Samenvatting One of the most important meteorological parameters affecting road users and their safety is fog. This study develops the hazardous fog index which quantifies the degree of danger depending on frequency of fog, visibility and its duration. We applied this index to Korea with 3 years weather station data in order to investigate the distribution of the hazardous fog and found that these application results were useful for identifying the dangerous area due to hazardous fog. Also we prove that these application results are more realistic and practical than the existing fog area index. Hazardous Fog Index may be useful tool to provide the nationwide ranks of dangerous fog prone areas to the decision makers and the Index may be applied to the examination of fog-related black spots along all the major roads and expressways in Korea.
