本发明公开了一种高频gps点的公交车辆实时路口预测方法和系统,克服了现有技术在实际应用中难以实现的问题,包括步骤一、接收高频GPS点的公交车辆实时GPS数据、基础线路轨迹和路口经纬度信息;步骤二、对接入高频GPS点的公交车辆实时GPS数据进行清洗;步骤三、基础线路轨迹的轨迹点所属下一路口;步骤四、高频GPS点的公交车辆实时GPS与带路口的基础线路轨迹匹配;步骤五,判断线路上下行方向及实时轨迹位置。本发明通过参考基础线路轨迹,在路口预测过程中,尤其能够识别弯曲道路的即将到达路口,预测准确度高。

    The invention discloses a bus real-time intersection prediction method and system of a high-frequency gps point, which overcome the problem that the prior art is difficult to realize in practical application. The method comprises the steps of 1 receiving bus real-time GPS data, a basic route track and intersection latitude and longitude information of the high-frequency GPS point; 2 cleaning real-time GPS data of the bus accessed to the high-frequency GPS point; 3 determining the next intersection to which the track point of the basic line track belongs; 4 matching the real-time GPS of the bus at the high-frequency GPS point and the basic line track with the intersection; and 5 judging the uplink and downlink directions and the real-time track position of the line. According to the invention, by referring to the basic line track, in the intersection prediction process, the to-be-arrived intersection of a curved road can be identified especially, and the prediction accuracy is high.
