Abstract
Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. The traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system. The user display may also automatically display traffic flow and traffic incident information for the direction that the user is traveling or along a route calculated by the navigation device. Further, a window displaying information about an upcoming traffic incident such as distance to the incident and incident details may automatically appear in the user display. Alternately, the user may select a roadway, freeway, or area for which traffic information is desired.
