6.14 A freeway segment currently has four 11-ft wide lanes and a 3-ft right shoulder in the southbound direction. It is operating in LOS B with a traffic density of 15.6 pc/mi/ln and a peak-hour factor of 0.85. The freeway is on level terrain with 15% heavy vehicles, and currently has no on- or off- ramps within a distance of three miles upstream and downstream of the mid-point of the analysis section. New interchanges are to be constructed that would result in 6 on- and off-ramps within the distance of three miles upstream and downstream of the mid- point of the analysis section and total traffic volume is projected to double, with the same percentage of heavy vehicles, and the peak-hour factor going to 0.95. What would the new LOS and density be after the interchange construction and new traffic conditions?

Question

6.14 A freeway segment currently has four 11-ft
wide lanes and a 3-ft right shoulder in the
southbound direction. It is operating in LOS B with
a traffic density of 15.6 pc/mi/ln and a peak-hour
factor of 0.85. The freeway is on level terrain with
15% heavy vehicles, and currently has no on- or off-
ramps within a distance of three miles upstream and
downstream of the mid-point of the analysis section.
New interchanges are to be constructed that would
result in 6 on- and off-ramps within the distance of
three miles upstream and downstream of the mid-
point of the analysis section and total traffic volume
is projected to double, with the same percentage of
heavy vehicles, and the peak-hour factor going to
0.95. What would the new LOS and density be after
the interchange construction and new traffic
conditions?

The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.
A new four-lane divided multilane highway (two lanes in each direction) is being planned with 12-ft lanes, 6-ft shoulders on both sides, and a 50-mi/h speed limit. One 3% downgrade is 4.5 mi long, and there will be 4 access points per mile. The peak-hour directional volume along this grade is estimated to consist of 1800 passenger cars, 140 SUTs, and 60 TTs. If the peak-hour factor is estimated to be 0.85, what level of service will this segment of highway operate under? What is the percent trucks - PT? What is the value of the passenger car equivalence factor - ET? What is the heavy vehicle factor - fHV? What is the median adjustment factor - fM?
True or False: Directional and lane distribution factors need to be considered to obtain initial traffic on the design lane.

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 temporary diversion has been constructed on a highway of -3% gradient due to major repairs that are being undertaken. Determine the speed limit that should be imposed on the diversion if drivers can see the sign inform ing them of the diversion at a distance of 400 ft from the diversion and the posted speed limit on the highway is 60 mph.
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.)
