The Superelevation allow us to set how much banking to apply to curves in the horizontal alignment to help offset centrifugal force. It helps to identify how the road will make the transition from normal crown to a fully banked curve and back again. Pavement slopes are initially defined in the template. Superelevation is applied after the corridor is defined and the template drops have been assigned.

The result of superelevation are graphic superelevation lanes with cross slope attributes stored in a DGN file. The superelevation data can be in its own DGN file or can be drawn into any of the other project DGN files with geometry, corridor, etcetera. This file can be referenced to a corridor model and associated, so the superelevation transitions are incorporated into the corridor model.

OpenRoads Designer provides user to create superelevation sections, superelevation lanes, assign superelevation to corridor, add template to calculate superelevation etc.
