Abstract

An originating navigation device sends an alert location to a recipient navigation device over a wireless network. The originating navigation device is operable to classify the alert location (e.g. traffic accident) and associate additional data. The recipient navigation device receives the alert location and may plan an alternative route, which circumnavigates the alert location. Further, if the recipient navigation device already has a route selected, the recipient navigation device may determine the estimated delay caused by the alert condition occurring at the alert location. The recipient device may apply filtering rules in order to screen out undesired alert locations sent by the originating navigation device.
