question 3: a signalized intersection approach operates at an effective ratio of 1.05 for a peak 30- minute period each evening. if the approach has a g/c ratio of 0.6 and the cycle length is 75 seconds then assuming saturation headway as 2.8 sec/veh: a) what is the average control delay during the entire 30-minute (0.5 points). b) what is the average control delay during the first 5 minutes (0.5 points).
