Special forecasting technology has been developed using Artificial Intelligence (AI) to transform the data to predict black ice occurrence on roads and just how slippery the road will be. Based on this information, the system categorizes road conditions into three levels: observe, caution, and alert, providing drivers with notifications one hour in advance. In cases where AI predicts black ice, an automatic salt-spreading project is also in development to ensure efficient and timely spreading. The forecasting technology is expected to be integrated into the navigation systems of most vehicles used by Koreans to ensure drivers are aware of dangerous road conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-aca43cd elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"aca43cd\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-33be952\" data-id=\"33be952\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-43e0d25 elementor-widget elementor-widget-text-editor\" data-id=\"43e0d25\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Ensuring Safety Throughout Korea<\/h3><p>The adoption of advanced Road Weather Information Systems (RWIS) represents a crucial step in enhancing safety along Korea&#8217;s mountainous highways.
