Emergency Vehicle OBE --> Traffic Management Center:
emergency vehicle tracking data
Definitions
emergency vehicle tracking data (Information Flow): The current location and operating status of the emergency vehicle.
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. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including emergency vehicles. The Emergency Vehicle OBE supplements these general capabilities with capabilities that are specific to emergency vehicles.
Traffic Management Center (Destination Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.

Basis | Emergency Vehicles give obvious visual and audio indicators about their location and operating status. Knowing the location of every single emergency vehicle within a city could be extremely useful information to a criminal. Additionally, although this is observable data, it is transmitted on a regional level, which means that someone who is able to intercept it would be able to read the location of all emergency vehicles, not just the ones they could directly observed. A sufficiently motivated criminal can however get this information by other means. | Incorrect data here could lead to incorrect decisions being made about the closure of lanes, or incorrect information being shared with the emergency vehicles. There should be other indicators that would contradict incorrect information transmitted here. | This information may be used to determine which emergency vehicle is dispatched, and having this information available could lead to a quicker response from the emergency vehicle. However, the system would still be able to operate properly if only most messages make it through. |
