Superelevating Compound and Reverse Curves
You can use the Superelevation Curve Edit dialog box to establish settings for
compound and reverse curves that you want to superelevate.
Superelevating Compound Curves
In order to superelevate compound curves, the end station of curve 1 must be
the same as the start station of curve 2. When these stations match, all
Transition Out data for curve 1 is ignored and the runout for the Transition In
for curve 2 is ignored. The Transition In data for curve 2 controls the
superelevation transition from curve 1 to curve 2.
To superelevate compound curves
1 From the Cross Sections menu, choose Design Control ä Superelevation
Parameters to display the Superelevation Control dialog box.
2 Select the Superelevation calculations check box to superelevate the cross sections.
3 Click the Edit Data button to display the Superelevation Curve Edit dialog box
for curve 1.
4 In the Curve Edit Information section of the dialog box, edit the superelevation
data.
For more information, see Editing the Superelevation for One Section At a
Time in this chapter.
5 Under Transition In, enter values for Runout, Runoff, and % runoff for curve 1.
6 Under Transition Out, enter 0 for the Runout, Runoff, and % runoff for curve 1.
