Architecture Flow Definitions

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.

incident information for public  (Existing)  Applicable ITS Standards

Report of current desensitized incident information prepared for public dissemination.

logged vehicle routes  (Planned)  Applicable ITS Standards

Anticipated route information for guided vehicles, special vehicles (e.g., oversize vehicles) or groups of vehicles (e.g., governor's motorcade) that may require changes in traffic control strategy.

road network conditions  (Planned)  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.

traffic control information  (Existing)  Applicable ITS Standards

Represents the flow of traffic control and status information from a TMC to a third party TIC. This is reporting only, not actual control.

traffic images  (Planned)  Applicable ITS Standards

High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images and meta data that describes the images.
