Online civil calculator helps you to calculate elevation of a point on the curve. The vertical alignment of a transportation facility consists of tangent grades (straight lines in the vertical plane) and vertical curves.
Formula:
y = y0 + g1x + [(rx2) / 2]
where,y0 - elevation of the beginning of the vertical curve (BVC)
g1 - grade just prior to the curve
x - horizontal distance from the BVC to the point on the curve
r - rate of change of grade
y - elevation of a point on the curve
