A eight-lane multilane highway (four lanes in each direction) currently operates at maximum LOS C conditions. The measured FFS is 50 mi/h. The highway is on rolling terrain with 11% SUTS and 11% TTs, and the peak-hour factor is 0.92. If 13.4% of all directional traffic occurs during he neak hour determine the total directional traffic vvolume

A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions 4 ft from the right edge of the traveled pavement. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. A directional peak-hour volume of 2000 vehicles is observed, with 600 vehicles arriving in the highest 15-min flow rate period. The traffic stream contains 18% heavy vehicles. What is the density of the traffic stream in pc/mi/In?
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
An eight-lane freeway has a basic freeway segment on rolling terrain. It has 12-ft lanes with a 4-ft right shoulder. There are seven ramps within the six-mile segment. The directional peak traffic volume is 5200 veh/h with 6% trucks and 2% buses. The PHF is 0.90. Calculate the FFS, vp , and determine the LOS
