Problem A:

A four$-$lane freeway $($two lanes in each direction$)$ is on rolling terrain with $10-ft$ lanes, with obstructions $3ft$ from the right edge of the traveled pavement, and $6$ ramps within $3$ miles upstream and $3$ miles downstream of the midpoint of the analysis segment. A directional weekday peak$-$hour volume of $2700$ vehicles is observed with $680$ vehicles arriving in the most congested $15-$min period. If the traffic stream has $5\%$ single unit trucks and $3\%$ tractor trailers determine the level of service using:
