Eight lane urban freeway is on mountainous terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the heavy vehicle adjustment factor. Round your answer to 3 decimal places. Exclude the unit in the answer box.
which type of urban road would have free-flow traffic characteristics? 1. Arterial 2. Local 3. Freeway 4. Collector
A multi-lane Minor Arterial is being designed through a level urban area. The current daily volume = 8000 vpd in both directions with 10% Trucks, peak hourly factor 90%and a 60% directional distribution factor. How many lanes are required?
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)?
Find level of service (LOS) for an old freeway in Basrah city with the following characteristics: (free flow speed (FFS) = 65 (mi/hr), peak hour factor (PHF) = 0.80, umber on lanes (N) = 3 in one direction, factor of heavy vehicles (fív) = 0.90 and traffic volume (V) = 2200 (veh/hr).
An 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) is
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.
