A developer is having a single-lane raceway constructed with a 120 mph design speed. A curve on the raceway has a radius of 1200 ft, a central angle of 30 degrees, and PI stationing at 1125+10. If the design coefficient of side friction is 0.20, determine the superelevation required at design speed (do not ignore the normal component of the centripetal force). Also, compute the degree of curve, length of curve, and stationing of the PC and PT. 4.

A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.

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).
