系统的基础上，采用空间分析、数据融合等技术手段，对多源异构数据进行重组统合。以IC卡数据和调查数据为基础，建立了北京市公交出行OD矩阵，实现了公交网络客流模拟以及与市区交通模型进行数据交换与共享等多种功能，为北京市公交线网、站点的优化调整提供了技术支持。

Abstract: In light of the problems pertaining to a lack of actual survey data to reflect the increasingly growing areas of transit services in recent years in Beijing, this paper establishes the Beijing transit model by adopting transit(including bus and subway) stations or group of stations, instead of traffic zones, as basic analysis units. The model consists of a transit station system and a transit network system, and applies spatial analysis and data integration techniques to processing data obtained from different sources and with varying structures. The model is capable of generating Beijing transit OD matrices based on data derived from IC cards as well as surveys, and features multiple functionalities, such as simulating passenger flows on transit networks, and sharing/exchanging data with the Beijing transportation model, thus providing technical supports to optimize and adjust transit network and stations in Beijing.
