So today we have come back to enjoy programming such a critical and large project by using ladder logic programming and for sure will apply the code and the logic we write into the simulator to check its correctness. The brain that handles the complicated logic behind the traffic light control system is a PLC and one programmer like you guys has written its logic.
But nowadays, most traffic lights are controlled by automatic control systems. Controlling traffic signs was managed by people which was very problematic and headache on travelers and the officers as well. The traffic light is one of the most important applications we see everyday everywhere we go back and forth. Figure 7: The sad outcomes of proceeding with out controlling the two ways
