Run<strong>of</strong>f<br />
For appearance and comfort, the length <strong>of</strong><br />
superelevation run<strong>of</strong>f should be based on a<br />
maximum acceptable difference between<br />
the longitudinal grades <strong>of</strong> the axis <strong>of</strong><br />
rotation and the edge <strong>of</strong> pavement.<br />
Proper run<strong>of</strong>f design can be attained<br />
through the exclusive use <strong>of</strong> the maximum<br />
relative gradient.
