Is there a ladder logic program for a 4 junction traffic light?

Yes, a ladder logic program for a 4-junction traffic light can be designed using timers and relays to control the lights at each junction. The program typically includes states for each traffic light (e.g., red, yellow, green) and logic to ensure safe transitions between them. Timers can be used to manage the duration of each light state, while interlocks prevent conflicting signals at adjacent junctions. This ensures smooth and safe traffic flow at the intersection.
