METR System --> Other METR Systems:
system-generated discrepancy report

This triple is bi-directional. See also Other METR Systems --> METR System: system-generated discrepancy report

Definitions

system-generated discrepancy report (Information Flow): METR Regulation Centers can learn of discrepancies from METR Distribution Centers or other regulation centers that identify conflicts during their rule verification processes. The system-generated discrepancy report identifies the specific elements of METR information that caused the verification error, including the METR information identifier and the specific issue that caused the problem.

METR System (Source Physical Object): The 'METR System' creates and maintains electronic versions of traffic rules, regulations, ordinances and statutes that have official status and must be understood by all motor vehicle operators and intelligent vehicles that operate at higher automation levels. This system represents multiple authorities that operate at local, regional, state, and national levels and represents organizations that establish, manage, and enact the traffic code. Each electronic rule is approved, signed, and traceable to a specific rule-maker. Rules are independently verified. Any identified or reported rule discrepancies are analyzed, investigated, and addressed.

Other METR Systems (Destination Physical Object): The 'Other METR System' represents...

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - OASIS AMQP

Solution Description

This solution is used within the E.U. and the U.S.. It combines standards associated with (None-Data) with those for OASIS AMQP. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS AMQP standards include lower-layer standards that support data distribution of specific types of data.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

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).

Basis Discrepancy-handling flows may contain a significant amount of discrepancy reporting information, which could imply behavior in the field, actions of rules-agents and other activities that could be leveraged by bad actors. Information contained in this flow will be used to assess the accuracy of existing rules; this will require some process that strips out incorrect reports, but the number of incorrect reports should be minimized to reduce undue processing.` Backoffice discrepancy handling flows should be basically reliable, else the discrepancy handling system will have difficulty functioning, which in turn could lead to negative safety or other impacts in the field.
