Superelevation - Purpose - Design & How To Calculate It?

The highway plays a vital role in the country’s economic growth by connecting people and transporting goods.
We may unaware of many implementations that the experts used for our safety while we are on the road.
One of them is Super Elevation.
The term superelevation is denoted in both road and railway transport, especially in curved pathways.
Superelevation is the transverse slope along the width of the road provided by rising from the outer edge of the road to the inner edge, throughout the length of the horizontal curve.
It is provided to facilitate the safe passage of the vehicle in a horizontal curve.
Superelevation reduces the effect of centrifugal force on the running wheels.
If superelevation is not provided the entire centripetal force is produced by the friction between the vehicle’s tires and the roadway,
thus resulting in reducing the speed of a vehicle.
