If the vertical curve is negative what is curve?

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

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

How it will be parabolic?

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

A rising gradient of 1 in 40 is to be connected with a falling gradient of 1 in 75 by means of a vertical equal tangent parabolic curve 400 m in length. The reduce level at the intersection point of the tangent is 26.850.
Calculate:
(1) The rate of change of grade.
(2) The reduced levels at the beginning and end tangent points.

The main design criteria in a vertical curve is headlight sight distance. So I think it may be circular as the sight distance available at each point is same.

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