Data Distribution System --> Personal Information Device:
data publication
Definitions
data publication (Information Flow): Data publication includes those dialogs necessary to satisfy the publication portion of a data distribution architecture. The information content varies widely based on available content and the subscription, 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.
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 vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.

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.

MODERATE is set because some flows may require it. If the implementation includes flows with only a LOW availability requirement, then this could be LOW. HIGH is not considered; any flow requiring HIGH availability will not use DDS. |
