$9-20$ An existing Class I two$-$lane highway is to be analyzed to determine the level of

service in each direction, given the following information:

Traffic data:

$PHV=600ve\frac{h}{h}$

$60\%in$ the peak direction

$8\%$ trucks

$2\%$ recreational vehicles

$PHF=0\mathrm{.}86$

No passing zones: $40\%$

Geometric data:

Rolling terrain

$BFFS=55m\frac{i}{h}$

Lane width $=11ft$

Shoulder width $=2ft$

$8$ access points per mile

Show Solution to answer:

ATS $=41\mathrm{.}30$ mph$,$ PTSF $=63\mathrm{.}86\%,$ LOS D
