Description
Cross fall (also referred to as cross slope, camber or cant) is the slope of the road surface measured laterally from the outside edge (or kerb) toward the median line. Cross fall is positive if the slope rises away from the outside edge or kerb. Cross fall is negative if the slope falls away from the outside edge.
It is normal for the middle of straight or gently curving roads to be slightly higher than the edges so that rainwater will flow off the sides of the road. Such roads have positive cross fall on either side of the median line
This variable is measured per lane at the reference point and the unit is [%].
