The invention discloses a traffic flow prediction method and device based on a space-time sequence, a storage medium and computing equipment. The method comprises the following steps: training a traffic flow prediction model in advance; and obtaining the traffic flow at the current moment, inputting the traffic flow into the traffic flow prediction model, and predicting to obtain the traffic flow at the future moment. Wherein the traffic flow prediction model comprises a plurality of space-time blocks and a prediction module, and each space-time block comprises a space-time attention mechanism module which is used for extracting spatial correlation characteristics and temporal correlation characteristics of input traffic flow data; and the space-time convolution module is used for extracting space features and time features of the traffic flow data. The prediction method not only can provide high-accuracy traffic volume prediction and predict the effective change condition of the traffic flow, but also has low requirements on hardware and implementation cost and is easy to deploy and implement.
