A developer is having a single-lane raceway constructed with a 180 km/h design speed. A curve on the raceway has a radius of 320

m, a central angle of 30 degrees, and PI stationing at 11 511.200. If the design coefficient of side friction is 0.20, determine the superelevation at the design speed (Hint: Consider normal component of the centripetal force). Also, compute the length of curve and stationing of the PC and PT.
