Answer 2

The correct answer is option (d) Transition curve.

Explanation:

• A curve whose radius varies from infinity to a certain value is called Transition curve.
• Transition curve refers to a curve in plan which is provided to change the horizontal alignment from straight to circular curve gradually means the radius of transition curve varies between infinity to R or R to infinity.
• The Purpose of Transition curves is to provide Super Elevation in a gradual manner and to minimize the radius from infinity at a straight junction to a radius R at curved junction gradually.
