host emergency vehicle status Quintuple

Bidirectional?: False

host emergency vehicle status (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'EV On-Board En Route Support' application object and the 'Emergency Vehicle Databus' physical object. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'host emergency vehicle status'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Emergency Vehicle Databus' to 'Emergency Vehicle OBE'.

Emergency Vehicle Databus (Source Physical Object): The 'Emergency Vehicle Databus' represents the vehicle databus that interfaces with on-board equipment on a public safety vehicle. It is a specialized and extended form of the Vehicle Databus that may be subject to different vehicle databus standards and hosts a broad range of components that are specific to emergency vehicles including the lightbar/siren and on-board apparatus that supports law enforcement, firefighting, and emergency medical services. As a specialized form of the Vehicle Databus, it also provides access to the general-purpose sensors (e.g., radars, cameras), GPS, drive train monitoring and control systems, and vehicle safety features that support connected vehicle applications. In CVRIA, the 'Emergency Vehicle Databus' is used to represent the onboard interactions between the Emergency Vehicle OBE and the other systems included in a host emergency vehicle.

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.

EV On-Board En Route Support (Destination Application Object): "EV On-Board En Route Support" provides communications functions to responding emergency vehicles that reduce response times and improve safety of responding public safety personnel and the general public. It supports traffic signal preemption via short range communication directly with signal control equipment and sends alert messages to surrounding vehicles.
