Interface: KYTC Traffic Signals - KYTC Connected Vehicle Roadside Equipment
Information Flow Definitions
conflict monitor status (Planned)
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)
Status data provided by the traffic signal controller including phase information, alarm status, and priority/preempt status.
intersection status monitoring (Planned)
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.
mixed use crossing status (Planned)
Current pedestrian and other mixed use crossing information including an indication of whether the call button has been activated, the current state of the mixed use crossing signal, and information indicating whether non–motorized users are currently occupying the cross walk.
personal location information (Planned)
Pedestrian, bicyclist, and other non–motorized user locations at an intersection as detected and reported by an RSE.
signal service request (Planned)
A call for service or extension for a signal control phase that is issued by the RSE for connected vehicles approaching an intersection and/or pedestrians at a crosswalk. This flow identifies the desired phase and service time.
traffic situation data (Planned)
Current, aggregate traffic data collected from connected vehicles that can be used to supplement or replace information collected by roadside traffic detectors. It includes raw and/or processed reported vehicle speeds, counts, and other derived measures. Raw and/or filtered vehicle control events may also be included to support incident detection.
