Traffic Regulatory Authority Center --> Traffic Management Center:
traffic-related regulations

Definitions

traffic-related regulations (Information Flow): 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. The flow includes the regulations and the associated locations, effective date and time periods, and applicable vehicle classes. This flow supports bulk transfer of regulations, rules, statutes, and related attributes between back office systems.

Traffic Regulatory Authority Center (Source Physical Object): The 'Traffic Regulatory Authority Center' is the authoritative source for 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 center may represent multiple authorities that operate at local, regional, state, and national levels and represents organizations that establish, manage, and enact the traffic code.

Traffic Management Center (Destination Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.

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) - OMG DDS

Solution Description

This solution is used within the U.S.. It combines standards associated with (None-Data) with those for OMG DDS. The (None-Data) standards include an unspecified set of standards at the upper layers. The OMG DDS standards include lower-layer standards that support secure data sharing and command operations between remote devices.

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).

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Low High Moderate
Basis Regulations should be publicly accessible, so observation of this flow gains no information that could not be obtained legitimately. Regulations may be used to guide operations, particularly for automated vehicles. As such, inaccurate regulations imply the vehicle operator (human or otherwise) may inadvertently violate regulations, possibly endangering the safety of others expecting the operator or vehicle to follow the rules of the road. Regulations will be used to guide the operator, which may be an autonomous vehicle. As such the regulations need to be kept up to date to avoid conflict with regulations, penalties or of course safety of life. Availability is not considered HIGH as it is unlikely that such regulations that affect safety would change very often. In environments where it is envisioned that safety-impacting regulations change quickly, HIGH would be justified.
