Driving an AI-powered future, we use machine learning translation in this website.


Our road portfolio covers the latest innovations for testing the visibility of road markings, traffic signs and airport markings. As we head into an age of autonomous vehicles that rely on well maintained road markings, it’s become more critical than ever to establish greater uniformity and higher standards. Measure the retroreflectivity of road markings, studs, signs and other reflective materials accurately and efficiently with Zehntner Retroreflectometers. Intelligent mapping software, full traceability, and real-time data sharing.
