Remote EV OBEs --> Emergency Vehicle OBE:
work zone warning notification

This triple is bi-directional. See also Emergency Vehicle OBE --> Remote EV OBEs: work zone warning notification

Definitions

work zone warning notification (Information Flow): Notification of a work zone emergency or safety issue. This flow identifies that a work zone emergency or safety issue has occurred so that warnings may be generated by more than one system in the work zone.

Remote EV OBEs (Source Physical Object): This represents on-board equipment on remote emergency (e.g., law enforcement, fire, EMS, towing and recovery) vehicles. It provides a source and destination for ITS information transfers between emergency vehicles. These information transfers allow information to be shared between emergency vehicles arriving, or involved at, an incident. Vehicle to vehicle communications at incident locations facilitates incident coordination and personal safety.

Emergency Vehicle OBE (Destination 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.

This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. This information should be accurate, but an incorrect information should not have a direct impact causing the loss of life or limb. The system should be able to operate properly if it misses a few messages. If a message is not received, the emergency vehicle OBE should know.
