The table shows the traffic flow and saturation flow rate for a four$-$legged intersection. The lost

time per phase is $2\mathrm{.}4$ seconds $.$ Amber's time

is $3$ seconds per phase. Find the cycle length and the green time. Assume a critical volume$-$to$-$capacity

ratio of $0\mathrm{.}85.$ Draw the phasing and timing diagrams, and determine the overall delay and LOS for the intersection.
