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.
vehicle signage data (Existing) Selected Comm Solution
In–vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., local traffic and road conditions, restrictions, vehicle requirements, work zones, detours, closures, advisories, and warnings).
