| Zusammenfassung: | The invention discloses a road icing prediction method and system. The road icing prediction method comprises the steps of determining a relation between a meteorological factor and road icing through adopting a correlation analysis method, establishing a road icing influence index equation through combining with the influence of a road vehicle running speed verification factor on the road icing, calculating a national road icing influence index value based on the road icing influence index equation and the value of each parameter in the determined road icing influence index equation, further determining a prediction level of the national road icing influence index value corresponding to the national road icing influence index value, and according to the prediction level of the national road icing influence index, predicting a national road icing influence degree in combination with the predicted meteorological factor information and the actual road condition. According to the road icing prediction method, me |
