A four-lane freeway carries 2,200 vehicles northbound (NB) in the peak hour. The freeway is relatively steep (2 miles of +4.5% grade NB). Free flow speed is measured at 68.2 mph. 15% of the vehicles are heavy trucks and 30% of those heavy trucks are SUT and the other 70% are TT. The PHF is 0.90. Determine ET, fhv, vp, BP, c, S, D, and the Level of Service (LoS).
