Extend the sheet to calculate superelevation runoff lengths and pavement cross‑section elevations at stations along the curve. With Excel’s built‑in functions, you can also generate banking diagrams automatically.
= (B2^2) / (127 * C2) - E2 (adopted e):
[ e_required = \fracV^2127 \cdot R - f ] superelevation calculation excel sheet
= IF( F2 <= D2, "OK", "e_max insufficient – increase radius or reduce speed" ) (minimum radius for given speed and e_max): Extend the sheet to calculate superelevation runoff lengths
Please wait... it will take a second!
