Information Flow Definitions

broadcast advisories  (Existing)  

General broadcast advisories that are provided over wide–area wireless communications direct to the vehicle radio. These analog advisory messages may provide similar content to ITS broadcast information flows, but include no digital data component. Existing Highway–Advisory Radio (HAR) advisory messages are a prime example of this flow.
