Road Markings

Contrast (the difference between the pavement marking and the background) is a key characteristic that machine vision (optical cameras) systems associated with ADAS, LDW and Lane Centering use to identify and classify pavement markings. Contrast markings combined with wider marking allows for detection of pavement markings at longer distances relative to narrower, non-contrast markings.

It’s critical that machine vision systems and human drivers can detect pavement markings in all conditions—including when it’s raining and the roads are wet. Pavement markings that deliver continuous wet retroreflectivity can be reliably seen in wet conditions.
