ABSTRACT:
The invention is a versatile school bus traffic control system. When power is first applied, or the RESET pushbutton is pushed, it is set to its quiescent state. Pushing the MODE ADVANCE pushbutton switch will advance to the next state: flashing alternating yellow traffic control lights. The next push of MODE ADVANCE will advance the system to: flash traffic control lights, one side red and the other side yellow, next, the complementing red and yellow. This is repeated for approximately three seconds, next, automatically advancing to only alternating red traffic control lights flash, until MODE ADVANCE is again pushed. The invention then returns to quiescence. Optionally, the invention will reset, and or not respond to MODE ADVANCE if the school bus is in motion.
