Definitions

road network conditions (Information Flow): Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.

Traffic Management Center (Source 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.

Commercial Vehicle Administration Center (Destination Physical Object): The 'Commercial Vehicle Administration Center' performs administrative functions supporting credentials, tax, and safety regulations associated with commercial vehicles. It issues credentials, collects fees and taxes, and supports enforcement of credential requirements. It communicates with motor carriers to process credentials applications and collect fuel taxes, weight/distance taxes, and other taxes and fees associated with commercial vehicle operations. It also receives applications for, and issues special Oversize/Overweight and HAZMAT permits in coordination with cognizant authorities. It coordinates with other Commercial Vehicle Administration Centers (in other states/regions) to support nationwide access to credentials and safety information for administration and enforcement functions. It communicates with field equipment to enable credential checking and safety information collection at the roadside. It makes safety information available to qualified stakeholders to identify carriers and drivers that operate unsafely.

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

EU: DATEX - DATEX Messaging

Solution Description

This solution is used within the E.U.. It combines standards associated with EU: DATEX with those for C-C: DATEX Messaging. The EU: DATEX standards include upper-layer standards required to exchange and share data and information in the field of traffic and travel. The C-C: DATEX Messaging standards include lower-layer standards that support partially secure communications between two centers as commonly used in Europe.

ITS Application Entity Bundle: DATEX			Click gap icons for more info.
Mgmt Bundle: SNMPv3 MIB W3C WSDL 1.1	Facilities No Standard Needed	Security IETF RFC 8446
	TransNet IP Alternatives IETF RFC 9293
	Access Internet Subnet Alternatives

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	Moderate	Moderate
Basis	No harm should come from seeing this data, as it is eventually intended for public consumption.	While accuracy of this data is important for decision making purposes, applications should be able to corroborate the data in many instances. Thus MODERATE generally.	condition info should be timely and readily available so that TMCs are aware of current traffic info, conditions, restrictions, etc. but should not have severe/catastrophic consequences if not
