Calculate the minimum curve length required for the vertical curve. This calculator is mainly used while designing the roadways in which the sight distance can be greater or less than the curve length.
Calculator of Crest Vertical Curve Length on Roadways
Lm = ( A×S² ) / ( 200 × (√h1 + √h2)² ) ∀ SLm
- A – Absolute difference between g2 and g1
- S – Sight Distance
- Lm – Minimum Curve Length
- h1 – Height of driver’s eye above roadway surface
- h2 – Height of object above roadway surface
