2) A 6-lane divided highway has a design speed of 65 mph and the following typical section: Grassed median: Median shoulders: Lanes: Right-side shoulders: 14 ft. wide 4ft. wide 12 ft. wide, 3 lanes directional 10 ft. wide Centerline Degree of Curvature, D is 3 45 If single face concrete barrier be installed along the highway without encroaching on the required horizontal sight distance, how far (at minimum) from the roadway centerline should the face of the barrier be located?
A six-lane divided highway (three lane in each direction) is on rolling terrain with two access points per mile and has 10-ft. lanes, with a 5-ft. shoulder on the right side and a 3-ft. shoulder on the left side. The peak-hour factor is 0.80, and the directional peak-hour volume is 3000 vehicles per hour. There are 6% large trucks, 2% buses, and 2% recreational vehicles. A significant percentage of nonfamiliar roadway users are in the traffic stream (the driver population...
Problem 4. A section of a two-lane highway has 12-ft lanes and a design speed of 75 mi/h. The section contains a vertical curve and a horizontal curve. The vertical curve connects a-2.5% grade and a +1.5% grade. The PVT of this vertical curve is at station 36 + 50. The PC of the horizontal curve is located 294 ft before the PVC of the vertical curve. The horizontal curve has superelevation of 8% and central angle of 38 degrees....
