In a coordination plan, what term refers to the number of seconds assigned to each phase at an intersection?

• A. Duration
• B. Split
• C. Cycle
• D. Interval

Answer: (B)

The term that refers to the number of seconds assigned to each phase at an intersection is "split." In traffic signal coordination, the split indicates how time is allocated among the different signal phases throughout the cycle. Each phase of the signal (e.g., green, yellow, red) is assigned a specific duration, and the split helps in managing the timing to ensure smooth traffic flow and minimize congestion. This concept is crucial for signal timing plans, where the goal is often to effectively balance the needs of vehicles and pedestrians while optimizing the overall traffic efficiency. By adjusting the split durations, traffic engineers can enhance intersection performance and address peak hour demands or varying traffic patterns throughout the day.
