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 preemption request  (Planned)  

Direct control signal or message to a signalized intersection that results in preemption of the current control plan and grants right–of–way to the requesting vehicle.

signal priority status  (Planned)  

In response to a request for signal priority, this flow indicates the status of the priority or preemption request.

vehicle location and motion  (Planned)  

Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
