What is the purpose of superelevation in highway design?

Step 1: Understand that when a vehicle goes around a curve, it experiences a force pushing it outward, called centrifugal force.
Step 2: Realize that this force can make it hard for vehicles to stay on the road, especially at higher speeds.
Step 3: Learn that superelevation is the banking of the road at a curve, meaning the road is tilted to one side.
Step 4: Know that this tilt helps counteract the centrifugal force, allowing vehicles to maintain their speed safely without sliding off the road.
Step 5: Conclude that the purpose of superelevation is to improve safety and comfort for drivers when navigating curves.
