Information Flow Definitions

automated vehicle control parameters  (Planned)  

Information, instructions, and control parameters for automated vehicle operations including current system conditions and advisories, control parameters (e.g., speed, required vehicle performance profiles, gaps or headways) and check in/checkout instructions.

emergency traveler information  (Existing)  

Public notification of an emergency such as a natural or man–made disaster, civil emergency, or child abduction. This flow also includes evacuation information including evacuation instructions, evacuation zones, recommended evacuation times, tailored evacuation routes and destinations, traffic and road conditions along the evacuation routes, traveler services and shelter information, and reentry times and instructions.

restricted lanes information  (Planned)  

This flow defines the location, duration, and operating parameters for lanes that are reserved for the exclusive use of certain types of vehicles (e.g., transit vehicles) or vehicles that meet other qualifications (e.g., number of occupants, low emissions criteria). It identifies the lane(s), the start and stop locations, start and end times, vehicle restrictions, speed limits and platooning parameters.

speed management information  (Planned)  

Target speeds, speed advisories, and/or speed limit information provided to a vehicle. The information includes the current speed value(s), the route segment(s) and lane(s) where the speeds apply, and an indication of whether the speeds are suggested target speeds, posted advisory speeds, or enforceable speed limit values. This flow may also include information about the reason for reduced speeds and provide target lane information if lane changes are required.
