Emergency Vehicle OBE --> Emergency 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.

Emergency Vehicle OBE (Source Physical Object): The Emergency Vehicle On-Board Equipment (OBE) resides in an emergency vehicle and provides the processing, storage, and communications functions that support public safety-related connected vehicle applications. It represents a range of vehicles including those operated by police, fire, and emergency medical services. In addition, it represents other incident response vehicles including towing and recovery vehicles and freeway service patrols. It includes two-way communications to support coordinated response to emergencies. In CVRIA, a separate 'Vehicle OBE' physical object supports the general V2V and V2I safety applications and other applications that apply to all vehicles, including emergency vehicles. The Emergency Vehicle OBE supplements these general capabilities with capabilities that are specific to emergency vehicles.

Emergency Personnel (Destination Physical Object): 'Emergency Personnel' represents personnel that are responsible for police, fire, emergency medical services, towing, service patrols, and other special response team (e.g., hazardous material clean-up) activities at an incident site. These personnel are associated with the Emergency Vehicle during dispatch to the incident site, but often work independently of the Emergency Vehicle while providing their incident response services.

This is directly observable data. A few false warnings should not have a bad consequence. When an emergency personnel receives 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 emergency personnel can rely on it.
