Abstract

A road marking has multiple depressions introduced into the road surface, the depressions comprising two lateral longitudinal walls, extending in the longitudinal direction of the road, that transition, proceeding from the road surface, continuously into a bottom region; and the depression being delimited by two transverse walls extending transversely to the longitudinal direction of the road. The road markings have improved utilization properties if provision is made that the longitudinal walls comprise a region convexly curved transversely to the longitudinal direction of the road. The invention further relates to a cutting unit for producing such road markings.
