Question 4 One stretch of two-lane two-way roadway that traverses through level terrain is expected to carry 1400 vehicle per hour. Determine the Level of Service (LOS) in the peak direction for the road based on average travel speed (ATS) if the characteristics of the roadway are as follows: Table Q4-1 Percentage of Trucks Percentage of Recreational Vehicle Peak Hour Factor 10 0.97 60:40 60 Percent Directional Split Percent no-passing Zone Lane Widths Shoulder Widths Design Speed Road Length Access Points 3.35 m 1.2 m 96 km/h 8 km 10 access points per km State all assumption (if any) used in calculation..
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)
An undivided multilane highway segment has the following characteristics: • Six lanes (three lanes in each direction); Lane width of 11 ft; • Speed limit of 45 mph; Right shoulders is 4 ft wide; • There are approximately 25 access points over a 2-mile section of this roadway, in each direction. Calculate the FFS at this highway section and then determine the level of service (LOS) when the flow rate is 1100 pc/h/In. (Write the answer for the LOS in the box below).
You are designing a freeway as a passenger-car-only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a peak-hour factor of 0.88, and a directional distribution of 0.65. day. It is estimated that the freeway will have a free flow speed of 70mi/h. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume. Use k =0.11.
A section of rural 2 lane highway is to be designed to carry a peak hour volume of 1500 on a level terrain. Determine the level of service at which it will operate using the following data: V Lane width = 11 ft V No passing zone = 20% Directional split = 60/40 V Decimal fraction of trucks = 0.10 V Decimal fraction of recreational vehicles = 0.04 V Decimal fraction of buses = 0.01 Shoulder width =6 ft PHF = 0.95
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.
You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume (K60 = 0.11). The answer is a/an -ane freeway.
A 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?
