Estimate the service flow rate for level of service D for a six-lane freeway (three lanes in each direction with 12-ft (3.6m) lanes and obstructions 6 ft (1.8 m) from the edge of pavement. The section is to accommodate 5 percent single unit trucks and 5 percent tractor trailer trucks. The design speed is 75 mph, and the section has a +3 percent grade that is 0.7 mile long. NOTE: assume the road is located in a rural region (i. e. TRD = 0.5 ramps / 1 mile).
