Q3/ Show how to determine the number of lanes for a multilane minor arterial highway is being designed through a mountain rural area required to serve a current ADT of 5000 ypd. The following data should be used in solution: annual growth rate 4%, design, construction period = 22 years, percent of trucks 10 (pc equivalent factor= 2.0), peak hour factor 90% and the directional distribution factor 60%. %3D
H.W. For a two-way highway with information shown below determine future ADT and DHV. a design 20 years & construction on period of years, current ADT is 5500 vpd, annual growth rate of traffic is 4.5% per year.
It is required to design a rural highway in Baghdad city, the anticipated peak hourly volume for the highway section under consideration within one year is shown in table below: Hour No. 5th 15th 20th 30th 1st 4000 3750 3300 45th 50 Volume (veh./hr) 3100 2850 2650 Find the required No. of lanes for this highway (PHF=0.85; DDF 0.6; Truck 10 percent,design service flow for one lane 1080 pc/hr/lane) 40th 2700 2600
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.
For a two-way highway with information shown below determine future ADT and DHV. a design 20 years & construction on period of 5 years, current ADT is 5500 vpd, annual growth rate of traffic is 4.5% per year.
4) Determine the level of service (LOS) for a freeway segment with the following data. Show all steps involved. Demand volume (3452 vehicle per hour) ● ● ● ● ● ● ● 1 Number of lanes (3 lanes in one direction) Width of lanes (11ft per lane) Lateral clearance on the right side of the freeway (4 ft) Total ramp density (2 miles between ramps, or 0.5 ramps per mile) Percent of heavy vehicles (5% trucks/buses and 0% recreational vehicles) Peak hour factor (0.927) I Terrain (level) Driver population factor (familiar drivers)
4. TXDOT is working on the design of I-69 north of Victoria. They project a demand volume of 52,000 vehicles per day with a K factor of 0.12 and a directional distribution of 56/44 in level terrain with a target LOS of B and 17% trucks and buses. They plan to have roughly one diamond interchange every 2 miles. What number of lanes is required to achieve these design requirements? What LOS would occur for a typical 4-lane rural interstate design? DHV = AADT * K * D DHV – design hourly volume AADT - average annual daily traffic K- peak hour adjustment factor D- directional distribution (make design conservative)
The DDHV fora given highway project is 2200 veh/h and the design capacity is 1450 veh/h/ln. The calculated number of lanes in this case is about
A section of a two-lane rural highway is expected to have the following characteristics: Design speed of 80 km/hr, lanes of 3.6 m, walks of 1.2 m, mountainous terrain, 70% of sections without passing distance and length of 7 km. Of traffic 1,321 veh/hr: distribution by direction of 60/40, 10% of trucks, 10% of buses and 80% of light vehicles. Say what is the capacity of the section and the maximum intensity for the NS
