The invention discloses an algorithm for calculating estimated arrival time of a vehicle based on a bus GPS, which comprises the following steps of linking a plurality of areas close to stations on the basis of GPS-based inter-station travel time survey data of the bus, predicting the arrival time of the vehicles according to the arrival time interval between the latest vehicle and the last vehicle and the current traffic conditions on several lines around the station, and establishing a bus arrival prediction time model by using the speeds of buses in multiple areas, predicting the predicted time when the vehicle arrives at the station under the normal condition and the time when the vehicle arrives at the station under the special condition according to areas, in order to reflect the running condition of the vehicle more accurately, when a certain vehicle arrives at a station, updating the arrival time interval between the vehicle and the previous vehicle. According to the method, a multi-area bus arrival time prediction algorithm based on the GPS is adopted to construct a bus arrival time prediction model, the feasibility is good, and interference of random factors is reduced.
本发明公开了一种基于公交车GPS计算车辆预计到达时间的算法,在基于GPS的公交站间行程时间调查数据的基础上,将若干个靠近站点的区域联动,根据最新车辆与上一辆车到站时间间隔和站点周围几条线路上的当前交通状况来预测车辆到达时间,利用多区域公交车辆速度建立公交到站预测时间模型;分区域预测车辆正常情况下达到站点的预测时间和车辆在特殊情况下到达站点的时间预测;为了更加准确地反映出车辆运行情况,当某一车辆到达站点时,对其与之前的车辆到站的时间间隔进行更新。本发明采用基于GPS的多区域公交车辆预计到达时间算法来构建公交到站时间预测模型,具有较好的可行性,降低了随机因素的干扰。
