Architecture Flow Definitions
archive requests (Existing) Applicable ITS Standards
A request to a data source for information on available data (i.e., "catalog") or a request that defines the data to be archived. The request can be a general subscription intended to initiate a continuous or regular data stream or a specific request intended to initiate a one–time response from the recipient.
archive status (Existing) Applicable ITS Standards
Notification that data provided to an archive contains erroneous, missing, or suspicious data or verification that the data provided appears valid. If an error has been detected, the offending data and the nature of the potential problem are identified.
center archive data (Existing) Applicable ITS Standards
Information describing center operations and measures that reflect the impact of these operations on the transportation system. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.
commercial vehicle trip information (Planned) Applicable ITS Standards
Information about vehicle trips including load information, location, speed, and routing. The information would be sanitized for distribution outside of the commercial vehicle company.
data provision (Existing) Applicable ITS Standards
Data provision provides the source material for a publish–subscribe or query–retrieval data distribution scheme. This is the 1 of the 1:N data distribution architecture. This flow is a super–flow; it does not define data elements but is inclusive of any flow implemented using publish–subscribe or query–retrieval methods.
data publication (Existing) Applicable ITS Standards
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 query (Existing) Applicable ITS Standards
Data query includes those dialogs necessary to determine what data is available for and also submit a query for near–term response.
data query publication (Existing) Applicable ITS Standards
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 subscription (Existing) Applicable ITS Standards
Data subscription includes those dialogs necessary to determine what data is available for subscription/query, and also the dialogs necessary to create or modify data subscriptions/queries.
freight traveler information preferences (Planned) Applicable ITS Standards
Traveler information preferences from fleet and freight management systems or commercial vehicle drivers including: area covered by fleet/driver, types of freight managed (including special restrictions), preferred routes, other travel preferences pertaining to trip costs or tolls.
freight-specific traveler information (Planned) Applicable ITS Standards
Traveler information customized for freight users to indicate truck routes, permit information, truck stops, inspection stations, steep grades, high–profile vehicle advisories, etc. Information provided includes freight–related road and weather conditions, parking information, and route plans.
incident information for public (Existing) Applicable ITS Standards
Report of current desensitized incident information prepared for public dissemination.
railroad advisories (Existing) Applicable ITS Standards
Real–time notification of railway–related incident or advisory.
railroad schedules (Existing) Applicable ITS Standards
Train schedules, maintenance schedules, and other information from the railroad that supports forecast of HRI closures.
road network conditions (Existing) Applicable ITS Standards
Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.
