Super Elevations Card
5RDGV (GLW 5RDGV
The Super Elevations card of the New Road screen is used to add or
edit super elevations.
A super elevation changes the cross slope of the first segment of a
template in order to bank a curve – the slope of any remaining
segments will remain unadjusted. One super elevation defines a
begin point and an end point where the slope change begins and
where it finishes the transition for one side of a road. Therefore, to
bank a two-lane road, four super elevations would be required – one
at the beginning and one at the end of the curve for each side of the
road.
A super elevation can either hinge at the outer edge of the first
segment, or at the centerline. Hinging at the center results in the
elevation of the outer segments to change. Hinging at the edge
results in the elevation of the centerline changing. Because of this,
Survey Pro will only allow you to hinge on edge for one side of a road.
If the other side is also super elevated, you will be forced
to hinge that side at the center so that an abrupt change
in elevation does not occur at the centerline.
$GG«
: when a super elevation or <End> is selected
from the L or R columns in the Super Elevations card,
this button opens the Add Super Elevation screen, which
allows you to add a super elevation to the same side of
the road that was selected. (Widenings and super
elevations are always sorted in this list by their specified
start stations.)
(GLW
: allows you to edit the selected super elevation in
the Edit Super Elevation screen, which is identical to the
Add Super Elevation screen.

list.
