Abstract

A system and method whereby school children waiting for the arrival of a school bus are notified of impending arrival of the bus by means of a radio transmitted signal which activates a visual or audio alarm located in their respective residences. A radio frequency transmitter is placed in each school bus, with the transmission frequency selected to correspond to a particular bus route. A radio frequency receiver is placed within a plurality of selected residences along a bus route and tuned to receive the frequency corresponding to that transmitted by the bus following the route followed by the bus which is to stop and pick up children at that residence. When the receiver receives the transmitted signal, an audible or visual alarm is activated thereby notifying the occupants of the residence of the impending arrival of the bus. The sensitivity of each receiver to the transmitted signal is adjustable so that the receiver will not activate its alarm until the bus is a certain distance away, thereby reducing to a minimum the amount of time the children must wait at the bus stop, yet giving them sufficient time to be aware of the approach of the bus. The notification system is intended for use in both urban and rural areas wherein the school buses following different routes will be equipped with transmitters of respective different frequencies, and the various groups of residences are equipped with receivers sensitive to the same respective frequencies, depending on the bus which the children living in the residences are to take.
