Traffic Management Center --> Vehicle Operations and Service Center:
traffic images
Definitions
traffic images (Information Flow): 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. Meta data that describes the images is contained in another flow.
Traffic Management Center (Source 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.
Vehicle Operations and Service Center (Destination Physical Object): 'Vehicle Operations and Service Center' (VOSC) represents centers that provide telematics services to vehicles using wide-area (e.g. cellular) communications, including traveler information, emergency services, vehicle diagnostics, over-the-air software updates, vehicle maintenance information and warnings, remote vehicle operation, and provision of service options for these vehicles. See also 'Transportation Information Center' that provides traveler information, trip planning, and routing services and 'Emergency Management Center' that provides call-taking and emergency response services that may also be implemented by a VOSC.

| 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). |

| Confidentiality | Integrity | Availability | ||
| Rating | Low | Moderate | Moderate | |
| Basis | Traffic image data is generally intended for public consumption, and in any event is already video captured in the public arena, so this must be LOW. | While accuracy of this data is important for decision making purposes, applications should be able to cfunction without it. Thus MODERATE generally. | While availability of imagery is useful for decision making purposes, applications should be able to cfunction without it.
