Traffic Management Center --> Other Traffic Management Centers:
road network conditions

This triple is bi-directional. See also Other Traffic Management Centers --> Traffic Management Center: road network conditions

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.

Other Traffic Management Centers (Destination Physical Object): Representing another Traffic Management Center, 'Other Traffic Management Centers' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) traffic management functions. It enables traffic management activities to be coordinated across different jurisdictional areas.

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) - OASIS MQTT

Solution Description

This solution is used within Australia, Canada and the U.S.. It combines standards associated with (None-Data) with those for OASIS MQTT. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS MQTT standards include lower-layer standards that support data distribution of specific types of data.

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 encrypted; but no harm should come from seeing this data info needs to be accurate and should not be tampered but should be able to cope with some bad data; should be able to confirm conditions by other mechanisms 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
