1.1.5: Exchange Data with Other Traffic Centers

This process shall exchange data with the Other Traffic Management terminator. This represents the exchange of data between peer Manage Traffic functions (e.g. between peer Traffic Management Centers (TMCs)). The other TMC can be adjacent geographically, under control of a different jurisdiction, or part of a more complex hierarchy. The exchange of data may be triggered by a request to (or from) the Other Traffic Management terminator or the exchange of data may be initiated without a specific request. This data shall include both traffic information and traffic control data. Some examples of these exchanges are: traffic control preemption for vehicle routes which pass through the local network but have a destination in an area served by another remote TMC; data about an incident that has an impact on the traffic conditions in the network served by a remote TMC; control data for the Manage Traffic function to control video cameras or environmental sensors under the jurisdiction of another traffic management organization; or requests for control of the other center's field equipment. The data received from remote TMCs could be used to vary the current traffic control strategy to give signal preemption to emergency vehicles or enable the passage of commercial vehicles with unusual loads, or as input to the local traffic predictive model estimation process.

This process is associated with the Traffic Management Center physical object.

This process is associated with the following application objects:

• TMC Environmental Monitoring
• TMC Evacuation Support
• TMC Incident Dispatch Coordination/Communication
• TMC Regional Traffic Management
• TMC Signal Control
• TMC Traffic Surveillance
