Retroreflectometer measures road markings at traffic speed
Delta, a globally leading supplier of retroreflectometers for road markings and traffic signs, will use Intertraffic Amsterdam 2014 to highlight its most recent development - the LTL-M system, a state-of-the-art retroreflectometer for measuring retroreflection of road markings at traffic speed.
The system is based on patented technology making use of a digital camera and real time digital image processing. A main advantage of the LTL-M is its ability to measure accurately under all driving conditions and in line with handheld retroreflectometers. In addition, as the company points out, the LTL-M is easy to mount on any vehicle, simple to calibrate, and easy to operate. Measurement results are presented as figures, graphs and displayed on Google Earth for easy overview and data presentation.
Delta will also be showcasing its traditional line of handheld retroreflectometers, including the LTL-X, LTL-XL and RetroSign GR1 & GR3. These instruments provide spot measurement of retroreflection of road markings and traffic signs. Results are presented as figures or displayed on Google Earth for easy overview and data presentation.
An important feature of Delta instruments is that they use the latest technology and are robust, intuitive and very easy to operate. Importantly, a fast and simple calibration in the morning, before starting the measurement programme, means the instrument can be used all day without recalibration.
As the company points out, all its instruments comply with international standards and its calibration standards are calibrated at Delta’s Danak accredited calibration laboratory and is traceable in accordance with standards issued by PTB (Physikalisch-Technische Bundesanstalt, Germany) and NIST (National Institute of Standards and Technology, USA).
