WebSep 27, 2015 · Psychological widening is therefore important in pavements with more than one lane. An empirical formula has been recommended byt IRC for deciding the additional psychological widening ‘Wps’ which is dependent on the design speed, V of the vehicle and the radius. R of the curve. The psychological widening is given by the formula: Wps 7. 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. copper country veterinary clinic houghton https://fourseasonsoflove.com
