PROBLEM TO BE SOLVED: To provide a method and an apparatus for predicting coefficients of the sliding friction of road surfaces and capable of predicting coefficients of sliding friction of road surfaces, by creating a heat balance model and an ice-water-air balance model of the state of road surfaces, and quantitatively evaluating each model by simultaneous coupled analysis and provide its program. SOLUTION: Prediction data etc on meteorological conditions and traffic conditions are set (S100 and S101). Heat balance is computed on the basis of a previously constructed heat balance model (S102), and each balance is computed, on the basis of a previously constructed ice-water-air balance model (S103) to compute prediction data on the state of snow and ice (S104). The coefficients of sliding friction of road surfaces are determined, on the basis of the computed prediction data on the state of snow and ice (S105). COPYRIGHT: (C)2008,JPO&INPIT
