Abstract: A warning system comprising an advanced preemption system is provided to provide warning of an additional advanced preemption time directly from a wayside inspector to a city traffic controller to turn one or more traffic lights red on a route intersecting with the railroad crossing. The advanced preemption system includes a first set of wireless magnetometers to be installed on a railway track of the railroad crossing on a first side of the railroad crossing. The first set of wireless magnetometers to be located at an advanced preemption crossing start activation point that is being at a distance before an existing crossing start activation point of the railroad crossing to provide the warning of the additional advanced preemption time.

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.

Abstract: Systems and methods for detecting train direction and route along a railroad track. The systems and methods use wireless train presence detection sensors such as e.g., magnetometer sensors to detect the presence of the train, and its direction and route along the track.
