Abstract
System and methods for determining and disseminating current traffic information and/or route information are presented. For example, in accordance with one embodiment of the present invention, traffic condition information is collected from mobile units that provide their location or position information. The traffic condition may be determined, for example, based on the difference between the velocity of each mobile unit and the speed limit corresponding to their location. Furthermore, the fastest routes between two locations may be determined and provided based on historical and/or current conditions and provided to a mobile unit. In accordance with another embodiment of the present invention, route information may be utilized to determine whether a mobile unit (e.g., associated with a vehicle) is allowed or prohibited from traveling along a certain route.
