WebAug 6, 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.
