It is estimated that the freeway will have a traffic demand of 75.000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88 and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least level of service D using the 30th highest annual hourly volume (K30+ 0.12). The answer is a number of lane freeway.
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?
Question - 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: 112 km/h; no lateral obstructions; rolling terrain; total ramp density of 0.5 ramps /km. Determine: Number of 3.6 m lanes required in each direction. Please give the correct answer
A 6-lane new urban freeway is suggested to be designed with the following data: F.ADT = 45000 vpd, design hour factor= 0.12 and directional split = 65%. Rolling terrain, 10% trucks, 5% buses, 6% Rvs, PHF is 0.91 and all traffic are commuters. Then based on the HCM 2000 procedure, the equivalent passenger-car hourly flow rate is about ..... .... ..... .. а. 1410 b. 2105 O C. none d. 1650 е. 1255
a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 11-ft lanes with a 4-ft right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 10% large trucks and buses and 2% recreational vehicles. the driver population factor has been estimated at 0.95. what will the los on this highway be on a 4% upgrade that is 1.5 miles long if the speed limit is 55 mph and there are 15 access points per mile
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?
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?
