Personal Information Device --> METR Discrepancy Handling System:
METR discrepancy report

Definitions

METR discrepancy report (Information Flow): The "METR discrepancy report" information flow enables a METR User Device to alert the METR Discrepancy Handing Center of detected discrepancies (e.g., a conflict among METR rules, a conflict between an METR rule and a physical TCD) by issuing a report (e.g., images, OCR data) that identifies the apparent discrepancy in transport-related rules. The discrepancy will indicate the rule identifier(s), type of discrepancy, and supporting evidence to assist in a further, independent investigation. The discrepancy might be between electronic rules or between electronic and physical rules.

Personal Information Device (Source Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.

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).

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) - Secure Wireless Internet (EU)

Solution Description

This solution is used within Australia and the E.U.. It combines standards associated with (None-Data) with those for I-M: Secure Wireless Internet (EU). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-M: Secure Wireless Internet (EU) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

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.

Basis Will include some artifact indicating the identity of the reporter; while this could be a pseudonym, it could eventually be associated with the reporter. There is no good reason for discrepancy reporters to be observed by anyone outside the METR system. 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. There should be many opportunities to provide discrepancy reports, so there is no pressing need for a requirement above LOW.
