Super Elevations Card
[Roads] [Edit Roads] ([New…] or [Edit…]) [Super Elevations]
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, the software 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.
[Add…]: when a super elevation or
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.)
[Edit]: allows you to edit the selected super elevation in the Edit Super Elevation screen, which is identical to the Add
Super Elevation screen.
[Remove]: removes the selected super elevation from the list.

The Add / Edit Super Elevation screen allows you to add a super elevation to the road or edit an existing super
elevation.
Start Station: is the location of the beginning of the super elevation on the alignment.
[Length] / [End Station]: is the length of the super elevation measured from the Start Station, or it is the end station,
depending on how the button is toggled.
Note: Keep in mind that the slope at the end of a super elevation will continue down the road unless another super
