Utilize our complimentary online tool to compute the length of a crest vertical curve. Input the following parameters: Distance, Initial Grade, Final Grade, Height.

This calculator calculates the essential length of a crest vertical curve, which is particularly valuable in roadway design. It addresses situations where the line of sight may surpass or fall short of the curve’s length requirement.

## Crest Vertical Curve Length formula

The variables used in the formula are:

A – Absolute difference between g_{2} and g_{1}

S – Sight Distance

L_{m} – Minimum Curve Length

h_{1} – Height of driver’s eye above roadway surface

h_{2} – Height of object above roadway surface

The calculation of a convex-shaped vertical curve is made simpler with the help of the Crest Vertical Curve Length Calculator.
