The invention provides a vehicle arrival time prediction method and device, computer equipment and a storage medium, and belongs to the technical field of traffic prediction. The method is used for accurately predicting all vehicles possibly reaching a destination and arrival time of the vehicles reaching the destination at a destination end. The method comprises the following steps of: acquiringdriving track data of each vehicle according to a GPS data packet sent by the vehicle; calculating the probability that the corresponding vehicle arrives at the same preset destination; determining the vehicles of which the calculated probabilities are greater than a preset probability threshold as alternative arrival vehicles; calculating the predicted arrival time of each alternative arrival vehicle; selecting a first preset number of vehicles with a maximum probability in a preset time interval with the current time from the alternative arrival vehicles as final arrival vehicles, and acquiring predicted arrival time of the final arrival vehicles; calculating the congestion time between the finally arrived vehicles and the destination in real time; and calculating the final arrival timeof the final arrival vehicles according to the predicted arrival time, the congestion time and a weight coefficient.
本申请提供车辆到达时间的预测方法、装置、计算机设备及存储介质,属于交通预测技术领域。用于在目的地端对所有可能到达该目的地的车辆及到达该目的地的到达时间进行准确预测。该方法包括:根据车辆发出的GPS数据包获取每个车辆的行驶轨迹数据;计算对应车辆到达预设的同一目的地的概率;将计算的该概率大于预设概率阈值的车辆确定为备选到达车辆;计算每个备选到达车辆的预测到达时间;从该备选到达车辆中选取与当前时间相隔预设时间段内该概率最大的前预设个车辆作为最终到达车辆,获取该最终到达车辆的预测到达时间;实时计算该最终到达车辆与该目的地之间的拥堵时间;根据预测到达时间、拥堵时间及权重系数计算该最终到达车辆的最终到达时间。
