METR Discrepancy Handling System --> Other METR Discrepancy Handling Systems: discrepancy suppression information
Definitions
discrepancy suppression information (Information Flow): Once a METR Regulation Center has been alerted to a discrepancy, it may wish to suppress further notices in one of two ways. If it still wants vehicles to gather data but for that data not to be submitted except on request, it can use discrepancy suppression info flow to prevent METR Discrepancy Handling Centers from issuing consolidated discrepancy reports (but the newly gathered information is still available through the detailed flow). Alternatively, the METR Regulation Center can revise the associated rule meta-data to inform vehicles that a discrepancy with the rule is already known and that discrepancy reports should not be provided for the rule. This mechanism uses the centralized and localized rule distribution services. Furthermore, the METR Regulation Center may wish to inform other METR Discrepancy Handling Centers to correspondingly suppress further notices of those suppressed discrepancies.
Other METR Discrepancy Handling Systems (Source Physical Object): Depending on deployments scenarios, a discrepancy report might be passed among multiple levels of Discrepancy Handling Systems. For example, a vehicle might be configured to report all its detected discrepancies to an OEM-operated Discrepancy Handling Center. This allows the OEM to become aware of potential problems with its discrepancy detection logic.
Once established thresholds are met, the OEM-operated Discrepancy Handling System might notify a Discrepancy Handling Center operated by a jurisdictional entity. The jurisdictional Discrepancy Handling System can then determine when the METR Regulation System is notified of the reported discrepancies.
METR Discrepancy Handling System (Destination Physical Object): The 'METR Discrepancy Handling System' receives reports of discrepancies in rules from METR User Systems. It will perform a numerical analysis of discrepancy count vs. time for any given rule, and when warranted, report to the METR Regulation Center those rules with sufficient discrepancy reports to justify further investigation. It is identified as a separate center to provide a level of anonymity for the user that reports the issue. The METR Discrepancy Handling Center may register its availability as a service, and its associated cyber location information, with the Object Registration and Discovery System (ORDS).

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. |
