The invention provides a traffic flow prediction method and device, a readable storage medium and an electronic device, and the method comprises the steps: determining the periodic time offset of a to-be-predicted road segment based on the obtained time attribute information of the to-be-predicted time period, the road attribute information of the to-be-predicted road segment and the environment prediction information; determining a current prediction time window and a historical time window based on the period time offset and the to-be-predicted time period; based on the road network information of the road network area where the to-be-predicted road section is located, the current prediction time window, the historical prediction time window and the historical traffic data of the road network area, constructing a dynamic spatial-temporal feature matrix of the to-be-predicted road section; and inputting the dynamic spatial-temporal feature matrix into a trained traffic flow predictionmodel to obtain the predicted traffic flow of the to-be-predicted road section in the to-be-predicted time period. Thus, the traffic flow is predicted by using the dynamic spatial-temporal feature matrix, more comprehensive reference data can be provided for traffic flow prediction, and the accuracy of traffic flow prediction can be improved.
本申请提供了交通流量的预测方法、装置、可读存储介质及电子设备,基于获取到的待预测时间段的时间属性信息、待预测路段的道路属性信息以及环境预测信息,确定待预测路段的周期时间偏移量;基于周期时间偏移量和待预测时间段,确定当前预测时间窗口,以及历史时间窗口;基于待预测路段所在路网区域的路网信息、当前预测时间窗口、历史预测时间窗口以及路网区域的历史交通数据,构建待预测路段的动态时空特征矩阵;将动态时空特征矩阵输入至训练好的交通流量预测模型中,得到待预测路段在待预测时间段的预测交通流量。这样,利用动态时空特征矩阵对交通流量进行预测,可以为交通流量预测提供更全面的参考数据,有助于提高交通流量预测的准确性。
