A four-lane freeway (two lanes in each direction) is located on rolling terrain and has 12-ft lanes, no lateral obstructions within 6 ft of the pavement edgess, and there are two ramps within three miles upstream of the segment midpoint and three ramps withing three miles downstream of the segment midpoint. The traffic stream consists of cars, buses, and large trucks (no recreational vechicles). A weekday directional peak-hour volume of 1800 vehicles (familar users) is observed, with 700 arriving in the most congested 15 min period. If a level of service no worse than C is desired, determine the maximum number of large trucks and buses that can be present in the peak-hour traffic stream.
