A developer is having a single-lane raceway constructed with a 320 km/h design speed. A curve on the raceway has a radius of 1320 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 required at the design speed? Make sure you use the exact equation for R and not the approximate equation for R. Include a discussion (a short paragraph) of why this important. Also, compute the length of curve and stationing of the PC and PT.
