Architecture Flow Definitions
conflict monitor status (Planned) Applicable ITS Standards
A control flow that supports failsafe operation in the event that a conflict is detected that requires the RSE to enter a failsafe operating mode.
intersection control status (Planned) Applicable ITS Standards
Status data provided by the traffic signal controller including phase information, alarm status, and priority/preempt status.
intersection status monitoring (Planned) Applicable ITS Standards
Current signal phase and timing information for all lanes at a signalized intersection. This flow represents monitoring of communications by a receiver at the intersection to support monitoring for conflicts between actual signal states and RSE communications about those states.
signal priority service request (Planned) Applicable ITS Standards
A service request for vehicle priority issued to a traffic signal controller that results in green extension or other accommodation for the priority vehicle, within the current signal timing plan. The request includes the priority level, the desired time and duration of service, and the intended travel path through the intersection. This flow also allows the RSE to cancel a previously issued request for priority.
