electronic screening request (Existing) Applicable ITS Standards
Request for identification data to support electronic screening.
environmental sensor data (Planned) Applicable ITS Standards
Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
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.
expected driver identity characteristics (Existing) Applicable ITS Standards
Driver identification information e.g., encrypted PIN codes issued to drivers, encrypted driver biometric parameters.
freight equipment information (Existing) Applicable ITS Standards
Container, trailer, or chassis information regarding identity, type, location, brake wear data, mileage, seal #, seal type, door open/close status, chassis bare/covered status, tethered / untethered status, temperature, humidity, power, battery levels, brake wear data, and bill of lading/information regarding the cargo/content.
incident scene warning notification (Planned) Applicable ITS Standards
Notification of an incident scene emergency or safety issue. This flow identifies that an incident scene emergency or safety issue has occurred so that warnings may be generated by more than one system in the work zone.
infrastructure monitoring sensor control (Existing) Applicable ITS Standards
Data used to configure and control infrastructure monitoring sensors.
infrastructure monitoring sensor data (Existing) Applicable ITS Standards
Data read from infrastructure–based sensors that monitor the condition or integrity of transportation infrastructure including bridges, tunnels, interchanges, pavement, culverts, signs, transit rail or guideway, and other roadway infrastructure. Includes sensor data and the operational status of the sensors.
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 infringement info (Planned) Applicable ITS Standards
Vehicle path information sent by a vehicle that is violating the stop bar at an intersection. This flow includes the vehicle's position, heading, speed, acceleration, transmission, steering–wheel angle, braking status, size information and trajectory.
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.
on-board safety data (Existing) Applicable ITS Standards
Safety data measured by on–board sensors. Includes information about the vehicle, vehicle components, cargo, and driver. The query flow is not explicitly shown.
pass/pull-in (Existing) Applicable ITS Standards
Command to commercial vehicle to pull into or bypass inspection station.
reduced speed warning info (Planned) Applicable ITS Standards
Real time notification of vehicle detections, measured vehicle characteristics (e.g., vehicle height), speed measurements, and warnings issued by roadway infrastructure. This flow can also include roadway configuration data, current speed limits, and warning parameters and thresholds enabling local speed management application configuration and management.
restricted lanes application status (Planned) Applicable ITS Standards
Current RSE application status that is monitored by the back office center including the operational state of the RSE, current configuration parameters, and a log of lane use (aggregate profiles of vehicles that checked in to the lane and reported vehicle speeds in the lanes) and RSE communications activity.
safety inspection record (Existing) Applicable ITS Standards
Record containing results of commercial vehicle safety inspection.
safety inspection request (Existing) Applicable ITS Standards
Request for safety inspection record.
screening event record (Existing) Applicable ITS Standards
Results of CVO electronic screening activity.
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.
traffic gap information (Planned) Applicable ITS Standards
Measured gap to the next approaching vehicle per lane and direction of travel
traffic situation data (Existing) 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.
unique identifiers (Planned) Applicable ITS Standards
Unique identifiers for the motor carrier, driver, and vehicle. This flow identifies the driver actually operating the vehicle in multi–driver scenarios.
vehicle entries and exits (Planned) Applicable ITS Standards
Information exchanged between an RSE and ITS Roadway Equipment that supports detection of non–equipped vehicles in an automated lane, low emissions zone, or other facility where V2I communications is used to monitor vehicles at entry or exit points. This exchange also supports identification of non–equipped vehicles where an RSE is used for payment collection. This generic exchange can be implemented by any approach that compares vehicle detections with V2I communications by the RSE to identify vehicles that are not equipped or are otherwise unable to communicate with the RSE.
vehicle signage local data (Planned) Applicable ITS Standards
Information provided by adjacent field equipment to support in–vehicle signing of dynamic information that is currently being displayed to passing drivers. This includes the dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, parking availability, etc.) and control parameters that identify the desired timing, duration, and priority of the signage data.
work zone warning notification (Existing) Applicable ITS Standards
Notification of a work zone emergency or safety issue. This flow identifies that a work zone emergency or safety issue has occurred so that warnings may be generated by more than one system in the work zone.
