When you click OK, your new entry will be in the list.
The Edit box leads to the same entry dialog as Add. Remove will provide a warning and then delete the highlighted
offset and elevation. Up and Down should not be used unless a file conversion led to out-of-order listing of offsets and
elevations. When you click OK from the station edit dialog, you can save the revised cross section file back in the
section list dialog.
Input-Edit Superelevation
Roads can contain one or more curves, and each curve can have its own superelevation data. This data includes start
station for super transition, station for full super, percent of full super, station for end full super, and station for ending
the super transition back to normal crown. In FAST Survey, each superelevation data set for each curve would be
entered as a “line” of superelevation data in the “.sup” file.
If we had two curves, both with superelevation, then we would do two Adds using this dialog. Let’s say, for simplicity,
that we have a road with a 2% “normal crown” which has one curve to the left followed by one curve to the right, with
the following information:
Curve 1 Curve 2
Start Super Pivot Sta: 100 Sta: 2200
Full Super Sta: 600 Sta: 2500
Full Super %: 3% Left 4% Right
End Super: Sta: 1400 Sta: 3500
End Super Pivot: Sta: 1900 Sta: 3800
The first curve to the left goes through three stages as it pivots into full super: (1) the right side pivots to “flat”, (2) the
