Chapter 6 Viewing and Editing Roads in Section View

You can choose one of five superelevation methods for different
situations. The following dialog box explains the five methods.
The following illustration shows superelevation method A. The cross
sections at the bottom of the illustration show cross sections of the
crown at even distances along the profile.
The illustration shows the rate of change in the superelevation is
constant between section A and C. The rate of change is constant
because the distance between B and C is equal to the distance between
A and B (the runout distance). Depending on the design criteria, there
may be a change in the rate of change in superelevation at section C.
Key Concepts
■
To apply superelevation to cross sections, you need to use the Edit
Template command to place superelevation control points on the
roadway surface template.
