Transition Curve Tangent Distance – Mathematically Calculated Curve

Transition curves are of great use as they provide better visibility to driver, calculate accurate transition curve tangent distance by using this free calculator.

Curve Tangent Distance

To calculate Transition Curve Tangent Distance:

  • Length of spiral from tangent to any point (L)

  • Length of spiral (Ls)

  • Radius of Simple Curve (R)

  •  

Results:

  • Tangent distance to any point on the spiral (Y)
