the banking or sloping of a road curve to enable vehicles to maintain a speed consistant with the overall speed of the roadway. The banked ends of racing tracks represent an exaggerated superelevation.
Curved track usually has the outer rail raised slightly above the inner one (superelevated) to tilt the centre of gravity of the train inwards. This reduces the lateral forces experienced by passengers and improves the stability of the train when passing through curves at speed. See Cant (Superelevation)
The continuous transverse slope normally given to the carriageway at horizontal curves.
the rise of the outer edge over the inner edge of the road surface at curves, expressed in feet per foot, for the expressed purpose of counteracting centrifugal force
