Connected Vehicle Roadside Equipment to Transit Vehicle OBE: intersection status
Flow Description
Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.

   Solution Description
This solution is used within the U.S.. It combines standards associated with US: SAE Signal Control Messages with those for V-X: WAVE WSMP. The US: SAE Signal Control Messages standards include upper-layer standards required to implement signal control information flows. The V-X: WAVE WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.
