Black ice detection for automatic traffic guidance systems

In order to increase safety at safety-relevant points, non-contact infrared pyrometers are installed at pedestrian crossings. Thanks to the large measurement distance, the thermoMETER from Micro-Epsilon records the ground temperature from a safe distance and provides high measurement accuracy. When icing starts, the pyrometers send a signal to the traffic control system, which converts it to an ice warning or to speed regulation on traffic signs. In addition to pedestrian crossings, the pyrometers are also used at motorway and highway bridges or road sections where black ice frequently occurs.
