The invention provides a traffic situation prediction method, device and equipment based on a space-time attention mechanism. The method comprises the following steps: acquiring traffic flow data corresponding to each traffic sensing node in a to-be-predicted traffic road network in a historical period; through a pre-trained traffic situation deduction model, space-time embedding representation corresponding to the to-be-predicted traffic road network is extracted, and a traffic situation prediction result corresponding to the to-be-predicted traffic road network is generated based on the traffic flow data and the space-time embedding representation; wherein the traffic situation deduction model is obtained by training a dense connection space-time multi-head attention model combining a space-time attention mechanism and a conversion attention mechanism, and the traffic situation prediction result comprises traffic flow data corresponding to each traffic sensing node in a prediction period. According to the method, the traffic situation prediction precision under the traffic situation deduction scene of the multiple sensing nodes is greatly improved.
