Connected Vehicle Roadside Equipment to ITS Roadway Equipment: signal priority service request
Flow Description
A service request for vehicle priority issued to a traffic signal controller that results in green extension or other accommodation for the priority vehicle, within the current signal timing plan. The request includes the priority level, the desired time and duration of service, and the intended travel path through the intersection. This flow also allows the RSE to cancel a previously issued request for priority.

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: SNMPv3. 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: SNMPv3 standards include lower-layer standards that support secure centre-to-field and field-to-field communications using simple network management protocol (SNMPv3); implementations are strongly encouraged to use the TLS for SNMP security option for this solution to ensure adeqaute security.
