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 driver's eye above roadway surface h2 - Height of object above roadway surface Minimum Curve Length
