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.
An eight-lane freeway section is designed to have a lane width of 10 ft, right-side shoulder width is 4 ft, and 5 ramps over a 2-mile-long centerline. What is the free-flow speed for this freeway section? a. 75 mph b. 70 mph c. 65 mph d. 60 mph
A delivery truck passes thru the expressway exit ramps at a design velocity of 50 kph. connects with a local road to allow ram traffic to turn right without stopping at an acceleration of 1.57 m/sq.s. The turning roadway has stabilized shoulders on both sides and provides for a one-lane one-way operation with no provisions for a passing stalled vehicle. Super elevation on the turning roadway is 0.08. Determine the minimum radius of curvature for the ramp in meters.
A new basic freeway segment will have 3 lanes in each direction. The left and center lane each has a width of 12 ft while the width of the right lane is 13 ft. The left shoulder is 4 ft while the right shoulder is also 4 ft. There are 2 interchanges within 6 miles (3 miles upstream and 3 miles down stream).The site has level terrain, the design speed is 80 mph the hourly design volume is 5250 veh/h, which includes 9.0% trucks and buses. The peak hour factor is 0.870. Calculate FHV, VP, FFS, LOS Show all work
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 rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. a.) Determine the Free Flow Speed
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?
A 5% upgrade on a six-lane freeway (three lanes in each direction) is 1.25 mi long. On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak- hour factor is 0.90, and all drivers are regular users. The lanes are 12 ft wide, there are no lateral obstructions within 10 ft of the roadway, and the total ramp density is 1.0 ramps per mile. A bus strike will eliminate all bus traffic, but it is estimated that for each bus removed from the roadway, seven additional passenger cars will be added as travelers seek other means of travel. a.) What is density, before the bus strike? b.) What is the volume-to-capacity ratio, before the bus strike? c.) What is the level of service of the upgrade segment before the bus strike? d.) What is density, after the bus strike? e.) What is the volume-to-capacity ratio, after the bus strike? f.) What is the level of service of the upgrade segment after the bus strike?
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?
