Study on Grades of Freeway Meteorological Disasters by Risk Matrix
Abstract:
Meteorological disasters have a negative influence on highway safety operations. In order to efficiently enhancing emergency response capabilities for prevention of meteorological disasters and to carry out study of the ranking of risk factors about meteorological disasters, fuzzy mathematical method (expertise method) was applied to estimate the two indexes of risk factors of meteorological disasters in freeway normal operation: probability of risk factors and losses value of risk factors. Risk matrix method was used to analyze qualitatively and quantitatively the potential risk factors of meteorological disasters. By analyzing the potential risk factors of meteorological disasters in the normal operational process of a freeway in south China, it came to that risk level of typhoon was divided into four levers, dense fog and heavy rain were three, thunderstorms and heat were two. The result was consistent with the actual thing, and it provided a good analytic basis for follow-up emergency strategic planning.
