Abstract
A system for alerting passengers, particularly school children, that the particular bus they are to board is approaching. The passengers have a receiver which senses the particular signal transmitted by the approaching bus. The passengers listen for and/or watch for a visual indication that the bus is now at the location on its route where preparations should be made for boarding. The bus carries a transmitter which sends out a specific signal identifying that bus. The signal is derived from data which was entered into a signal generator in the transmitter relating to the particular school district, the route to be traveled by the bus, and the number of the bus. Each residence where the school children are waiting has a receiver which will activate an indicating device only when the specific bus identification signal is received.
