What is a single sequence of displays that gives each movement at the intersection a chance to proceed through the intersection on a green indication?

The correct choice is based on the concept of traffic signal operation. A cycle refers to one complete round of all the traffic signal indications that allows each movement at an intersection—such as vehicles, bicycles, and pedestrians—to receive a green indication in a systematic order. This ensures that different movements are allocated time to safely proceed through the intersection.

Understanding this term is crucial in traffic signal management, as it relates directly to the timing and sequence of signals displayed at an intersection. Each cycle is designed to optimize traffic flow and enhance safety for all road users by minimizing conflicts and ensuring that all movements have an opportunity to proceed.

While the other terms—sequence, interval, and phase—are related to traffic signal operations, they do not represent the complete concept of the entire cycle of displays. A sequence refers more to the order in which signals change, an interval pertains to the time allocated for specific phases, and a phase denotes a specific movement of traffic (e.g., northbound vehicles moving on green). In contrast, a cycle encompasses all phases and sequences, making it the best choice.
