Multi-Access Edge Computing --> Traffic Management Center:
intersection management application status
This flow may also be implemented by
Connected Vehicle Roadside Equipment --> Traffic Management Center: intersection management application status Definitions
intersection management application status (Information Flow): Infrastructure application status including current operational state and status of the field device and a log of operations.
Multi-Access Edge Computing (Source Physical Object): 'Multi-Access Edge Computing' ((MEC) previously known as mobile edge computing) represents computing devices that operate and are managed like a cloud server, but are deployed at the edge of a network (typically a cellular network, but it could be any network). While not in strict proximity to the transportation network, these systems do benefit from vastly decreased distances to the roadway compared to central systems, and so can provide lower latency than strictly backoffice systems
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 |
|---|---|
| Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

| Basis | This information could be of interest to a malicious individual who is attempting to determine the best way to accomplish a crime. As such it would be best to not make it easily accessible. May be LOW in some cases. | If this is compromised, it could send unnecessary maintenance workers, or worse report plausible data that is erroneous. From THEA: should be able to cope with some bad information on the status and record of alerts/warnings; aggregate info; however could cause appearance of excessive traffic violations or unnecessary maintenance caused if data is compromised (operational state, status, log); should not affect the application functionality | Incident status information should be presented in timely fashion as large scale mobility and safety issues are related. There are other mechanisms for reporting this information however, thus MODERATE. From THEA: Only limited adverse effect of info is not timely/readily available | |
