The invention discloses a traffic flow prediction method, and the method comprises the steps: transmitting a local initial model to a plurality of prediction terminals; obtaining target shared data sent by a plurality of prediction terminals, and clustering the target shared data sent by the plurality of prediction terminals to obtain a plurality of clustering data; generating a global parameter according to the plurality of clustering data; updating the local initial model by utilizing the global parameters to obtain a global updating model; and sending the global update model to the prediction terminal, so that the prediction terminal performs traffic flow prediction by using the global update model and outputs a prediction result. According to the method, under the condition that privacy protection constraints are not damaged, the algorithm complexity is reduced, and meanwhile, the traffic flow can be accurately predicted.

    本发明公开了交通流量的预测方法,其中,该方法包括:向多个预测终端发送本地初始模型;获取多个预测终端发送的目标共享数据,根据多个预测终端发送的目标共享数据聚类得到多个聚类数据;根据多个聚类数据生成全局参数;利用全局参数更新本地初始模型得到全局更新模型;将全局更新模型发送给预测终端,以使得预测终端利用全局更新模型进行交通流量预测输出的预测结果。本发明可以在不损害隐私保护约束的条件下,降低算法复杂度的同时还能实现精确预测交通流。
