# Elevation point of vertical curve

Calculate the elevation point of the vertical curve with the given curve length, initial and final grade and the initial elevation.

### Calculator of elevation point on road

#### Formula

y= e_{pvc}+ g_{1}x + [ (g_{2}− g_{1}) ×x² / 2L ]

** Where**,

**y**– elevation of point of vertical tangency**e**– Initial Elevation_{pvc}**g**– Initial grade_{1}**g**– Final grade_{2}**x/L**– Length of the curve
