Traffic Management Center --> Parking Management Center:
parking traffic information
Definitions
parking traffic information (Information Flow): Instructions for operation of local parking facilities to support regional traffic management objectives (e.g., which parking lot exits to use). Also, includes inputs from traffic sensors to monitor parking queues and support more effective management of parking entrances and exits.
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.
Parking Management Center (Destination Physical Object): The 'Parking Management Center' manages one or more parking lots by providing configuration and control of field infrastructure, user account management and interfaces with financial systems to manage payment. This p-object takes the back office portion of the Parking Management System's functionality as it was defined in ARC-IT 8.3 and prior.

| 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). |

| Rating | Low | Moderate | Low | |
| Basis | Provides some indication of regional traffic management strategies, which might be useful to an attacker, but that is far from obvious. Marked LOW unless a use case for an attack based on this information seems likely. | If this flow were corrupted or modified then parking systems might not be able to cope with increased traffic as a result of regional management strategies. The impact will be inconvenience on the part of travelers, potentially many, but not a catastrophic event. | Probably does not need to be updated often. | |
