The modern, easy-to-use retroreflectometer
LTL-M, the DELTA mobile retroreflectometer for measuring night visibility (RL) of pavement markings at traffic speed, is a new generation of mobile systems – and has already achieved a significant market penetration. The system solution outperforms other similar systems by offering better and more sophisticated solutions to mobile retroreflective measurements, including night visibility RL, daylight contrast, marking width, road stud (RRPMs) presence, etc.
Retroreflectivity measurements can be acquired at normal traffic speed, and during day or night at the user’s preference, hence avoiding dangerous incidents, where an operator must make handheld measurements in a busy road. Over 3,000 kilometers of road can be measured in a normal working week.
Employing advanced camera-based techniques and real-time digital image processing ensure accurate measurement results under all driving conditions. Embedded features such as compensation of vehicle bouncing, vertical lifting, tilting, as well as handling of difficult measurement conditions for e.g. very curved roads, large variations in stripe profile height, etc. have positioned LTL-M at top in mobile systems and certainly ahead of the first generation of systems as seen from other suppliers.
