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 'Personal 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 'Personal Information Device'.

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.

Personal Information Device (Destination Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with connected vehicle on-board equipment.

Personal Traveler Information Reception (Destination Application Object): "Personal Traveler Information Reception" receives formatted traffic advisories, road conditions, transit information, broadcast alerts, and other general traveler information broadcasts and presents the information to the traveler. The traveler information broadcasts are received by personal devices including personal computers and personal portable devices such as smart phones.
