The AADT for certain road sections is 25,000 vehicles/day. If the route is classified as an urban radial highway, what is the expected directional design hour volume range

An eight-lane freeway (four lanes in each direction) is on rolling terrain and has 11-ft lanes with a 4- ft right-side shoulder. The total ramp density is 1.5 ramps per mile. The directional peak-hour traffic volume is 5400 vehicles with 11% heavy vehicles. The peak 15-minute volume is 1421 vehicles. What are the freeway’s density and level of service

A 5% upgrade on a six-lane freeway (three lanes in each direction) is 1.25 mi long. On this segment of freeway, there is 3% SUTS and 7% TTs, and the peak-hour factor is 0.90. The lanes are 12 ft wide, there are no lateral obstructions within 6 ft of the roadway, and the total ramp density is 1.0 ramps per mile. What is the maximum directional peak-hour volume that can be accommodated without exceeding LOS C operating conditions in veh/h? Round of your answer to whole number. Blank 1

Determine the value of PTSF for a 6-mile two-lane highway in rolling terrain. Traffic data are as follows: • Volume = 1600 veh/h (two-way) • Percent trucks = 14% • Percent RVs = 4% • Peak hour factor = 0.95 • Percent directional split = 50 - 50 • Percent no-passing zones = 50

Consider the problem of traffic flow on a three-lane (one direction) freeway which 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 several hours. It is estimated that the capacity at the work zone will be reduced by 30 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 130 veh/mi/ln. It is estimated that the demand flow on the highway during the emergency repairs is 86 percent of the capacity. Using the deterministic approach, determine the following for the expected repair periods of 1 h, 1.5 h, 2.5 h, 2.75 h, and 3 h.

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?

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 freeway is to be designed as a passenger-car-only facility for an AADT of 35000 vehicles per day. It is estimated that the freeway will have a free flow speed of 70mph. The design will be for commuters and the peak hour factor is estimated to be 0.85 with 65% of the peak hour traffic traveling in the peak direction. If the k-factor for this freeway is 0.148, determine the directional design hourly volume. 3367 4403 2862 5015

Read the question carefully and give me right solution.. Thank you

A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 3.3 m wide, the right-side shoulder is 1.2 m wide, and there are five ramps within five kilometers upstream of the segment midpoint and3 ramps within five kilometers downstream of the segment midpoint. The highway is on rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. Determine 15-min volume within hour of analysis for these conditions. Hint: Use LOS Criteria for Basic Freeway Segments
