        Connected Vehicle Roadside Equipment to ITS Roadway Equipment: signal preemption request
      Flow Description 
        Direct request for preemption to a traffic signal controller that results in preemption of the current control plan and grants right-of-way to the requesting vehicle.  This flow identifies the required phase and timing of the preemption.  This flow may also cancel the preemption request (e.g., when the requesting vehicle clears the intersection).

                Solution Description 
        This solution is used within the Australia.  It combines standards associated with (None-Data) with those for I-F: AU IFCP. The (None-Data) standards include an unspecified set of standards at the upper layers.  The I-F: AU IFCP standards include lower-layer placeholder for an Australian solution identified for development. This may end up being I-F: SNMPv3, but it is currently undefined and just used as a placeholder.
