Problem $3($Chapter $9)$:

A $10mi$ segment of a rural Class I two$-$lane highway in roling terrain has a design speed of

$60mph$ in both directions. The demand volume is $1600$ peph total for both directions. The

lanes are $11ft$ wide with $2ft$ shoulders. The peak hour factor is $0\mathrm{.}95,$ and there are ne

possing zone for BO$\%$ of the distance in both directions. The percentages of trucks and RVs

in the traftic stream arc $14\%$ and $0\%,$ respectivcly. There are $20$ acocss points per mile.

Note: calculations must be provided.
