Common Mistakes When Using “superelevation”
- Misspelling as 'super elevation' (two words).
- Confusing 'superelevation' (for curves) with 'grade' or 'gradient' (for slope in the direction of travel).
- Pronouncing it with primary stress on the first syllable (SUper...) instead of on '-va-' ( ...eleVA-tion).
FAQ
Frequently Asked Questions
No. Camber (or crossfall) is the slight slope across a straight road for drainage. Superelevation is the intentional banking on a curve for stability against centrifugal force.
Yes, 'negative superelevation' (or adverse camber) can occur, typically on low-speed curves or to discourage excessive speed, where the outer edge is lower than the inner edge.
It is commonly expressed as a percentage (rise over run), a ratio (e.g., 1:40), or an angle in degrees.
Yes, it is a critical concept in railway track design, where it is often called 'cant'. It helps trains navigate curves smoothly and safely.
The banking or cant of a road or railway track on a curve, designed to counteract the effects of centrifugal force and allow vehicles to traverse the curve at higher speeds with greater safety and comfort.
Superelevation is usually technical / formal in register.
Superelevation: in British English it is pronounced /ˌsuːpərˌɛlɪˈveɪʃ(ə)n/, and in American English it is pronounced /ˌsuːpərˌɛləˈveɪʃ(ə)n/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a SUPER highway that is ELEVATED on one side of a curve to make your ride super smooth.
Conceptual Metaphor
A CURVED PATH IS A TILTED SURFACE. The tilt (superelevation) compensates for the sideways pull (centrifugal force).
