METR System --> Other METR Systems:
consolidated discrepancy report

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

Definitions

consolidated discrepancy report (Information Flow): This flow allows the METR Discrepancy Handling Center to send consolidated discrepancy reports to the intended destination. The consolidated reports are sent when conditions, as defined by local policies, are met (e.g., a sufficient number of reports have been received). The destination might be another METR Discrepancy Handing Center (e.g., an OEM sending data to a governmental handling system) but eventually, the consolidated reports are sent to the relevant METR Regulation Center.

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

METR: Discrepancy Reporting Requirements - OASIS MQTT

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with METR: Discrepancy Reporting Requirements with those for OASIS MQTT. The METR: Discrepancy Reporting Requirements standards include upper-layer standards required to exchange traffic regulation discrepancies with a discrepancy handling center. The OASIS MQTT standards include lower-layer standards that support data distribution of specific types of data.

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.
