Length of Summit Curve Less than Sight Distance evaluator uses Length of Curve = (2*Sight Distance)-((sqrt(2*Driver Sight Height)+sqrt(2*The Height of The Obstruction))^2)/Deviation Angle to evaluate the Length of Curve, The Length of Summit Curve Less than Sight Distance formula is defined as twice the sight distance minus the square of the sum of the square roots of two times the driver's eye height and two times the obstruction height, all divided by the deviation angle. Length of Curve is denoted by Ls symbol.
