– 2.5 seconds for the first 10 seconds

– 2 seconds for the time period of 44 ‐ 50 seconds, and for thetime period of 130 ‐ 166 seconds

– No vehicle was observed in‐between of the above timeperiods.

– Collected data also show that the cycle length is 200 secondswith 140 seconds for the effective red time and 60 seconds for theeffective green time.
