Changing the Superelevation Settings
When you change the superelevation settings, you apply a set of instructions
going into a curve and another set for coming out of a curve.
To change the superelevation settings
1 From the Cross Sections menu, choose Design Control ä Superelevation
Parameters to display the Superelevation Control dialog box.
2 Click Settings from the top group of buttons to display the Superelevation
Curve Settings dialog box.
3 Under Curve Edit, enter the following settings:

Since this dialog box is used for setting information, this value is always zero
(0) and cannot be edited.
n

E value: The value you enter in this edit box is the maximum crossfall value
for the fully superelevated template.

Direction: This popup list displays the directions for the curve. The direction
of curvature can be either right or left, and is based on station progression.
The direction of curvature should not be edited unless curve information is
inserted manually.

Rollover: To apply rollover to the template, select the Rollover check box
and enter the rollover percent grade in decimal form. For example, type a six
percent grade as .06. This grade is the maximum difference between the
grades of fully superelevated road surface and the shoulder. The shoulder is
represented by the rollover points you select when you edit the template to
define the superelevation regions.
