Research on Highway Video Visibility Detection Technology and Application

Low visibility caused by smog and other factors has a significant impact on highway driving safety and easily lead to traffic accidents. However, the layout density of corresponding traffic meteorological monitoring facilities is far from meeting the requirements for visibility monitoring. This paper proposes a video-based atmospheric visibility detection method, which has been verified in highway. The detection value is relatively close to the detection result using a scattering visibility detector, and meeting the usage requirements of existing monitoring systems to detect atmospheric visibility on highway. The visibility video detection system developed based on this technology provides scientific and effective basis for highway management and control under hazard weather, effectively improving the traffic safety level of highway.
