The Delta LTL-M is a new generation mobile retroreflective measuring system used for pavement marking measurements at traffic speed 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. The system employs advanced camera-based techniques and real-time digital image processing to ensure accurate measurement results under all driving conditions. It is also embedded with 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.
