The invention discloses a time-space diagram attention network traffic flow prediction method and system based on transmission perception, and relates to the technical field of traffic flow prediction, and the method comprises the steps: building a diagram structure set corresponding to a to-be-predicted region according to the spatial connection relation of an actual road network; acquiring traffic flow data of the to-be-predicted area in a first preset time length, and training a preset TAGAT-LSTM model by using the traffic flow data of the to-be-predicted area based on the graph structure set to obtain a target model which corresponds to the TAGAT-LSTM model and is trained; acquiring a historical traffic flow of the to-be-predicted region in a preset time length, and inputting the historical traffic flow into the target model for processing to obtain a predicted traffic flow of the to-be-predicted region in a future preset time length; through combination of three core modules in the TAGAT-LSTM model, the model can capture richer space-time dependency relationships, and the precision of traffic flow prediction is improved.
