What does "signal cycling" refer to?

"Signal cycling" refers to the sequence in which traffic signals operate through phases. This concept is crucial for managing the flow of vehicular and pedestrian traffic at intersections. The cycling of signals allows for the coordinated changes in traffic lights, which helps to optimize traffic flow and enhance safety by ensuring that vehicles and pedestrians receive appropriate signals at consistent intervals. By understanding this cycling process, signal technicians can effectively manage timing and make adjustments for various traffic conditions, ensuring that signals operate efficiently and safely for all road users.

Other options address related elements of traffic signal management, but they do not specifically define the overarching concept of signal cycling, which emphasizes the order and timing of the signal phases in coordinated traffic control.
