UtmcXml is an XML representation of the Urban Traffic Management Control model that can be used to exchange data objects between UTMC databases and other services.

.

This subschema describes the Freeflow Intervention Data Object . An Intervention object sends information from an Intelligent Decision Support Subsystem to UTMC database recommending an change to the system state order to ibe performed by a network operator or other agent.

It may include one or more component elements,

  • A definition including textual description.
  • Preconditions that should still be in effect when the intervention is executed (to be developed further)
  • Commands to be executed to make the intervention.
  • References to predictions that the intervention will result in
