Transcribed Image Text:A single-lane racetrack is being constructed with a 150 mph design speed. A curve on this
track has a radius of 4500 ft, central angle of 30 degrees, and a PI located at station 150+40.
If the coefficient of side friction is 0.3, what superelevation is required for safe vehicle travel
at the design speed? Also, determine the length of the curve and station of the PC and PT.
