Add Super Elevations
19. Tap the Super Elevations tab where we will
insert a super elevation at the beginning
and end of a curve for the left and right
sides of the road.
20. With <End> selected in the Left column,
tap the Add… button. This opens the Add
Left Super Elevation screen, which allows
you to add a super elevation to the left side
of the road.
21. We will start the super elevation 100 feet
from the beginning of the road so enter
1+00 in the Start Station field.
22. The super elevation will be at the final
slope after 25 feet so enter 1+25 in the

End Station field.
23. The start slope must be the same as the
slope of the first segment of the template
that leads into the super elevation, so leave
the Slope 1 field set to -2.
24. We want the ending slope to be 8% so in the Slope 2 field, enter 8
for simplicity, we will not use parabolic transitions so leave those
fields set to 0.
25. Most super elevations hinge at center so be sure the Hinge on
field is toggled to Center and then tap to continue. This will
complete the super elevation for the beginning of the curve on the
left side of the road.
26. We now need to add a super elevation at the end of the curve on
the left side of the road to change the slope back to -2%.
