The invention provides a spatial-temporal feature fusion traffic flow prediction method and device, equipment and a storage medium, and relates to the field of traffic flow prediction, and the method comprises the steps: obtaining a traffic data set comprising a plurality of traffic influence factors in a preset time period every preset time period; constructing a graph structure of a plurality of data nodes based on the plurality of traffic influence factors, loading the traffic data set into the graph structure, and preprocessing the traffic data set loaded into the graph structure to obtain a target traffic data set; inputting the target traffic data set into a pre-configured prediction model to obtain traffic data spatial-temporal characteristics; the pre-configured prediction model comprises a space representation module, a time representation module and a full connection layer; the traffic data spatial-temporal characteristics are used for expressing distribution characteristics of traffic flow; according to the method, the spatial-temporal characteristics of the traffic data are visually displayed to analyze the traffic flow, so that the spatial-temporal characteristics of the data are extracted through mutual fusion of the two representation modules, and the prediction accuracy is improved.

    本申请提供一种时空特征融合交通流预测方法、装置、设备及存储介质,涉及交通流预测领域,方法包括:每隔预设时间段,获取预设时间段内的包括多个交通影响因素的交通数据集;基于多个交通影响因素构建多个数据节点的图结构,并将交通数据集载入图结构,对载入图结构的交通数据集进行预处理,得到目标交通数据集;将目标交通数据集输入预配置的预测模型中,得到交通数据时空特征;预配置的预测模型包括空间表征模块、时间表征模块以及全连接层;交通数据时空特征用于表述交通流的分布特征;将交通数据时空特征进行可视化显示,以进行交通流的分析,这样,通过以上两种表征模块的相互融合,用以提取数据时空特征,提高预测的准确性。
