Abstract
An on-board unit (OBU) of a vehicle receives one or more data messages indicative of intersection geometry for an upcoming intersection along a roadway being traversed by the vehicle and traffic control status of a traffic control of the intersection. An outbound direction for the vehicle through the intersection is identified. A first traffic message is sent to preempt the traffic control to allow the vehicle to perform a maneuver to traverse the intersection in the outbound direction. The maneuver is indicated as complete and a second traffic message is sent to discontinue the preempt of the traffic control.
