Abstract
Approaches are disclosed for timing the submission of transit signal priority (TSP) requests. A phase selector receives TSP information of a vehicle at a current time, and the phase selector determines an estimated time of arrival (ETA) of the vehicle at an intersection having a traffic signal controlled by an intersection controller. The phase selector determines the arrival phase of the traffic signal at the ETA, along with a phase-relative arrival time of the ETA. The phase selector determines a time to issue the TSP request based on the phase-relative arrival time, and issues the TSP request to the intersection controller at the determined time.
