Crest Vertical Curve Length Formula - Civil Engineering

Formula Used:


Lm = ( A×S² ) / ( 200 × (√h1 + √h2)² ) ∀ S<Lm
Lm = 2S − { ( 200 × (√h1 + √h2)² ) / A } ∀ S>Lm


Where,

A - Absolute difference between g2 and g1
S - Sight Distance
Lm - Minimum Curve Length
h1 - Height of drivers eye above roadway surface
h2 - Height of object above roadway surface
Minimum Curve Length
