The gradient is nothing but a slope. And the best way to join 2 gradients using a vertical curve is obviously using a parabolic one.

The rising gradient is change 0.025 and falling 0.013333 beginning tanget elevation is 21.85 and end tangent elevation is 24.18.

Use the parabolic curve (or second degree curve) in vertical curve, because the rate of change of curve of parabola is constant.

Because rate of change of gradient in parabolic curve is constant.
So generally used parabolic type of curve.

All other shapes are 2D. But, to connect two gradients it should be a parabolic which can be drawn in 3D.

Curves are two types they are Summit curve and valley curve.
And the best ideal curve is Summit curve.
And the best ideal curve is Summit curve.

Ideal vertical curve join the two gradient and safe to move any vehicle and angle of inclination.

Vertical curve is parabolic(specification). Length is calculated by means of a circular curve.

Correct answer is circular.
Ideal summit curve is circular. But IRC recommend parabola.
Ideal summit curve is circular. But IRC recommend parabola.
