Abstract
A wireless head for a traffic preemption system. Implementations may include one or more optical receivers adapted to identify an optical signal transmitted by an optical transmitter included in a vehicle preemption unit mounted to a vehicle and one or more head radio transceivers adapted to identify a radio signal transmitted by a vehicle radio transceiver included in the vehicle preemption unit. A head radio frequency (RF) modem may also be included adapted to transmit one or more radio signals to an intersection RF modem. The head may be mounted to a traffic support fixture. The one or more optical receivers, one or more head radio transceivers, and the head RF modem may all be operably coupled together within the wireless head. The intersection preemption unit may be adapted to change a traffic light in favor of the vehicle to which the vehicle preemption unit is mounted.
