A vehicle location prediction process comprises: receiving data indicating position and velocity of a vehicle at time points during a time window; using the data to calculate a path travelled by the vehicle; and determining whether the path indicates a change of direction of the vehicle. When the path indicates a change of direction, the location of the vehicle at a future time is estimated using, in addition to the received position and velocity data at the end of the time window, a classification obtained by determining the similarity of the calculated path to at least one vehicle path corresponding to a vehicle preparing to turn and at least one vehicle path corresponding to a vehicle not preparing to turn, and, in accordance with the result of the similarity determination, classifying the calculated path either as that of a vehicle preparing to turn or a vehicle not preparing to turn.
