Design a PLC ladder logic program to control a stop light. The
program should have 3 outputs: RED, YELLOW, and GREEN. The ladder
logic should illuminate green for 60 seconds, then yellow for 10
seconds, then red for 60 seconds. The system should also have two
sensor inputs: THROUGH_TRAFFIC and CROSS_TRAFFIC which detect when
there is through traffic and cross traffic present. If through
traffic is detected, and no cross traffic is detected, the system
should maintain a green light...
