$1.$ A one$-$way intersection approach has the following characteristics:

$-65$ seconds of effective green in a $120-$second cycle

$-$ Four $9-$ft lanes $($one exclusive LT lane, one exclusive RT lane, two through lanes$)$

$-\backslash (8\backslash \%\backslash )$ heavy vehicles

$-3\backslash \%$ downgrade

$-$ Parking on the right side $($only$)$ with $25$ movements$/$hour within $250$ ft of the stop line

$-25$ local buses$/$hour stopping to pick$-$up$/$drop$-$off passengers $($on the right$-$hand side$)$

$-100$ pedestrians$/$hour in each crosswalk

$-$ No bicycle traffic

$-$ CBD location

$-$ Protected LT movement

$-$ One receiving lane for left$-$ and right$-$turns

Estimate the saturation flow and capacity of each of the three lane groups on this approach. $[25$ points$]$
