Ideal vertical curve is circular but vertical curve provided in field is square parabola for summit curves and cubic parabola for valley curves.

Ideal vertical curve is circular if sight distance available throughout the length of curve is constant it possible only in case of Joining one Gradient. In this case, two gradient are Joint by curve therefore sight distance is not constant throughout the length of curve so we provide Simple Parabolic curve.

Correct answer is circular.

Ideal summit curve is circular. But IRC recommend parabola.

In highway engineering, we deal with two type of vertical curves summit and valley.

IRC CLEARLY have defined the ideal vertical curves for summit it is circular and for valley it is cubic.
