Vehicle OBE --> Emergency Vehicle OBE:
vehicle location and motion
Definitions
vehicle location and motion (Information Flow): Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
Vehicle OBE (Source Physical Object): The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications.
In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles.
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. | False information here could lead to a false warning, or not receiving a warning when an infraction is about to occur. 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. If a warning is not sent due to incorrect data, there are also many other visual indictors that should stop a driver from causing an infraction. | 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. |
