The embodiment of the invention relates to a predicted trajectory processing method and device. The method comprises the following steps: acquiring a first historical trajectory, a first position and a first driving sign of an obstacle vehicle; determining a trajectory prediction mode type and a corresponding trajectory prediction mode number at the current moment according to the first driving sign; when the trajectory prediction mode type is a single mode type, calling N single trajectory prediction models to perform single trajectory prediction, and performing trajectory fusion on the N first prediction trajectories to generate a first fusion trajectory; when the trajectory prediction modal type is a multi-modal type, calling M multi-trajectory prediction models to perform multi-trajectory prediction to generate first prediction trajectory sets, and performing trajectory fusion on the M first prediction trajectory sets to generate a first fusion trajectory set; and performing prediction data integration on the obtained first fusion trajectory or the first fusion trajectory set according to the trajectory prediction mode type to generate prediction trajectory data and output the prediction trajectory data. According to the invention, the prediction accuracy can be improved.
