Audio Tactile Profiled Markings

 

Audio Tactile Profiled (ATP) markings (also known as rumble strips) are a combination of painted line marking and raised profile thermoplastic ribs that provide an audible (sound) and sensory (vibration) warning to alert drivers of a possible lane departure.

 

ATP markings can be an effective measure to reduce run-off-road and head-on crashes and improving road safety. Research indicates that throughout New Zealand where ATP markings have been installed, casualty crashes have reduced by up to 39%.
