How to Calculate Setback Distance for Multi Lane Road where Ls is greater than Lc?
Setback Distance for Multi Lane Road where Ls is greater than Lc calculator uses Setback Distance = Radius for Transition Curve-(Radius for Transition Curve-Center Distance between Road and Inner Lane)*cos(Angle subtended by Radius of Curve for Single Lane/2)+((Sight Distance-Length of Transition Curve)/2)*sin(Angle subtended by Radius of Curve for Single Lane/2) to calculate the Setback Distance, The Setback Distance for Multi Lane Road where Ls is greater than Lc formula is defined as clearance distance is 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 for Multi Lane Road where Ls is greater than Lc using this online calculator? To use this online calculator for Setback Distance for Multi Lane Road where Ls is greater than Lc, enter Radius for Transition Curve (R_{trans}), Center Distance between Road and Inner Lane (d), Angle subtended by Radius of Curve for Single Lane (α_{1}), Sight Distance (S) & Length of Transition Curve (L_{c}) and hit the calculate button. Here is how the Setback Distance for Multi Lane Road where Ls is greater than Lc calculation can be explained with given input values -> 26.33553 = 300-(300-1.2)*cos(1.5707963267946/2)+((3.56-180)/2)*sin(1.5707963267946/2).
