transportation weather situation sharing Quintuple

Bidirectional?: True

transportation weather situation sharing (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'TIC Road Weather Advisories and Warnings' application object and the 'Surface Transportation Weather Service' physical object. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Surface Transportation Weather Service (Source Physical Object): The 'Surface Transportation Weather Service' represents the providers of value-added sector-specific meteorological services. These providers utilize National Weather Service data and predictions (including the qualified environmental data from the Clarus system), road condition information and local environmental data provided by traffic management or maintenance organizations, and their own models to provide surface transportation related weather observations and forecasts including pavement temperature and conditions.

Transportation Information Center (Destination 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 Road Weather Advisories and Warnings (Destination Application Object): "TIC Road Weather Advisories and Warnings" collects, aggregates, and processes environmental situation data (aka environmental probe data) from connected vehicles. Environmental situation data may be collected through direct wide area wireless communications with vehicles or through short range communications equipment at the roadside. Aggregated environmental conditions information are distributed to other centers that use the information to support transportation operations and traveler information services.
