“…The weather-related studies involve a wider range of technologies compared to other categories, mainly because of the relatively higher interdependency with other contributing factors. These include weather monitoring [99][100][101][102], travelling condition [103], modelling and projection of road condition related to the weather [104,105], rainfall estimation using CCTV images [106], impacts of weather on the operation of autonomous vehicles [107], driver warning systems [108,109], public warning systems [110] and enhancing road weather management during extreme weather events [111]. A study of particular interest that has potential for immediate uptake is the approach developed by Lee, Hong [106] employing image processing and machine learning to detect and estimate rainfall from CCTV images in real-time and cluster the regions.…”
