摘要
公交客流的ＯＤ分布是城市公共交通系统优化设计线路网和调配车辆所不可缺少的基础数据，本文把八十年代国外提出的使用路段断面车流量推算道路网中车辆出行ＯＤ分布的新方法移植到公交系统，根据各线路各车站调查的上下车人数推算公交客流的ＯＤ分布。这一方法已于９４年成功地应用于成都市，这在国内尚无先例，经成都市有关资料校核与通过人造网络的计算分析，表明精度是满意的。
The bus passenger OD matrices is the basis of optimizing the bus lines and the buses allocation in urban public transport system In this paper,based on the method of estimating the OD matrices of vehicles from observed flows,we develop a method of estimating the OD matrices of public transit passenger from observed passengers who get on and get off buses at bus stops This method has been successfully used in Chengdu in 1994 It was the first trying in our country After tested by datas of Chengdu and man-made networks we ean see the precision of the estimation meets the demands of design
