The invention discloses a traffic flow prediction model construction method, a traffic flow prediction model use method and electronic equipment. The traffic flow prediction model construction method comprises the steps of performing EMD processing on collected traffic flow data to obtain a plurality of IMF components and margins; filtering the plurality of IMF components from high frequency to low frequency to obtain effective components; inputting the effective component and the margin into a training architecture for training, and obtaining a prediction model through supervised learning; wherein the training architecture comprises a plurality of training layers, the plurality of training layers comprise different activation functions, and the traffic flow data at least comprises the number of vehicles at a plurality of continuous intersections. According to the prediction model construction method provided by the invention, a plurality of continuous intersections are predicted and judged, the conditions of other intersections can be predicted according to the condition of one or more intersections, and various traffic problems are well solved.

    本申请公开了一种交通流量预测模型构建方法、使用方法及电子设备,包括:将采集的交通流量数据进行EMD处理后得到多个IMF分量和余量;以频率从高到底对多个IMF分量进行过滤,获得有效分量;将有效分量和余量输入至训练架构中进行训练,通过监督式学习获得预测模型;其中,训练架构包括多个训练层,多个训练层中包含不同的激活函数,交通流量数据至少包括多个连续路口的车辆数量。本申请的预测模型构建方法,对多个连续路口进行预测判断,能够根据一个或多个路口的情况对其他路口的情况进行预测,很好的解决各种交通问题。
