METR System --> Maint and Constr Vehicle OBE:
METR management information

Definitions

METR management information (Information Flow): If the rule is to be distributed through a specialized vehicle OBE, the METR input device configures and monitors the OBE using the METR management info. While the content of this flow is similar to a combination of the "METR application information" flow and the "METR application status" flow, the mobile nature of the OBE results in different communication characteristics, which results in a different flow.

METR System (Source Physical Object): The 'METR System' creates and maintains electronic versions of traffic rules, regulations, ordinances and statutes that have official status and must be understood by all motor vehicle operators and intelligent vehicles that operate at higher automation levels. This system represents multiple authorities that operate at local, regional, state, and national levels and represents organizations that establish, manage, and enact the traffic code. Each electronic rule is approved, signed, and traceable to a specific rule-maker. Rules are independently verified. Any identified or reported rule discrepancies are analyzed, investigated, and addressed.

Maint and Constr Vehicle OBE (Destination Physical Object): The 'Maint and Constr Vehicle OBE' resides in a maintenance, construction, or other specialized service vehicle or equipment and provides the processing, storage, and communications functions necessary to support highway maintenance and construction. All types of maintenance and construction vehicles are covered, including heavy equipment, supervisory vehicles, unmanned remote controlled field maintenance robots, and sensory platforms that may be wheeled or low altitude aerial vehicles (e.g. drones, balloons). The MCV OBE provides two-way communications between drivers/operators and dispatchers and maintains and communicates current location and status information. A wide range of operational status is monitored, measured, and made available, depending on the specific type of vehicle or equipment. A snow plow for example, would monitor whether the plow is up or down and material usage information. The Maint and Constr Vehicle OBE may also contain capabilities to monitor vehicle systems to support maintenance of the vehicle itself. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including maintenance and construction vehicles. The Maint and Constr Vehicle OBE supplements these general capabilities with capabilities that are specific to maintenance and construction vehicles.
