Practice question

What components make up the phases assigned to a major street movement?

  1. Split, cycle length, and minimum green
  2. Green time, yellow time, and red time
  3. Cycle length, split, and passage time
  4. Flow rate, volume count, and timing purpose

Answer: C — Cycle length, split, and passage time

The correct components that make up the phases assigned to a major street movement are best represented by cycle length, split, and passage time. Cycle length refers to the total time allocated for one complete sequence of signal phases. It encompasses the green, yellow, and red phases for all movements at the intersection. This is crucial for understanding how traffic flow is managed over time. The split signifies how the total cycle time is divided among various movements at the intersection. For major street movements, the split focuses on how much time is allocated for the major street to allow for vehicle passage, making it an essential factor in traffic signal timing. Passage time is important as it defines the duration during which vehicles can effectively pass through the intersection during the green phase. This directly influences the efficiency of traffic flow and ensures that vehicles have adequate time to clear the intersection safely. In contrast, the other choices don't comprehensively encapsulate the phases assigned to a major street movement. While components like green time, yellow time, and red time contribute to the overall operation of traffic signals, focusing solely on those elements overlooks the broader considerations of cycle length and split. Similarly, flow rate, volume count, and timing purpose do not directly tie into the fundamental components that define how major street movements
