Abstract
A process includes receiving data indicating position and velocity of a vehicle at time points during a time window; using the data to calculate a path of movement by the vehicle; and determining whether the path indicates a change in a direction of movement of the vehicle. When the calculated path indicates a change in the direction, the location of the vehicle at a future time relative to the time window is estimated using the received position and velocity data at end of the time window, and a classification based on a similarity of the calculated path to at least one vehicle path corresponding to a vehicle preparing to turn and to at least one vehicle path corresponding to a vehicle not preparing to turn, and based on the similarity, classifying the calculated path either as that of a vehicle preparing to turn or a vehicle not preparing to turn.
