Abstract
A feature for a navigation system that provides an evaluation of alternate routes. According to this feature, the navigation system compares the actual time of travel along a route to the estimated time of travel along the route. If the actual time of travel exceeds the estimated time of travel, alternate routes to the destination are calculated and provided to the user. This feature enables driver-experienced traffic conditions to be taken into account.
