For horizontal alignment, ideal curve is a spiral.
And for vertical alignment ideal curve is a cubic parabola.
Here, the summit curve is vertical alignment so the parabola is the right one.

Ideal shape of summit curve is circular.

But Square parabola is the best shape of the summit curve due to good riding qualities, simplicity of calculation, and uniform rate of change of grade.
