A California freeway has four lanes in each direction and carries a traffic volume of 4000 veh/h. The lane width is 11 ft, right shoulder lateral clearance is 5 ft, and there are four interchanges in every six miles of this freeway. Each interchange has two ramps, one for entry and one for exit. There is a 1 mile long section of this freeway that has a 6% upgrade. It is known that on this segment 5% of the traffic is SUTs and 5% is TTs. Peak-hour factor (PHF) is 0.90. Determine the LOS for this segment.

A two-lane rural highway carries a peak hour volume of 465 (vph) and has the following characteristics: Roadway: 60mph design; 11 foot lanes, 2 foot shoulders; rolling terrain; 60% no-passing zones; length = 3 miles. Traffic: 70/30 directional split; 4% trucks; 2 percent recreational vehicles; 1 percent buses; PHF = 0.95 a) What Level of Service will the highway operate under during peak periods? b) What is the capacity of the highway? Explain why this is less than 2,800 (vph)?
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: 2335
A section of the roadway has the following flow-density relationship q=50k-0.4k^2 [q is in veh/h unit and k in vh/mile]. What is the flow, speed,and density at capacity? What is the density when highway is at one-third of its capacity.
The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.
Traffic flow on a three-lane (one direction) freeway can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 25 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 60 mi/h and the jam density is 140 veh/mi/ln. If it is estimated that the demand flow on the highway during the emergency repairs is 85 percent of the capacity, using the deterministic approach, determine the following. the maximum queue length (in veh) that will be formed the total delay (in h) the number of vehicles that will be affected by the incident the average individual delay (in min)
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, c.) what value for the driver population factor was used? (Express in three decimals)
A four-lane freeway with the following characteristics: ten foot travel lanes lateral obstructions at 0 feet at the roadside total ramp density is 4.5 ramps/mile rolling terrain The roadway has a current peak demand volume of 3500 veh/h. The peak hour factor is 0.95 and there are no trucks, buses, or RVs in the traffic stream because the roadway is classified as a parkway and such vehicles are prohibited. At what level of service will the freeway operate during its peak period of demand?
If Vf = 2327 VPH with 9% trucks, VR1 = 653 VPH with 5% trucks, and VR2 = 594 VPH with 8% trucks, what is the passenger car equivalents (Vpcph) of the onramp? Assume that the roadway is urban.

An 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?
The predicted traffic mix of a proposed four-lane urban non-interstate freeway is as follows. Passenger cars = 78% Single-unit trucks: 2-axle, 5,000 lb/axle = 12% 2-axle, 9,000 lb/axle = 4% 3-axle or more, 23,000 lb/axle = 3% Tractor semitrailers and combinations: 3-axle, 20,000 lb/axle = 3% The projected AADT during the first year of operation is 3,900 (both directions). If the traffic growth rate is estimated at 3 percent and the CBR of the subgrade is 7.5, determine the depth of a full-asphalt pavement (in inches) using the AASHTO method and n = 20 years. The resilient modulus of the asphalt (EAC) is 320,000 lb/in2. Assume mi for the subgrade is 1 and the percent of traffic on the design lane is 42 percent, pt = 2.5, and SN = 4. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0. Assume the design lane factor fd is 0.42. (Use single-axle load equivalency factors for 2-axle vehicles and tandem-axle load equivalency…
