Two$-$Lane Highway Operation

Consider Class I two$-$lane highway with the following characteristics:

$50\%$ no passing zones

$1600vph$ both ways

$15\%$ trucks and buses,

$4\%$ RVs $0\mathrm{.}95$ PHF

$4"$ shoulders

$11"$ lanes

$60mph$ BFFS

$6$ miles rolling terrain $20$ access points$/$mile

$-$Determine the operational level of service of the Highway using two$-$way segment Analysis. If LOS is beyond D$,$ Propose a solution and evalute the LOS after this Solution.
