Setting Up Superelevation

Before calculating superelevation data, you need to ensure that required settings and styles are specified correctly.

Specify a design speed		Specify a design speed in the alignment properties. A design speed is necessary to calculate superelevation.
Specify Superelevation label defaults		Review the superelevation critical point label options on the Abbreviations tab in the Drawing Settings.
Verify alignment feature settings		Review the alignment feature settings for Superelevation Options and Dynamic Alignment Highlight Options.
Verify default label abbreviations		Review the default label abbreviations for geometry points and superelevation critical points.
Customize criteria files		Customize the criteria files using the Design Criteria Editor. Superelevation is calculated based on these files.
Review Profile View band properties		Specify the Profile View band properties for superelevation data.
Create the alignment		Create an alignment to use for superelevation calculations.
Optionally, add user-defined curves		Add user-defined curves from the Superelevation Curve Manager. Add curves for situations where a curve is not automatically created by the program, for example where an alignment has two compound spirals or a compound spiral in between spirals. Curves can be added after calculating superelevation data but you have to re-calculate the superelevation.
