27. With <End> selected in the Left column, tap
the Add… button again.
28. From the Add Left Super Elevation screen
we will start the transition out of the super
elevation 200 feet from the beginning of the
road so enter 2+00 in the Start Station
field.
29. The super elevation will return to the
original slope after 25 feet so enter 2+25 in
the End Station field.
30. The start slope must be the same as the
slope of the road where it leads into the
super elevation, so leave the Slope 1 field
set to 8.
31. We want the ending slope to be -2% so in the Slope 2 field, enter
-2. Leave the parabolic transition fields set to 0.
32. Be sure the Hinge on field is toggled to Center and then tap
to continue. This will complete the super elevation entries for the
left side of the road.
33. We now need to repeat the above steps for the right side of the
road. Tap <End> in the Right column to select that side of the
road and then tap the Add… button to open the Add Right Super
Elevation screen.
