A curved highway has only one lane with a centerline radius of 800 ft. A building is located 25 ft. from the centerline. The road is level. Take the coefficient of braking friction as 0.36 and perception-reaction time as 2.5 seconds.
A.Determine the appropriate speed limit on the curve to ensure stopping sight distance
B.Determine the rate of super-elevation (assume that the coefficient of side frictionis0.15)

A horizontal curve forms part of a four-lane highway that has a posted speed limit of 40 mph. The lane width is 12 ft and the radius of the horizontal curve equals 1000 ft at the highway centerline. Determine the minimum distance a large billboard can be placed from the centerline of the inside lane of the curve, without reducing the required stopping sight distance. (Use default values of reaction time and vehicle deceleration).

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....
