Abstract
A system for alerting school children that a school bus is moving toward a nearby bus stop, thus prompting the children to leave their residences to reach the bus stop at or before the bus arrives at the stop. The system includes a radio transmitter on the bus and a radio receiver in each home along the bus route. Each receiver has a first warning light that begins to emit a signal when the school bus is a relatively great distance away from the home, and a second sound-emitting speaker that begins to emit an audible signal when the school bus is a relatively short distance away from the home, e.g. one quarter mile.
