Volumes

Volume usually is the dimensional quantity that involves the evaluation of any three-dimensional figure enfolded inside a closed space. The SI unit (International System of Units) of volume is m3 and the dimensional unit of volume is [L3]. For estimation of the volume of any figure, various formulae are used. Another application of volume includes the reference in the sound levels, the higher the sound intensity, the louder the sound heard, and hence, the larger the volume. The SI unit of sound volume is decibels (dB).

Question

Given the following prevailing traffic and roadway conditions on a uniform 0.625-mile section of a six-lane (3 lanes each direction) rural freeway in the west-bound direction during a regular weekday:

- **Hourly volume, V** = 4400 vehicles per hour (vph)
- **PHF** = 0.90
- **Heavy vehicles** = 20% (70% single unit trucks and 30% tractor-trailers)
- **Lane width** = 11 feet
- **Terrain** = 3.5% upgrade
- **Shoulder width** = 5 feet
- **No entry or exit ramps** within 3-miles upstream and 3-miles downstream of the midpoint of the analysis segment

Determine the capacity and level of service (LOS) on this section of the freeway.

A long segment of suburban freeway is to be designed on level terrain. The level segment, however, is followed by a 4.5% grade, 2.0 miles in length. If the DDHV is 2,500 vehicles per hour with 15% trucks (standard mix), how many lanes will be needed on the (A.) Upgrade, (B.) Downgrade, (C.) Level terrain segment to provide for level of service C? Lane widths and lateral clearances may be assumed to be 12 feet and 6 feet, respectively. Ramp density is expected to be 1.0 ramps per mile. The PHF is 0.92. Good weather, no incidents, no work zones, and regular users of the facility may be assumed.
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
A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
A 3.25-mile segment of undivided, four-lane highway is primarily on level terrain. The highway segment does, however, contain one sustained grade of 2.5% that is 3,200 ft long. Other relevant information include: Base free-flow speed = 65 mph %3! 11-ft lanes • 4 ft clearance at the roadside (right side) • 20 access points/mile Peak-hour volume = 1,900 veh/h 13% trucks; 2% RVs • PHF = 0.90 • Familiar facility users At what LOS is the highway expected to operate? (Hint: Three different analyses will be needed: a) the level terrain portion of the highway, b) the 2.5% upgrade portion of the highway, and c) the 2.5% downgrade portion of the highway.)
