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

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

Definitions

discrepancy report details (Information Flow): While investigating a consolidated discrepancy report, a translator agent might wish to see additional details (e.g., specifics about the time of each report, images included in the report). If so, they can make a request and obtain the discrepancy report details flow. Additionally, discrepancy report details can be transferred between METR Discrepancy Handling Centers.

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

METR System (Destination 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.

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 - Secure Internet (ITS)

Solution Description

This solution is used within Canada, the E.U. and the U.S.. It combines standards associated with METR: Discrepancy Reporting Requirements with those for I-I: Secure Internet (ITS). The METR: Discrepancy Reporting Requirements standards include upper-layer standards required to exchange traffic regulation discrepancies with a discrepancy handling center. The I-I: Secure Internet (ITS) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

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.
