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.

Claim (Index 1):
A system for prioritizing bus lane traffic comprising:\n an approach magnetometer positioned in a bus lane at a first distance in front of an entrance to an intersection, the first distance being sufficient to provide an amount of time prior to arrival at the intersection of a vehicle traveling at an expected rate of speed; an exit island magnetometer positioned in the bus lane near an exit of the intersection; a base station configured for communication with the approach magnetometer and the exit island magnetometer; a system controller connected to the base station and connectable to a traffic signal controller; wherein the system controller is configured to\n determine a presence of the vehicle in the bus lane based on a signal from the approach magnetometer, wherein the signal from the approach magnetometer is created by a presence of a metallic object, wherein the approach magnetometer does not send a signal for the presence smaller metallic objects; \n in response to determining the presence of the vehicle based on the signal from the approach magnetometer, send a first signal to the traffic signal controller to cause the traffic signal controller to set at least one first traffic signal to a state that allows the vehicle to traverse the intersection; \n determine that the vehicle has cleared the intersection based on a signal from the exit island magnetometer; and \n in response to determining that the vehicle has cleared the intersection, send a second signal to the traffic controller to inform the traffic signal controller that it no longer needs to set the at least one first traffic signal to a state that allows the vehicle to pass through the intersection.
