ABSTRACT:
The present invention is a method and an apparatus for predicting future travel times over a transportation network. In one embodiment, a method for predicting future travel times over a transportation network includes receiving a data point indicating a real-time volume of traffic on the link at a given time and updating a template representative of an observed traffic pattern on the link in accordance with the received data point. A future travel time over the link can then be estimated in accordance with the updated template. Thus, the template is able to adapt to dynamically changing traffic patterns, taking these changing traffic patterns into account when making predictions of future traffic patterns.
