WebAlignment and Superelevation D-2 Revised November, 2011 circular section is the point of curvature (PC). The point at which the alignment changes from a circular to a tangent section is the point of tangency (PT). The point at which two adjoining circular curves turning in the same direction meet is the point of compound curvature (PCC). Web6 aug. 2024 · The formula for calculating is given below : Where, e = Super elevation. f =coefficient of friction. v = speed in kmph. R = Radius of the curve in metre. Putting all the values in the formula we get, ∴ e = 0.201 – 0.15 = 0.051 per meter of carriage way. ∴ Super elevation = 0.051 * 7 = 0.357 m or 35.7 cm above the inner edge of the road.
