PREDICTING DEVICE, VEHICLE SYSTEM, AND STORAGE MEDIUM

A predicting device includes: a recognizer configured to recognize a state of a moving body; a predictor configured to predict a position of the moving body in the future on the basis of the recognition result of the recognizer; and a processor configured to determine whether to set a first risk region or a second risk region larger than the first risk region for the moving body on the deviation between a position of the moving body which has been recognized by the recognizer and a position of the moving body in the future which has been predicted previously by the predictor.
