Formula Used:

L_m = ( A×S² ) / ( 200 × (√h₁ + √h₂)² ) ∀ S<L_m L_m = 2S − { ( 200 × (√h₁ + √h₂)² ) / A } ∀ S>L_m Where, A - Absolute difference between g₂ and g₁ S - Sight Distance L_m - Minimum Curve Length h₁ - Height of driver's eye above roadway surface h₂ - Height of object above roadway surface
