A segment of four-lane freeway (two lanes in each direction) has a 3% upgrade that is 450 m long followed by a 300-m 4% upgrade. It has 3.6 m lanes and 0.9 m shoulders. The directional hourly traffic flow is 2000 vehicles with 5% large trucks and buses (no recreational vehicles). The total ramp density for this freeway segment is 1.45 ramps per kilometer. If the peak hour factor is 0.9 and all of the drivers are regular users, what is the level of service of this compound grade freeway segment?

A freeway segment has the following characteristics:
3 lanes in each direction
Lane width = 11 ft
Right shoulder width (lateral clearance) = 4 ft
There is 1 interchange within 3 miles downstream, and 2
interchanges within 3 miles upstream.
