    1 Number of calculations
    r = \frac{{g_2 - g_1}}{{L}}

    The variables used in the formula are:

    r – Rate of change of grade

    g1 – Initial roadway grade

    g2 – Final roadway grade

    L – Length of the curve

    Calculating the rate of change of grade for roadways is made simpler and more accessible with online, free vertical curve calculators.
