The invention discloses a traffic flow prediction method and device, a storage medium and computer equipment. The method comprises the following steps: respectively acquiring traffic demand position information, traffic start and end point position information, traffic demand position map structure data and traffic start and end point map structure data in a plurality of preset historical time periods; receiving the traffic demand position information and the traffic demand position map structure data through the model to obtain a traffic demand spatial-temporal feature vector; combining the traffic demand spatial-temporal feature vector into traffic start-end point diagram structure data, and receiving the traffic start-end point diagram structure data and the traffic start-end point position information through a model to obtain a start-end point demand spatial-temporal feature vector; and fusing the start-end point demand spatial-temporal feature vector and the traffic demand spatial-temporal feature vector to obtain a start-end point flow prediction feature vector, and determining a traffic flow prediction value in the prediction time period based on the start-end point flow prediction feature vector. According to the method, the prediction accuracy of the traffic flow can be improved.

    本发明公开了一种交通流量预测方法、装置、存储介质及计算机设备。其中方法包括:分别获取多个预设历史时间段内的交通需求位置信息、交通起止点位置信息、交通需求位置图结构数据和交通起止点图结构数据;通过模型接收交通需求位置信息和交通需求位置图结构数据以得到交通需求时空特征向量;将交通需求时空特征向量合并到交通起止点图结构数据中,并通过模型接收交通起止点图结构数据和交通起止点位置信息以得到起止点需求时空特征向量;将起止点需求时空特征向量和交通需求时空特征向量进行融合,得到起止点流量预测特征向量,并基于起止点流量预测特征向量确定在预测时间段的交通流量预测值。上述方法能提高对交通流量的预测准确性。
