Abstract
A bus lane prioritization system and method uses an approach magnetometer to detect a bus or other vehicle in a bus lane approaching an intersection, and an island exit magnetometer to detect when the vehicle has cleared the intersection. When the vehicle is approaching the intersection, the system signals a traffic light controller to control at least one traffic light to allow the vehicle in the bus lane to traverse the intersection without delay or with minimal delay, thereby prioritizing the bus lane. An optional crossing gate may also be used to prevent traffic from a perpendicular roadway from entering the intersection. When the vehicle clears the intersection, the system informs the traffic light controller that it is no longer necessary to configure the at least one traffic light to prioritize the bus lane, and optionally controls the crossing gate in a manner synchronized to the at least one traffic light.
