Transition curves are introduced at either end of a circular curve, to...
The correct answer is option 'B', Transition curves are introduced at either end of a circular curve in a roadway or railway track to provide a smooth transition between the straight section of the roadway or track and the circular curve. Transition curves are designed to provide a gradual increase of superelevation (the difference in elevation between the outer and inner edges of a roadway or track) from zero at the tangent point (the point at which the straight section of the roadway or track meets the circular curve) to the specified amount at the junction of the transition curve with the main curve. This gradual increase of superelevation helps to improve the safety of vehicles traveling around the curve by reducing the likelihood of vehicles tipping over or losing traction.

Introduction to Transition Curves:
Transition curves are introduced in a highway or railway alignment, where the curvature or the superelevation changes suddenly, which may cause discomfort or even danger to the passengers. These curves are also called easement curves, which allow the vehicles to enter or leave the circular curve gradually, without any sudden jerk or discomfort.
Purpose of Transition Curves:
The purpose of transition curves is to provide a gradual change in curvature or superelevation, which allows the vehicles to traverse the curve comfortably and safely. It also helps in reducing the wear and tear of the vehicles and the tracks, as sudden changes in curvature or superelevation may cause excessive wear and tear.
Types of Transition Curves:
There are different types of transition curves, such as:
1. Spiral Transition Curve
2. Cubic Parabolic Transition Curve
3. Clothoid Transition Curve
Out of these, the most commonly used transition curve is the clothoid transition curve, which provides a gradual change in curvature and superelevation.
Gradual Increase of Superelevation:
The correct option for the purpose of introducing transition curves is "Gradual increase of super-elevation from zero at the tangent point to the specified amount at the junction of the transition curve with main curve." This means that the transition curve is introduced to provide a gradual increase in superelevation from zero at the tangent point to the specified amount at the junction of the transition curve with the main curve.
The superelevation is the banking of the curve, which allows the vehicles to travel at a higher speed without any lateral forces acting on them. The transition curve provides a smooth transition from the tangent to the circular curve, by gradually increasing the superelevation. This allows the vehicles to enter or leave the curve comfortably and safely, without any sudden jerk or discomfort.
Conclusion:
Transition curves are an essential part of highway and railway alignments, which provide a smooth transition from the tangent to the circular curve. The most commonly used transition curve is the clothoid transition curve, which provides a gradual change in curvature and superelevation. The purpose of introducing transition curves is to provide a gradual increase in superelevation from zero at the tangent point to the specified amount at the junction of the transition curve with the main curve.
