A four lane basic freeway segmA four$-$lane basic freeway segment on level terrain is being redesigned. The current roadway has $12ft$ lanes with $4ft$ shoulders. The proposed alignment would expand to six $11-$ft lanes with $2ft$ shoulders. The road carries $3000$ vehicles in the peak hour in one direction, with $925$ coming in the peak $15$ minutes. The truck mix is $\frac{70}{30}$ and maks up $10\%$ of traffic. What is the density and LOS before and after the proposed change?
