Traffic Management Center --> Fleet and Freight 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.

Fleet and Freight Management Center (Destination Physical Object): The 'Fleet and Freight Management Center' provides the capability for commercial drivers and fleet-freight managers to receive real-time routing information and access databases containing vehicle and/or freight equipment locations as well as carrier, vehicle, freight equipment and driver information. The 'Fleet and Freight Management Center' also provides the capability for fleet managers to monitor the safety and security of their commercial vehicle drivers and fleet.

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

Data for Distribution (TBD) - OASIS MQTT

Solution Description

This solution is used within Australia and the U.S.. It combines standards associated with Data for Distribution (TBD) with those for OASIS MQTT. The Data for Distribution (TBD) standards include a placeholder for upper-layer standards necessary to define the data (elements and structures) necessary to complete a solution for the information flow based on data distribution technologies. The data standard will need to include a specific customization for the desired data distribution technology used (e.g., Kafka, DDS, etc.).. 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 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.
