Information Flow Definitions
intersection status (Planned)
Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.
local signal priority request (Planned) Selected Comm Solution
Request from a vehicle to a signalized intersection for priority at that intersection. This flow also allows the vehicle to cancel a priority request (for example, when the vehicle clears the intersection).
vehicle location and motion (Planned)
Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
