superelevation

[¦sü·pər‚el·ə′vā·shən]
(ordnance)
An added positive angle in antiaircraft gunnery that compensates for the fall of the projectile during the time of flight due to the pull of gravity.
The angle the gun or launcher much be elevated above the gun-target line.

At the site scale where landscape architects are primarily delegated with road layouts and their calculations, such as parks and residential projects, the use of transitional curves for low design speeds are not essential if properly designed circular curves with superelevation and adequate lane widths are employed.
Roadway superelevation will not typically exceed 6 or 7 degrees [The Green Book, 1990].
The article looks at geometrical track parameter superelevation the determination of which may vary in different countries; however, the essence remains the same--superelevation is calculated in respect of rated track parameters: track radius and average and/or maximum permissible rated train speed.
According to his new model, it's far more likely that the highest flow marks reflect superelevation of a 3-to-10-m-deep flow of snow that raced around and up the side of the curve during an avalanche lasting about 23 seconds.
The Scurve failed to meet current design criteria for alignment and superelevation.
He has already completed one on superelevation (the banking of highway curves) and is currently working on a tutorial on basic surveying skills.
The project will correct existing geometric deficiencies, the substandard mainline curve and negative superelevation, which cause crashes.
Engineers settled on maximum 3-percent grades and 6-degree curvature, with substantial superelevation, or banking, on curves.
The authors noted measurement limitations, such as superelevation and grade, would require terrestrial survey instruments [15].
Furthermore, there are also models in which, in addition to the geometric characteristics of the horizontal alignment, the cross-sectional characteristics (lane width (LW), shoulder width (SW) or superelevation (e)) are taken into account (Lamm, Choueiri 1987; SETRA 1986).
The heavier of the two also features dual axis stabilisation, manual back-up, automatic target tracking, and superelevation allowing to decouple the optical pod from the weapon.
