Add / Edit Super Elevation Screen
( or ) ( or
)
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.
/ : 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 elevation is entered to change the slope back
again. For example, a curve will typically require two
super elevations for each side of the road: one at the
beginning of the curve and one at the end.
Slope 1
/
2
: is the starting and ending slopes of the road,
respectively. The starting slope must match the current slope of the
road at that station.
Parabolic Transition 1
/
2
: is the length of the vertical curve that will
lead in and out of the super elevation, respectively. Parabolic
transitions are optional parts of a super elevation and result in a
smoother change going into and coming out of a super elevation,
similar to how a spiral curve is used with a horizontal curve.
