A segment of four-lane freeway (two lanes in each direction) has a 3% upgrade that is 1500 ft long followed by a 1000-ft 4% upgrade. It has 12-ft lanes and 3-ft shoulders. The directional hourly traffic flow is 2000 vehicles with 3% Single-Unit Trucks (SUTs) and 3% Tractor Trailers (TTs). The total ramp density for this freeway segment is 2.33 ramps per mile. If the peak-hour factor is 0.90, what is the level of service of this compound-grade freeway segment
