Vertical Curve Calculator Spreadsheet
Introduction & Importance
Vertical curve calculator spreadsheet is an essential tool for engineers and architects to design safe and efficient roadways. It ensures proper vertical alignment, preventing hazardous slopes and improving driver visibility.
How to Use This Calculator
- Enter the length of the curve in feet.
- Enter the desired slope percentage.
- Enter the maximum allowable grade percentage.
- Click ‘Calculate’.
Formula & Methodology
The vertical curve calculator uses the following formula to determine the curve’s length:
L = (S * L) / (G – S)
Where:
- L = Length of the curve (ft)
- S = Slope (%)
- G = Grade (%)
