A section of a roadway has a horizontal curve with superelevation of 6% and central angle of 40o. The design speed of the section is 60 mph. There are two lanes on the curve, each 12 ft wide. Determine:

(a) The degree of the curve.

(b) The length of the curve.

(c) The minimum distance of an obstruction from the centerline of the innermost lane.

ou are asked to design a horizontal curve for a two-lane road. The road has 12-ft lanes. Due to expensive excavation, it is determined that a maximum of 35 ft can be cleared from the road’s centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximum superelevation of 0.08 ft/ft. Determine the design speed for this curve (mph)?

A horizontal curve of radius 5620 ft is designed for 60 mph. The roadway is a 4-lane undivided highway with 12-ft lanes. A tree is located on the inside of the curve only 42 ft from the center of the road. Does it pose a stopping sight distance problem for the drivers travelling at the design speed? Show all supporting calculations.

A specification for highway superelevation transition stipulates that the edge profile transition is not to exceed a 1:200 difference from the centerline profile. A right-hand curve is being designed with full superelevation of 8% on a four-lane divided freeway. The lanes are 12ft wide, and the design speed is 70 mph. The normal slope is 1% and the superelevation is to be rotated about the median edge of the running lanes. What is most nearly the minimum length of transition...
