Maint and Constr Vehicle OBE --> Maint and Constr Field Personnel:
work zone warning
Definitions
work zone warning (Information Flow): Warnings provided to field personnel, indicating a work zone emergency or safety issue such as the intrusion of a vehicle into the work zone area or movement of personnel into the travel lanes.
Maint and Constr Vehicle OBE (Source 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.
Maint and Constr Field Personnel (Destination Physical Object): Represents the people that perform maintenance and construction field activities including vehicle and equipment operators, field supervisory personnel, field crews, and work zone safety personnel. Information flowing from the Maintenance and Construction Field Personnel will include those system inputs specific to maintenance and construction operations, such as information regarding work zone status, or the status of maintenance actions. The field personnel are also monitored within the work zone to enhance work zone safety. Information provided to Maintenance and Construction Field Personnel includes dispatch requests, maintenance and construction actions to be performed, and work zone safety warnings.

| Interoperability | Description |
|---|---|
| Not Applicable | Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability. |

| Basis | This is directly observable data. | A few false warnings should not have a bad consequence. When field personnel receive a warning they can look around and verify whether or not a vehicle is actually headed towards them. | It would be better to receive any messages than to not have this application available due to availability requirements. However, the higher the availability here, the more useful the application will be and the more field personnel can rely on it. | |
