Abstract
A system for identifying a fastest possible travel route is disclosed. A traveler data processor collects traffic speed data and associates the traffic speed data with road segments. The road segments collectively represent one or more possible travel routes from a start point to an end point. A forecast engine determines a predicted travel time for each of the road segments based on, for example, the traffic speed data for each of the road segments. A routing engine determines the fastest possible travel route from the start point to the end point. The fastest possible travel route is the possible travel route from the one or more possible travel routes with the shortest predicted travel time.
