Other Traffic Management Centers --> Traffic Management Center:
traffic image meta data
This triple is bi-directional. See also
Traffic Management Center --> Other Traffic Management Centers: traffic image meta data
Definitions
traffic image meta data (Information Flow): Meta data that describes traffic images. Traffic images (video) are in another flow.
Other Traffic Management Centers (Source Physical Object): Representing another Traffic Management Center, 'Other Traffic Management Centers' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) traffic management functions. It enables traffic management activities to be coordinated across different jurisdictional areas.
Traffic Management Center (Destination Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.

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). |
