Training method of vehicle trajectory prediction model and vehicle jam prediction method

The invention relates to the technical field of vehicles, in particular to a training method of a vehicle trajectory prediction model and a vehicle jam prediction method. According to the embodiment of the invention, the original data comprises the driving data of the two vehicles generating the plugging interaction behavior and also comprises the driving data of the vehicle not generating the plugging interaction behavior, so that the driving data of the vehicle generating the plugging interaction behavior needs to be screened out from the original data, and then the driving data of the vehicle generating the plugging interaction behavior is obtained on the basis of the original plugging data. According to the method and the device, the plugging data is expanded to increase the quantity of the plugging data, and then the plugging data with the increased quantity is put into the original data to obtain new original data, so that the proportion of the plugging scene data in the new original data is enriched, t
