Some embodiments of the invention provide a navigation application that uses a novel traffic notification scheme for providing traffic related notifications during a navigation presentation that is provided by a device. While providing a navigation presentation, the application iteratively monitors traffic conditions along the route. When traffic conditions meet a set of one or more threshold criteria, the application identifies a type of traffic notification that it should provide from several possible traffic notifications types. Next, without receiving any input from outside of the device, the application provides a traffic notification that is associated with the selected traffic notification type. In some embodiments, the traffic notification types include a notification (1) relating to traffic congestion along the current route, (2) relating to one or more faster routes that can replace the current route, and (3) regarding a road closure or extreme delay along the current route.

Traffic notifications during navigation

Live traffic routing in a mobile navigation system generates alternate routes based on the user's current location, live traffic conditions and estimated time of arrival at certain locations along the route. Live traffic routing re-ranks alternate routes taking into account which routes offer the best cost path to the user's destination.
