As we have mentioned earlier we are going to work the project into couple of milestones. Our task is to control the timing of lighting each indicator to achieve the whole process. Each lamp has assigned to one output as you can see guys in the image. Each traffic light side has three indicators RED, green, and Ampere to represent the stop, ready-to-cross, and about-to-change that tells the car drivers and pedestrians when to stop and what time they can continue crossing. So without any further delay let’s jump into our project’s exercises.įigure 1: the cross traffic light project Project descriptionĪs you can see in figure 2, there are two faces of three traffic lights, one for each side way to control the cross traffic light.

The complete project will be divided into two tasks to simplify the project and each task will be an exercise for you guys to do. We need to go through the logic and requirements and then list these alongside with the restrictions for realizing the safety which is very critical and crucial right here for saving people and vehicles traveling in each way in the cross traffic light. Problem we try to solveįirst of all, the scene we captured below by figure 1 shows two ways to cross a traffic signal, the biggest and most complicated traffic sign you might see anywhere you go. 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
