Both the Laserlux and RetroTek systems can be used at normal road speeds, eliminating the need for road closures/traffic management.
Independent tests have verified that the RetroTek-D accurately measures in day or night the night visibility RL (coefficient of retroreflected luminance) of pavement line/striping markings to CEN En 1426 & ASTM E 1710 & as accurate as hand held retroreflectometers. The system also counts the presence and absence of Pavement Markers (RPMs)/ road studs and centre median barrier reflectors. RetroTek-D uniquely measures the retroreflectivity (RL) of both right and left longitudinal lines (edge and centre lines) and centre lane marking/symbols. This is not possible for side mounted systems without road closure/traffic management & multiple survey passes.
Both systems can accurately measure the daylight contrast ratio between the road surface and the road markings. The RetroTek-D has built-in automatic compensation for bright sunlight, shadows, road glare and vehicle bouncing from uneven road surfaces and driving behaviours (accelerating/braking).
Both systems use GPS to accurately record the exact locations where measurements have been taken, and where road markings have not met retroreflectivity requirements. This allows road maintenance authorities to efficiently plan reparation & maintenance efforts. This data is stored automatically.
Both the Laserlux G7 and RetroTek-D can be transferred to any vehicle due to the non-permanent nature of their fitting. The Laserlux can stick to the side of any vehicle whereas the RetroTek can utilise the tow hitch of vehicles with a front towing point.
