Calculate the minimum cycle length and the optimal cycle length for the given traffic volumes. Assume $4$ timing stages with lost time is $4$ seconds per timing stage, $.$ Calculate the effective green time for each of $4$ timing stages using the optimal cycle length. Use a reference sum $($RS$)$ of $1530,$ situation flow rates of $1750$ for left turns, $1800$ for single thru$/$right lanes, and $3400$ for thru and thru$/$right lanes.
