Interface: Operation Green Light - Data Distribution System
Architecture Flow Definitions
data provision (Planned) 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 (Planned) Applicable ITS Standards
Data publication includes those dialogs necessary to satisfy the publication portion of a data distribution architecture. At its core, it provides data, organized by the sender as a one-to-many. This is a super-flow, meaning that it does not define data elements and is inclusive of any flow that is design to use publish-subscribe.
data query (Planned) 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 (Planned) Applicable ITS Standards
Data query publication includes those dialogs necessary to satisfy the retrieval portion of a query-response action using the data distribution architecture. This is a super-flow, meaning that it does not define data elements and is inclusive of any flow that is design to use query-retrieval.
data subscription (Planned) 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.
regional situation data (Planned)
This general flow represents the traffic, environmental, and emissions situation data that is collected from connected vehicles and aggregated, filtered, and distributed to other centers as a regional information product for use in operations, performance monitoring, and analysis.
