Problem $5\mathrm{.}2$

A six$-$lane rural freeway has four ramps in $6$ miles, $12-ft$ lanes, $4-ft$ left shoulder, $10-ft$ right shoulder, and is on a $3\mathrm{.}8\%$ grade for $1\mathrm{.}3$ miles. The traffic demands are $1500$ vehicles in peak $15$min,$10\%$ trucks, and PHF $=0\mathrm{.}9.$

What is the current LOS?

At $3\%$ per year traffic growth, when will this segment reach capacity?
