wide area broadcast traveler information Quintuple

Bidirectional?: False

wide area broadcast traveler information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'WAID Broadcast Services', and 'Vehicle Traveler Information Reception'. 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 'wide area broadcast traveler information'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Wide Area Information Disseminator' to 'Vehicle OBE'.

Wide Area Information Disseminator (Source Physical Object): The 'Wide Area Information Disseminator' represents the Connected Vehicle center based systems and communications equipment that is used to send messages to equipped vehicles using wide-area wireless communications such as satellite radio, terrestrial FM broadcast subcarrier, or cellular data networks.

WAID Broadcast Services (Source Application Object): "WAID Broadcast Services" provides wide-area digital broadcast of traveler information to transportation users across a region. It collects traveler information of interest to it's clientele (either subscribers or the general public) and distributes the traveler information using broadcast data services that are offered in context with entertainment and other data services.

Vehicle OBE (Destination 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.

Vehicle Traveler Information Reception (Destination Application Object): "Vehicle Traveler Information Reception" provides the capability for drivers to receive general transportation information including traffic and road conditions, incident information, maintenance and construction information, event information, transit information, parking information, weather information, and broadcast alerts.
