Architecture Flow Definitions
environmental situation data (Planned) Applicable ITS Standards
Aggregated and filtered vehicle environmental data collected from vehicle safety and convenience systems including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti-lock brake status, and other collected vehicle system status and sensor information. This information flow represents the aggregated and filtered environmental data sets that are provided by the RSE to the back office center. Depending on the RSE configuration and implementation, the data set may also include environmental sensor station data collected by the RSE.
intersection control status (Planned) Applicable ITS Standards
Status data provided by the traffic signal controller including phase information, alarm status, and priority/preempt status.
mixed use crossing status (Planned) Applicable ITS Standards
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) Applicable ITS Standards
Pedestrian, bicyclist, and other non-motorized user locations at an intersection as detected and reported by an RSE.
signal service request (Planned) Applicable ITS Standards
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) Applicable ITS Standards
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.
