Question: An isolated pretimed signalized intersection has an approach with a saturation flow rate of 1 9 0 0 veh / h . For this approach,

An isolated pretimed signalized intersection has an approach with a saturation flow rate of
1900 veh/h. For this approach, the displayed red time is 58 seconds, the displayed yellow
time is 3 seconds, the all-red time is 2 seconds, the effective green time is 28 seconds, and
the total lost time is 4s? timing stage. Determine the effective red time and cycle length
respectively when the approach flow rate is 550 veh/h?
