A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 4-ft shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has only regular users, there are 8% large trucks and buses (no recreational vehicles), and it is on rolling terrain with a peak-hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway's AADT?

A six-lane freeway (three lanes in each direction in mountainous terrain has 10-ft lanes and obstructions 1ft 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 commuter with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service?
(a) A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 11 ft wide, the right-side shoulder is 4 ft wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rollingterrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. Determine the hourly volume for these conditions.
A basic segment of a rural freeway has the following characteristics: • Four-lanes (two lanes in each direction)%3B There is one ramp within 3 miles upstream, and 2 ramps within 3 miles downstream; 10-ft lanes; Right shoulder width of 4 ft; • Level terrain;. 10% trucks and 5% buses in the vehicle stream. Calculate the FFS at this freeway section and then determine the level of service (LOS) when the flow rate is 1740 pc/h/In. (Write the answer for the LOS in the box below).
QUESTION 1 A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.
A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 5 ft from the right edge. There are zero ramps within three miles upstream of the segment midpoint and one ramp 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?
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.
A four-lane freeway (two lanes on each direction) is located on mountainous terrain with 11-ft lanes, a 5-ft right-side shoulder, and a 3-ft left-side shoulder, and a 60- mph design speed. The freeway currently operates at capacity during the peak hour. If an additional 11-ft lane is added, and all other factors stay the same, what will the new level of service be?
A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 3.3 m wide, the right-side shoulder is 1.2 m wide, and there are five ramps within five kilometers upstream of the segment midpoint and3 ramps within five kilometers downstream of the segment midpoint. The highway is on rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. Determine 15-min volume within hour of analysis for these conditions. Hint: Use LOS Criteria for Basic Freeway Segments
A four-lane freeway (2 lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 12 ft wide, the right-side shoulder is 4 ft wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. Determine the D in pc/mi/h and vp in pc/hr/ln.
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 four-lane rural freeway segment has a 510 m grade length of 2% upgrade followed by a 630 m grade length of 3%. The freeway has 3.4-m lane, 1.5m left-shoulder lateral clearances and interchanges spaced at every 25 km. During the peak hour, there are 6% trucks, 2% buses, 2% recreational vehicles and the rest are passenger cars. Driver population adjustment is determined to be 0.90, peak hour factor is 0.90 and the BFFS is 110 km/h. At present, the freeway operates at capacity during the peak hour in the direction in question. If an additional 3.4 m lane is introduced, and all other factors stay the same, what will be the new level of service?
A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 3.5m wide, the right-side shoulder is 1.2 m wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. a) Determine the hourly volume for these conditions. b) At one point along this freeway, there is a 4% upgrade with a directional hourly traffic volume of 5000 vehicles. How long can this grade be without the freeway LOS dropping to F?
