Practice question

What is the purpose of 'gap reduction' (variable initial) in actuated controllers?

To reduce the minimum green time during low-volume periods
To progressively shorten the passage time as a phase exceeds its minimum green, allowing earlier gap-out
To eliminate gaps between vehicles in a platoon
To reduce the yellow change interval during light traffic

Answer: B — To progressively shorten the passage time as a phase exceeds its minimum green, allowing earlier gap-out
