decision support information Quintuple

Bidirectional?: True

decision support information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'EV On-Board Incident Management Communication' application object and the 'Remote EV OBEs' 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 'decision support information'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

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.

EV On-Board Incident Management Communication (Destination Application Object): "EV On-board Incident Management Communication" provides communications support to first responders. Information about the incident, information on dispatched resources, and ancillary information such as road and weather conditions are provided to emergency personnel. Emergency personnel transmit information about the incident such as identification of vehicles and people involved, the extent of injuries, hazardous material, resources on site, site management strategies in effect, and current clearance status. Emergency personnel may also send in-vehicle signing messages to approaching traffic using short range communications.
