Architecture Flow Definitions
commercial vehicle disable status (Planned) Applicable ITS Standards
This flow provides the status of the disable flag in the commercial vehicle.
commercial vehicle identities (Planned) 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.
container seal status (Planned) Applicable ITS Standards
The status of an electronic seal on a container, indicating sealing time, location, and authority, and any openings or tampering.
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 (Planned) Applicable ITS Standards
Notification to roadside (via transponder) of the presence and status of electronic cargo locks.
electronic lock data request (Planned) Applicable ITS Standards
Request from roadside for data regarding presence and status of electronic cargo locks.
electronic screening request (Planned) Applicable ITS Standards
Request for identification data to support electronic screening.
expected driver identity characteristics (Planned) Applicable ITS Standards
Driver identification information e.g., encrypted PIN codes issued to drivers, encrypted driver biometric parameters.
freight equipment information (Planned) 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.
intersection geometry (Planned) Applicable ITS Standards
The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.
intersection status (Planned) Applicable ITS Standards
Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.
local signal priority request (Planned) Applicable ITS Standards
Request from a vehicle to a signalized intersection for priority at that intersection. This flow also allows the vehicle to cancel a priority request (for example, when the vehicle clears the intersection).
on-board safety data (Planned) 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 (Planned) Applicable ITS Standards
Command to commercial vehicle to pull into or bypass inspection station.
safety inspection record (Planned) Applicable ITS Standards
Record containing results of commercial vehicle safety inspection.
safety inspection request (Planned) Applicable ITS Standards
Request for safety inspection record.
screening event record (Planned) Applicable ITS Standards
Results of CVO electronic screening activity.
signal priority status (Planned) Applicable ITS Standards
In response to a request for signal priority, this flow indicates the status of the priority or preemption request.
trigger area notification (Planned) Applicable ITS Standards
Notification to activate wireless roadside inspection safety data message collection.
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 location and motion (Planned) Applicable ITS Standards
Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory.
