On the other hand, cant is expressed as the height above low rail and it is expressed in inches or millimeters. So in my opinion, for rail design the only way to go is cant. R. W.

WebOct 15, 2014 · Superelevation is intended to assist the driver by counteracting the lateral acceleration produced by tracking the curve. Superelevation is expressed as a decimal, representing the ratio of the pavement slope to width, ranging from 0 to 0.12 foot/feet. The adopted criteria allow for the use of maximum superelevation rates from 0.04 to 0.12.
