How to Calculate Setback Distance where Ls is Smaller than Lc?
Setback Distance where Ls is Smaller than Lc calculator uses Setback Distance = Radius for Transition Curve-Radius for Transition Curve*cos(Angle subtended by Radius of Curve for Single Lane/2) to calculate the Setback Distance, The Setback Distance where Ls is Smaller than Lc formula is defined as the distance required from the centerline of a horizontal curve to an obstruction on the inner side of the curve to provide adequate sight distance at a horizontal curve. Setback Distance is denoted by m symbol.
How to calculate Setback Distance where Ls is Smaller than Lc using this online calculator? To use this online calculator for Setback Distance where Ls is Smaller than Lc, enter Radius for Transition Curve (R_{trans}) & Angle subtended by Radius of Curve for Single Lane (α_{1}) and hit the calculate button. Here is how the Setback Distance where Ls is Smaller than Lc calculation can be explained with given input values -> 10.22225 = 300-300*cos(1.5707963267946/2).
