Consider divided multilane highway in Congressional Avenue (fp = 0.98) that has six lanes (three lanes in each direction) and is on rolling terrain. The highway has 3.3m lanes with a 1.8m right-side shoulder and a 1.7m left-side shoulder. The posted speed limit is 85 kph. Formerly there were 1.2 access points per km, but recent development by Makati City Central Business District has increased the number of access points to 5.2 per km. Before development, the peak-hour factor was 0.95 and the directional hourly volume was 2500 vehicles with 9% large trucks and buses and 2% recreational vehicles. After development, the peak-hour directional flow is 3000 vehicles with the same vehicle percentages and peak-hour factor. What is the level of service before and after the development of Congressional Avenue? Round-off to the nearest value for the average passenger car speed in kph.

Please USE 3.0 instead of 2.5 for the rolling terrain. Thanks! 6.20 A divided multilane highway in a recreational area has four lanes (two lanes in each direction) and is on rolling terrain. The highway has 10-ft lanes with a 6-ft right-side shoulder and a 3-ft left-side shoulder. The posted speed is 50 mi/h. Previously, there were 4 access points per mile, but recent development has increased the number of access points to 12 per mile. Before development, the peak- hour factor was 0.95 and the directional hourly volume was 2200 vehicles with 13% heavy vehicles. After development, the peak-hour directional flow is 2600 vehicles with the same vehicle percentages and peak-hour factor. What is the level of service before and after the development?
A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions (fLw = 6.0 mph) 4 ft from the right edge of the traveled pavement (fic = 0.8 mph). There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. A directional peak-hour volume of 2000 vehicles (primarily commuters) is observed, with 600 vehicles arriving in the highest 15-min flow rate period. The traffic stream contains 12% large trucks (ET = 2.5) and buses and 6% recreational vehicles (ER = 2.0). 1.) What is the estimated free-flow speed of the traffic stream in mph (whole number, nearest 5)? 2.) What is the peak-hour factor 3.) What is the heavy-vehicle adjustment factor? 4.) What is the service flow rate? 5.) What is the service measure value if the average speed of the traffic stream is 65 mph
A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions 4 ft from the right edge of the traveled pavement. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. A directional peak-hour volume of 2000 vehicles is observed, with 600 vehicles arriving in the highest 15-min flow rate period. The traffic stream contains 18% heavy vehicles. What is the density of the traffic stream in pc/mi/In?
A new four-lane divided multilane highway (two lanes in each direction) is being planned with 12-ft lanes, 6-ft shoulders on both sides, and a 50-mi/h speed limit. One 3% downgrade is 4.5 mi long, and there will be 4 access points per mile. The peak-hour directional volume along this grade is estimated to consist of 1800 passenger cars, 140 SUTs, and 60 TTs. If the peak-hour factor is estimated to be 0.85, what level of service will this segment of highway operate under? What is the percent trucks - PT? What is the value of the passenger car equivalence factor - ET? What is the heavy vehicle factor - fHV? What is the median adjustment factor - fM?
True or False: Directional and lane distribution factors need to be considered to obtain initial traffic on the design lane.
Problem 2. New freeway is being designed on a level terrain, free-flow speed 70 mph 12-ft lanes, 6-ft lateral clearance Peak hour volume 2700 veh, 12% heavy vehicles PHF = 0.92 FIND: Number of lanes for LOS C
A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
An eight-lane freeway has a basic freeway segment on rolling terrain. It has 12-ft lanes with a 4-ft right shoulder. There are seven ramps within the six-mile segment. The directional peak traffic volume is 5200 veh/h with 6% trucks and 2% buses. The PHF is 0.90. Calculate the FFS, vp , and determine the LOS
A 3.25-mile segment of undivided, four-lane highway is primarily on level terrain. The highway segment does, however, contain one sustained grade of 2.5% that is 3,200 ft long. Other relevant information include: Base free-flow speed = 65 mph %3! 11-ft lanes • 4 ft clearance at the roadside (right side) • 20 access points/mile Peak-hour volume = 1,900 veh/h 13% trucks; 2% RVs • PHF = 0.90 • Familiar facility users At what LOS is the highway expected to operate? (Hint: Three different analyses will be needed: a) the level terrain portion of the highway, b) the 2.5% upgrade portion of the highway, and c) the 2.5% downgrade portion of the highway.)
