For the intersection shown in the plan view imagery below: Lane utilization, design hourly volumes and mean approach speeds

:$1.$ Assuming two phase $(2$ green phases only$)$ control, compute critical lane flows for the two phases. Use the left turn equivalence factor $($e$\_$L$)$ of $1\mathrm{.}6$ even though protected left turn phases are not provided

$.2.$ Compute clearance intervals $($Yellow and Red$)$ for both green phases using the new ITE method, round your computed values up to the next higher second. $($Apply PRT t$=1$s $).$

$3.$ Use Webster's equation to estimate the cycle length. Instead of using the HCM "default" saturation flow of $1900$ vph$,$ assume we have measured the saturation flow value and it is $1800$ vph$.$

$4.$ Estimate green times for the two phases.
