To create a super-elevation in road design, follow these steps: first, determine the appropriate degree of super-elevation based on the road's design speed and curve radius. Next, calculate the required cross-slope by using the formula that considers speed, radius, and gravitational forces. Then, design the road cross-section to incorporate the super-elevation, ensuring proper drainage. Finally, implement the construction, ensuring that the transition into the super-elevated section is smooth for vehicles.
The term negative superelevation is when the driving surface of a vehicle or device has sloped or has become askew from its center or its horizontal curve.

Neither. Steps are taken, not followed. Use The following steps must be taken.
Superelevation is the banking of a road or railway curve, where the outer edge is raised higher than the inner edge. This design helps counteract the lateral acceleration experienced by vehicles when navigating a curve, improving safety and stability. By tilting the roadway, superelevation enables vehicles to maintain higher speeds while reducing the risk of skidding or overturning. The degree of superelevation is typically determined by factors such as curve radius, speed limits, and road conditions.

Superelevation in road construction refers to the banking of a roadway at a curve to counteract the lateral acceleration experienced by vehicles. This design feature helps vehicles maintain traction and stability while navigating turns, reducing the risk of skidding. The degree of superelevation is determined by factors such as the curve's radius, design speed, and road conditions. Proper superelevation improves safety and enhances the overall driving experience.
