A method for utilizing a trip history of a vehicle during a trip from an original position to a destination includes: (a) determining the original position; (b) comparing the original position to a mapping database covering the trip; (c) determining a road segment of the mapping database associated to the original position; (d) determining a current position during the trip; (e) comparing the current position to the mapping database; (f) determining a road segment of the mapping database associated to the current position; (g) setting the road segment as a link of the trip; (h) repeating (e)-(g) until the destination is reached; (i) determining the destination; (j) comparing the destination to the mapping database; (k) determining a road segment of the mapping database associated to the destination; and (l) representing the trip as connected links between the original position and destination, each link corresponding to a road segment.
A destination prediction system comprising a prediction unit for predicting a destination for a vehicle, the prediction unit being configured to obtain information of a current location of the vehicle and associating the current location with a current link in stored trip data comprising information of origin cluster, destination cluster and/or a series of connected links between the origin cluster and the destination cluster and probabilities for next links given a current link, to update the probabilities for next links during a trip based on a selection of a link by a user of the vehicle, and to, based on statistical properties of the current link and the stored trip data, provide a destination prediction for the vehicle including a prediction of the next link where it is possible to select between two or more alternative next links, wherein to provide the destination prediction the prediction unit is configured to handle missing data and use statistical models for prior information rather than directly use observations, adjust weights for different conditions to improve predictability, and adapt for sequentially increasing data, the prediction unit further configured to provide the destination prediction to a navigation device to provide navigation directions to a user based on the destination prediction, wherein a trajectory of the vehicle is controlled based on the navigation directions and the destination prediction.
