- Determine the L.O.S of the road if PHF = 0.88, D= 60%, K=O.11, V=115 kph? For an Existing 4 lane freeway having the following features: • Lane and shoulder width = 12 ft, 6 ft, weekday commuter • Percent of trucks and buses = 8% and 4% respectively and Et =2.5, Eb =2.2• AADT = 35200 veh/day, Assume lane capacity * 2000 pc/hrA new 50 km freeway was required to constructed between two cities with design speed 70 mph, the expected 20 year DHV was 12000 vph on a regular weekday, rolling terrain, PHF pf 0.95, directional split of 65%, a heavy vehicle adjustment factor of 0.85 and the suggested L.O.S to reach end design period is B (v/c=0.54), if the one lane cost per kilometer was 25000$. What will be the saving of money if the operating L.O.S at the end of design period change to be L.O.S C (c/v=0.77)?Assume: the lane and shoulder width are ideal, lane capacity * 2000 pc/hrAn urban freeway presently has three 12-ft lanes on a 3 percent upgrade 1.75 mi long. The traffic includes 8 percent trucks and buses (recreational vehicles are negligible). There are no lateral obstructions. Design speed is 70 MPH. (a) What is the present capacity of the upgrade? (b) How much could the capacity be increased by widening and remarking the existing traveled way to provide four 10-ft lanes up the grade?
- A particular roadway segment has a 6000-ft section of 3% upgrade, followed by a 5000-ft section of 5% upgrade. The traffic on the road includes 8% trucks and 4% recreational vehicles. Determine the PCEs.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 workCivil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?
- What is the capacity of a freeway with 2-lanes in one direction, 10 ft lanes, 1 ft shoulders and 4 ramps within a six-mile stretch? Show Work Correct Answer: 2335A proposed highway is to be designed with adequate shoulder and clearance in a level terrain with the following: AADT = 25,000 pcu/day D% = 65% K = 9%. Estimate the number of lanes that will provide LOS C.A six-lane freeway (three lanes in each direction) in a scenic area has a measured free-flow speed of 55 mi/h. The peak hour factor is 0.80, and there are 8% large trucks and buses and 6% recreational vehicles in the traffic stream. One upgrade is 5% and 0.5 mi long. An analyst has determined that the freeway is operating at capacity on this upgrade during the peak hour. If the peak-hour traffic volume is 3900 vehicles, b.) Determine vp
- Determine the LOS on a regular weekday on a 1.5-mile segment of an 8-lane freeway (four lanes in each direction) in rolling terrain. Use the following data.A four-lane freeway carries 2,200 vehicles northbound (NB) in the peak hour. The freeway is relatively steep (2 miles of +4.5% grade NB). Free flow speed is measured at 68.2 mph. 15% of the vehicles are heavy trucks and 30% of those heavy trucks are SUT and the other 70% are TT. The PHF is 0.90. Determine ET, fhv, vp, BP, c, S, D, and the Level of Service (LoS)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?
