Question: an approach at a pretimed signalized intersection has a constant...

Question details

An approach at a pretimed signalized intersection has a constant saturation flow rate of 2400 veh/h and is allocated 24 seconds of effective green time in an 80-second signal cycle. If the total approach flow rate is 500 veh/h and 60% of the traffic arrives in the first 24-seconds of red due to a miscalculated offset, calculate the total delay assuming D/D/1 queuing and average delay.

+ Include a sketch of the delay polygon and Comment about the effect of arrival types and offsets and the delay experienced by drivers. (Please include these two solutions as well, its really important)
