What term describes the set of phase allocations for a given timing sequence equaling the sum of green, pedestrian clearance, yellow, and all-red times?

What term describes the set of phase allocations for a given timing sequence equaling the sum of green, pedestrian clearance, yellow, and all-red times?

• A. Cycle
• B. Split
• C. Phase
• D. Offset

Answer: (B)

Distributing one fixed cycle length among the various movements is what the split describes. Each phase has a duration that includes green time plus any pedestrian clearance, yellow time, and the all-red interval before the next phase. When you list these allocations for every phase in the timing sequence, their total adds up to the cycle length. This distribution—how much of the cycle is given to each phase—is called the split. The cycle is the total time for the whole sequence; a phase is a single movement’s active interval; an offset is the time shift between signals. So the term that fits is split.
