Interface: CVO Inspection Station - NDOT Statewide Field Equipment
Architecture Flow Definitions
barrier system control (Planned) Applicable ITS Standards
Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.
barrier system status (Planned) Applicable ITS Standards
Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.
commercial vehicle disable status (Existing) Applicable ITS Standards
This flow provides the status of the disable flag in the commercial vehicle.
commercial vehicle identities (Existing) Applicable ITS Standards
Identification information for the Commercial Vehicle (e.g., license plate number or USDOT number), Freight Equipment (e.g., container, chassis, or trailer identification), Carrier, and Driver.
driver log (Planned) Applicable ITS Standards
A daily log showing hours in service for the current driver. The query flow is not explicitly shown.
electronic lock data (Existing) Applicable ITS Standards
Notification to roadside (via transponder) of the presence and status of electronic cargo locks.
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.
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.
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.
traffic gap information (Planned) Applicable ITS Standards
Measured gap to the next approaching vehicle per lane and direction of travel
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.
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 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.
wrong way vehicle detected (Planned)
Notification that a vehicle has been detected traveling in the wrong direction. This can be a direct report by an equipped vehicle that is being driven in the wrong direction or a report of a non–equipped vehicle that has been detected traveling in the wrong direction. It includes the current location, speed, acceleration, and heading of the wrong way vehicle.
