A four-lane urban freeway is rolling on rolling terrain with 12-ft lanes, obstructions 2-ft from the right edge of the traveled pavement, and nine ramps within three miles upstream and three miles downstream of the midpoint of the analysis segment. The traffic stream consists primarily of commuters. A directional weekday peak-hour volume of 2400 vehicles is observed with 800 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and buses and recreational vehicles, determine the level of service.
