Triple
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).

Solutions
   Solution Description
This solution is used within the U.S. It combines standards associated with US: NTCIP Signal Priority with those for I-F: OMG DDS RPC. The US: NTCIP Signal Priority standards include upper-layer standards required to implement centre-to-field traffic signal control priority communications (e.g., for busses and emergency vehicles). The I-F: OMG DDS RPC standards include lower-layer standards that support secure remote procedure calls between a field device and another field device or a centre over a field communication link
