Why do operating times and timings on green light cycles differ between ramp signal locations?
Because traffic conditions and demands are different on each on-ramp, the operating times and the green light timings on each set of ramp signals will be slightly different and customised to manage those exact conditions. Some areas experience high demand at different times of the day to others, some have longer peak times, and most differ in the volume of traffic travelling across the ramp during peak times. The ramp signalling system is designed to monitor and adjust to these traffic conditions to free up traffic.
