A six lane urban freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 5 ft from the right edge. For every mile of freeway, there is one interchange. The traffic stream consists of mostly commuters with a peak hour factor of 0.84, peak hour volume of 2500 vehicles, and 4% recreational vehicles. What is the LOS? Assume base free flow speed of 70 mph

A six-lane freeway with three lanes in each direction is on a level terrain and has 11-ft lanes with a 4-ft right-side shoulder. The total ramp density is 2 ramps per mile. The directional peak-hour traffic volume is 5400 vehicles with a peak-hour factor of 0.95 and all familiar users. The traffic stream includes 5% trucks and another 5% buses and no recreational vehicles. The city has decided to ban all heavy vehicles from using the freeway during the peak...

Problem Statement: A four-lane (two-lanes in each direction) freeway is on rolling terrain with 11-ft lanes, a 5-ft lateral clearance on right side and 3-ft lateral clearance on the left side of the traveled pavement. The measured free-flow speed is 60-mph. During the peak hour there are 12% large trucks and buses and 6% recreational vehicles. The freeway currently operates at capacity during the evening peak hour. If an additional 11-ft lane is added, and all other factors stay the same,...

A six-lane freeway with three lanes in each direction has regular weekday users. The lanes are 12 feet wide, the right-side shoulder is 2 ft wide, and there are two ramps within 3 miles upstream and two ramps within 3 miles downstream of the segment midpoint. The highway is on rolling terrain with 12% large trucks and buses and 2% recreational vehicles. The peak hour factor is 0.85. Determine the maximum hourly volumes that can be sustained at LOS C...

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,...
