A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. 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 level of service? (Write the letter only)

A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?

An existing Class I two-lane highway is to be analyzed to determine the level of servicein each direction, given the following information:Traffic data:PHV = 600 veh/h60% in the peak direction8% trucks2% recreational vehiclesPHF = 0.86No passing zones: 40%Geometric data:Rolling terrainBFFS = 55 mi/h (88 km/h)Lane width = 11 ft (3.3 m)Shoulder width = 2 ft (0.6 m)8 access points per mile (5 access points per km)
Eight lane urban freeway is on mountainous terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the heavy vehicle adjustment factor. Round your answer to 3 decimal places. Exclude the unit in the answer box.
A four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?
Traffic volume is 2578 veh/hr with 687 vehicles arriving in peak 15 minutes.There are tow lanes, 12 percent trucks(30/70 split for SUT/TT), the length of the road is 1.8 miles long with a 3.5 percent grade. calculate the analysis flow rate?
A freeway is to be designed to provide LOS C for the following conditions: design hourly volume of 5600 veh/h; PHF: 0.92; trucks: 6%; free flow speed: 70 mi/h; no lateral obstructions;rolling terrain; total ramp density of 0.75 ramps per mile.Determine: whether eight (four in each direction) 12 ft lanesare enough to provide LOS C.
