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,
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.
Add… : 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.)
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.
Check… : checks the road for errors and displays the results in the
Roads Report screen, described on Page R-405.
