- A 6-lane 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 aboutAn existing four-lane freeway in rural area is with the following :information Lane width 3.5m, 0.9m lateral clearance, 1800 veh/hr peak hour volume, PHF=0.9, interchange density =0.90, 5% trucks, 5% buses and the road is within a mountainous terrain. Then based on the HCM procedure, the service flow rate (pc/h/In) isOne segment of a Class I two-lane highway is on level terrain and has an hourly volume of 1200 veh/h (total for both directions), a directional traffic split of 50/50, and PHF = 0.92, and the traffic stream contains 5% large trucks, and 2% buses. It has 11-ft lanes, 2-ft shoulders, access frequency of 10 per mile, 50% no-passing zones, and a base FFS of 55 mi/h, determine the level of service for this two-lane highway segment.
- a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 3.3 meter lanes with a 1.2 meter right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 8% 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 2.4 kilometers long if the speed limit is 90 km/h and there are 9 access points per mileA 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?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?
- One segment of a Class I two-lane highway is on rolling terrain and has an hourly volume of 950 veh/h (total for both directions), a directional traffic split of 70/30, and PHF = 0.85, and the traffic stream contains 6% large trucks, 3% buses, and 6% recreational vehicles.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 mileA 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) in a scenic area has a measured free-flow speed of 55 mi/h. There are 7% SUTs and 7% TTs 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, what value for the peak-hour factor was used? Answer: Peak Hour Factor = 0.731A freeway is being designed to carry a heavy volume of 5000 veh/h on a regular weekday in rolling terrain. If the PHF is 0.9 and the traffic consists of 90% passenger cars and 10% trucks, determine the number of 12-ft lanes required in each direction if the highway is to operate at level of service C. The free-flow speed is 70 mi/h, there is no lateral obstruction, and interchanges are 3 mi apart.traffic engineering - Q / A freeway is being designed to carry a heavy volume of 5000 veh / h on a regular weekday in rolling terrain . If the PHF is 0.9 and the traffic consists of 90 % passenger cars and 10 % trucks , determine the number of 12 - ft lanes required in each direction if the highway is to operate at level of service C. The free - flow speed is 70 mi / h , there is no lateral obstruction , and interchanges are 3 mi apart .
