Question $1.$ A four$-$lane freeway $($two lanes in each direction$)$ is on rolling terrain with $11-$ ft lanes, a $5-$ft right$-$side shoulder, interchange $($or ramp$)$ spacing of one every $10$ miles $,$ and a $\backslash (60-\backslash$mathrm$\{$mi$\}/\backslash$mathrm$\{$h$\}\backslash )$ base free$-$flow speed. During the peak hour, there are $\backslash (12\backslash \%\backslash )$ large trucks and buses and no recreational vehicles. The peak$-$hour factor is $0\mathrm{.}88$ and the driver population adjustment is determined to be $0\mathrm{.}90($which means that drivers are mostly familiar with the roadway$).$ The freeway currently operates at capacity during the peak hour, in the direction in question. If an additional $11-$ft lane is added $($each direction$),$ and all other factors stay the same, what will be the new level of service?
