broadcast traveler information Quintuple

Bidirectional?: False

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

Transportation Information Center (Source Physical Object): The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.

TIC Traveler Information Broadcast (Source Application Object): "TIC Traveler Information Broadcast" disseminates traveler information including traffic and road conditions, incident information, maintenance and construction information, event information, transit information, parking information, and weather information. The same information is broadcast to all equipped traveler interface systems and vehicles.

Wide Area Information Disseminator (Destination 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 (Destination 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.
