The invention discloses a short-time traffic flow prediction method and system, and the method comprises the steps: converting the GPS data of a ship into the data of traffic flow, carrying out the aggregation according to a certain time scale, obtaining a traffic flow sequence {V1, V2, V3,... Vm} of each monitoring point at a time interval of T, and m being the number of monitoring points; wherein the traffic flow sequence Vi of the to-be-predicted monitoring point pi is equal to {vi, 1, vi, 2, vi, 3,..., vi, n}, and n is the number of time intervals; and inputting the traffic flow sequence of the monitoring point pi to be predicted into a pre-trained traffic flow prediction model, and outputting the traffic flow vi, n + 1 of the monitoring point pi in the next time interval T. The methodprovided by the invention is high in prediction accuracy of the future dynamic traffic flow.

    本发明公开了一种短时交通流预测方法及系统,所述方法包括:将船舶的GPS数据转换为交通流量的数据,并按照一定的时间尺度进行聚集,得到各个监测点以T为时间间隔的交通流序列{V,V,V,…Vm},m为监测点数量;待预测监测点p的交通流序列为V={v,v,v,…,v},n为时间间隔的个数;将待预测监测点p的交通流序列输入预先训练好的交通流预测模型,输出监测点p在下一个时间间隔T内的交通流v。本发明的方法对于未来动态交通流的预测的准确率较高。
