An urban freeway is to be designed using the following information.

AADT $=52,100ve\frac{h}{?}$ day

K $($proportion of AADT occurring during the peak hour$)$: $0\mathrm{.}11$

$D($proportion of peak hour traffic traveling in the peak direction$)$: $,0\mathrm{.}65$

Trucks: $,8\%$ of peak hour volume

PHF $=0\mathrm{.}96$

Lane width: $12ft$

Shoulder width: $,10ft$

Total ramp density: $,0\mathrm{.}5$ interchange$/$mile; all interchanges are to be cloverleaf interchanges

Terrain: rolling

Determine the number of lanes in the peak direction required to provide LOS C$.($Assume commuter traffic and assume no RVs$.)$
