Pivot at Inside of Curve - Maintain Median Shape (Superelevation on Divided Planar Roads)

The following illustration describes the Inside of Curve pivot method for a divided planar roadway.

Maintain Median Shape means when superelevation is applied, the median will raise to accommodate the superelevation. This option maintains the median shape, and the pivot points raise or lower.
