An Introduction to a Risk Assessment Method of Traffic Meteorological Disaster on Highway in China

A risk assessment method of traffic meteorological disasters on Highway was introduced in this paper. The hazard of meteorological factors, such as low visibility, heavy rainfall, gale and frozen rain and snow, were analyzed by applying Fuzzy mathematical and Grey correlation, and were compared with subjective method of AHP. Simultaneously, the risk of traffic meteorological disaster on highway was assessed by using the sensitivities, exposure, vulnerability and capacity of disaster prevention and reduction. Based on GIS technology, the area was divided into the basic grid units of 10 km×10 km over China. The each index was processed on the grids, such as normalization, calculation, overlaying and classification. Ultimately, the risk assessment of traffic meteorological disasters on Highway in China was presented as in, 5 grades from high to low classified with red, orange, yellow, blue, green, respectively.
