Traffic Management Center --> Archived Data System:
performance metrics

Definitions

performance metrics (Information Flow): Data that indicates how well the transportation system is performing. Performance metrics are tracked over time to monitor progress towards operations objectives and identify needs and deficiencies to be addressed.

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.

Archived Data System (Destination Physical Object): The 'Archived Data System' collects, archives, manages, and distributes data generated from ITS sources for use in transportation administration, policy evaluation, safety, planning, performance monitoring, program assessment, operations, and research applications. The data received is formatted and tagged with attributes that define the data source, conditions under which it was collected, data transformations, and other information (i.e. meta data) necessary to interpret the data. The archive can fuse ITS generated data with data from non-ITS sources and other archives to generate information products utilizing data from multiple functional areas, modes, and jurisdictions. The archive prepares data products that can serve as inputs to federal, state, and local data reporting systems. The 'Archived Data System' may reside within an operational center and provide focused access to a particular agency's data archives. Alternatively, it may operate as a distinct center that collects data from multiple agencies and sources and provides a general data warehouse service.

    InteroperabilityDescription
    RegionalInteroperability 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 Contains information characterizing the performance of some aspect(s) of the transportation system; not typically competetive, will include no PII. Might in some circumstances be slightly sensitive, but there's no clear case where observation of this information by a third party would cause significant impact. Decisions may be made regarding this information; if the information were incorrect, suboptimal decisions may be made. Much depends on how integrated the performance information is to traffic management decision-making. If integral, this could be MODERATE. Generally though, the transportation system should be able to function reasonably with occasional outages.
