Creating the Roadway Superelevation with Templates and Cross Sections
365
To import superelevation into a profile
1 Define a transition point at the same location as the superelevation region
point.
2 From the Cross Sections menu, choose Design Control ä Superelevation
Parameters to display the Superelevation Control dialog box.
3 Under Superelevation Toggles, clear the Superelevation calculations check box.
This allows the outer edge of the superelevation region to be completely
controlled by the transition profile elevations.
4 Click OK to display the Save Status dialog box.
5 Click Yes. If there are errors, the Section Processing Status dialog box is
displayed.
6 Click OK until you exit the Superelevation Control dialog box.
7 From the Cross Sections menu, choose Ditch/Transition ä Import Profile.
The following prompt is displayed:
Profile to draw [Left/Right]:
8 Enter L for Left.
The following prompt is displayed:
Left profile to draw [Ditch/Super/1/2/3/4/5/6/7/8]:
9 Enter S for Super.
If you specify S for Superelevation, and if you specified Left, the following
prompt displays for the left side:
Profile layer to use (L1/L2/L3/L4/L5/L6/L7/L8):
10 Specify the transition layer to use.
These layer names represent the transition regions you define on the template
with the Edit Template command. Because the superelevation control point and
the transition control point have to be in the same location on the template in
order for this to work, you must specify the number of the transition region you
are using for this purpose.
When you import a ditch or transition into the plan view, you can also define it
as an alignment if required since the transitions and ditches are imported as line
entities. This step isnt necessary if you imported the lines for viewing or
plotting purposes only.
You can make edits to these lines before defining the alignment or you can go
directly to defining and alignment.
