Vertical Curve Calculator
Calculate Vertical Curve Parameters
About Vertical Curve Calculator
This calculator determines vertical curve parameters for road design and surveying, including curve length, elevation, and grade changes for highway and road construction.
Curve Types:
- Sag Curve: Concave upward, used for grade changes from positive to negative
- Crest Curve: Concave downward, used for grade changes from negative to positive
- Minimum Length: Based on design speed and algebraic difference in grades
- Stopping Sight Distance: Critical factor for curve design
