Data Distribution System --> ITS Object:
data query publication

Definitions

data query publication (Information Flow): Data query publication includes those dialogs necessary to satisfy the response portion of a query-response action using the data distribution architecture. The information content varies widely based on available content and the query, but it generally includes information on the state of transportation system operations including traffic and road conditions, advisories, incidents, transit service information, weather information, parking information, and other related data.

Data Distribution System (Source Physical Object): The 'Data Distribution System' collects, processes, and distributes ITS data, connecting data producers with data consumers and facilitating data exchange.

ITS Object (Destination Physical Object): The general 'ITS Object' includes core capabilities common to any class of object.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Rating High High Moderate
Basis This value is derived from the specific flows satisfied by this super-flow. HIGH is set because some flows may require it. If the implementation includes flows with only a MODERATE or LOW confidentiality requirement, then this could be MODERATE or LOW, as appropriate. This value is derived from the specific flows satisfied by this super-flow. HIGH is set because some flows may require it. If the implementation includes flows with only a MODERATE or LOW integrity requirement, then this could be MODERATE or LOW, as appropriate. Query flows need some level of abailability; if the flow is not satisifed the user may be become frustrated and seek a solution other than DDS. Thus MODERATE.
