Detection of vehicles transporting hazardous materials

        Knowing the number and type of vehicles transporting hazardous materials in a tunnel is important for traffic safety. An infrared camera recognizes the hazardous materials placard based on its shape and reads its content. The integrated TIC102 Traffic Information Collector also records the 3D profile for analysis of possible positions of the hazardous material placard. This ensures the read rate is increased considerably and misinterpretations are avoided.
