Triple
Transit Vehicle OBE to Connected Vehicle Roadside Equipment: local signal priority request
Flow Description
Request from a vehicle to a signalized intersection for priority at that intersection. This flow also allows the vehicle to cancel a priority request (for example, when the vehicle clears the intersection).
Solutions
US: SAE Signal Preemption - Local Unicast Wireless (US)

EU: Signal Control Messages - Local Broadcast Wireless (AU/EU)
Solution Description
This solution is used within the U.S.. It combines standards associated with US: SAE Signal Preemption with those for V-X: Local Unicast Wireless (US). The US: SAE Signal Preemption standards include upper-layer standards required to implement signal preemption and priority information flows. The V-X: Local Unicast Wireless (US) standards include lower-layer standards that support local-area unicast wireless solutions, such as DSRC technologies, LTE, etc.
