发明名称 Traffic control system
摘要 A traffic control system 10 is provided having an illuminating member 42 and a rotating drum 48. The drum 48 is provided with a red reflector 50, a green reflector 52 and a yellow reflector 54 formed on different portions thereof. A control channel 14 is provided for selectively rotating the drum 48 so that each reflector 50, 52 and 54 can be illuminated by the illuminating member 42 thus providing an indication whether a vehicle should stop, go or exercise caution. The traffic control system 10 is also provided with a monitoring channel 16 which monitors the control channel 14 to insure the circuit is operating properly.
