Traffic Management Center --> Rail Operations Center:
rail crossing advisories
Definitions
rail crossing advisories (Information Flow): Notification of Highway-Rail Intersection equipment failure, intersection blockage, or other condition requiring attention, and maintenance activities at or near highway rail intersections.
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.
Rail Operations Center (Destination Physical Object): 'Rail Operations Center' represents the (usually) centralized control point for a substantial segment of a freight railroad's operations and maintenance activities. It is roughly the railroad equivalent to a highway Traffic Management Center. It is the source and destination of information that can be used to coordinate rail and highway traffic management and maintenance operations. It is also the source and destination for incident, incident response, disaster, or evacuation information that is exchanged with an Emergency Management Center. The use of a single object for multiple sources and destination for information exchange with railroads implies the need for a single, consistent interface between a given railroad's operations and maintenance activities and ITS.

If intercepted by a third party, could be used to embarras the relevant stakeholders, or as contributing information toward target selection (if for example a piece of monitoring equipment was listed as non-functional). | This will trigger maintenance activity, so it must be correct or such activities will not be properly scheduled and resources suboptimally assgned.
