A system for communicating traffic information, comprising:
- an information center that generates and prioritizes broadcast data messages regarding traffic data associated with a plurality of roads, the information center sending the prioritized broadcast data messages from a remote location to at least one vehicle traveling on a current route to a destination point;
- a database in communication with the information center, the database including information about the at least one vehicle's current route to the destination point;
- wherein the information center is configured to assign a priority rating to each broadcast data message based on the information about the at least one vehicle's current route to the destination point and is further configured to send each broadcast data message from the remote location to the at least one vehicle at a frequency determined based on the assigned priority rating;
- and
- wherein the information center is configured to send broadcast data messages having a higher priority rating more frequently than broadcast data messages having a lower priority rating.
A method for communicating traffic information from an information center located at a remote location to a vehicle traveling on a current route to a destination, comprising:
- retrieving information about the vehicle's current route to the destination point from a database;
- generating a broadcast data message including traffic data associated with at least one road;
- assigning a priority rating to the broadcast data message based on the information about the vehicle's current route to the destination point;
- sending the broadcast data message from the remote location to the vehicle at a frequency determined based on the assigned priority rating;
