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 = epvc + g1x + [ (g2 − g1) ×x² / 2L ]

Where,

  • y – elevation of point of vertical tangency
  • epvc – Initial Elevation
  • g1 – Initial grade
  • g2 – Final grade
  • x/L – Length of the curve
