The invention provides a traffic flow prediction method, and belongs to the field of intelligent traffic. The method comprises the steps that a training set is acquired, the training set comprises period data and recent data, the period data is historical traffic data with weeks as periods, and the recent data is historical traffic data in recent time periods; wherein the traffic data comprises traffic flow, traffic speed and road occupancy; constructing a traffic flow prediction model, taking the periodic data and the recent data as the input of the traffic flow prediction model, and training the traffic flow prediction model to predict the traffic flow in a future time period; and collecting traffic data at the current moment, inputting the collected traffic data at the current moment into the trained traffic flow prediction model, and predicting the traffic flow in the future time period. According to the invention, the precision of the urban traffic flow prediction value can be improved.

    本发明提供一种交通流量预测方法,属于智能交通领域。所述方法包括:获取训练集,所述训练集包括:周期数据和近期数据,其中,周期数据为以周为周期的历史交通数据,近期数据为近期时间段的历史交通数据;其中,所述交通数据包括:交通流量、交通速度和道路占有率;构建交通流量预测模型,将周期数据和近期数据作为交通流量预测模型的输入,训练所述交通流量预测模型,以预测未来时间段的交通流量;采集当前时刻的交通数据,将采集的当前时刻的交通数据输入训练好的交通流量预测模型,预测未来时间段的交通流量。采用本发明,能够提高城市交通流量预测值的精度。
