Problem $5\mathrm{.}3$

A six$-$lane freeway has a right$-$side off$-$ramp, ideal geometry, level terrain, and $70-mph$ FFS$.$ The ramp itself is designed at a FFS of $35-mph$ ramp with a $950-ft$ deceleration lane. The freeway mainline has $4850vph$ and the off$-$ramp volume is $800vph.$ An upstream on$-$ramp $\frac{1}{2}$ mile away has $900vph$ entering volumes. All traffic streams have $9\%$ trucks and $PHF=0\mathrm{.}93.$

Determine the density, speed, capacity, and LOS at RIA, the outer lane, and for the overall cross section.
