        Connected Vehicle Roadside Equipment to ITS Roadway Equipment: intersection status monitoring
      Flow Description 
        Current signal phase and timing information for all lanes at a signalized intersection.  This flow represents monitoring of communications by a receiver at the intersection to support monitoring for conflicts between actual signal states and RSE communications about those states.

       Solutions 
                      Solution Description 
        This solution is used within the European Union.  It combines standards associated with EU: Signal Control Messages with those for V-X: BTP/GeoNetworking/G5. The EU: Signal Control Messages standards include upper-layer standards required to implement signal control information flows.  The V-X: BTP/GeoNetworking/G5 standards include lower-layer standards that support broadcast, near constant, low latency vehicle-to-vehicle and vehicle-to-infrastructure communications using the ETSI GeoNetworking Bundle over the 5.9GHz spectrum.
