The invention relates to the technical field of traffic, and provides a traffic state and driving style fused trajectory prediction method and related equipment, and the method comprises the steps: carrying out the clustering of adjacent vehicles based on the historical trajectory of the adjacent vehicles for each adjacent vehicle, and obtaining the driving style of the adjacent vehicles; acquiring the traffic state of each target vehicle according to the historical tracks of all target vehicles; according to the traffic states of all the target vehicles and the driving styles of all the adjacent vehicles, track prediction is carried out on each target vehicle by using a prediction model, and a plurality of prediction tracks of each target vehicle are obtained; constructing a prediction loss function by using all the prediction trajectories, and training the prediction model by using the prediction loss function to obtain a final prediction model; and performing trajectory prediction on the to-be-predicted vehicle by using the final prediction model to obtain a final prediction trajectory of the to-be-predicted vehicle. According to the method, the accuracy of trajectory prediction can be improved.
