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.

 

intersection status   (Planned)  

Status of intersection congestion, approaching vehicles, etc.

 

vehicle signage data   (Planned)  

In-vehicle signage data generated by the roadway infrastructure indicating either road conditions, street names, or special information.
