摘要： 对公交到站时间预报技术进行了研究和探索。建立公交线网道路模型，根据GPS车载终端采集的公交车辆运行动态数据，推测路段交通状况及对应的路段行程时间，预测公交到站时间，并分析各种误差。实验数据表明，在2min误差内的预测时间准确率大于80%，基本可满足公交时间预报要求。

Abstract: This paper studies the prediction technology of bus arrival time. After building the model of public transport network, the road traffic situation and corresponding traveling time are speculated according to dynamic data collected by GPS vehicle terminals, and then the bus arrival time is predicted. Different kinds of errors are analyzed. The accuracy of this method is more than 80% within the range of two minutes error permission, which can generally meet the requirement of prediction for bus arrival time.
