Audio Tactile Line Markings (ATLMs) (also called profiled lines or rumble strips) can reduce the likelihood of crashes by up to 45%.
Black ATLMs have even more advantages as:
???? You can create continuous ATLM on both broken and unbroken centrelines (no gaps).
???? You only need one run for barrier and semi barrier lines.
???? Black costs less as you don’t need to use high cost white beads
???? You can offset on edge and centrelines to extend the life of the treatment because it doesn’t get hit as often. This in turn reduces noise to nearby residents.
