SAG Vertical Curve Length Calculation

SAG vertical curves are curves similar to the shape of a parabola. It is practically used to design the roadways to allow the vehicles head lights to illuminate on the roadway surface. The head lights is assumed to have a 1-degree upward divergence from the longitudinal axis of a vehicle. Slight height is the important parameter used to estimate the length of the curve. In SAG vertical curve length calculation, length is the major measurement.
