Tutorial: Applying Superelevation to an Alignment

In this tutorial, you will calculate superelevation for alignment curves, create
a superelevation view to display the superelevation data, and edit the
superelevation data both graphically and in a tabular format.
The superelevation feature enables you to apply your local roadway design
standards to automatically calculate roadway cross slopes around curves.
BEST PRACTICE Superelevation should be calculated before the corridor model
is built along the alignment.
For more information, see Understanding Superelevation.

Exercise 1: Calculating Superelevation for an Alignment

In this exercise, you will calculate superelevation for all the curves in an
alignment.
For more information, see Calculating Superelevation Data Using the Wizard.
To calculate superelevation for a curve
1 Open Align-Superelevation-1.dwg, which is located in the
folder
2 Select the alignment.
3 Click Alignment tab
drop-down
A dialog box indicates that the alignment does not contain superelevation
data.
4 Click Calculate Superelevation Now.
In the Create Superelevation dialog box, the Roadway Type page contains
options for how to apply superelevation to various types of roadways.
Conceptual graphics illustrate the point about which each lane will pivot.
5 Select Undivided Crowned, Pivot Center.
