摘要:The article studies possibility by using the data of the Road Weather Information Systems to forecast the beginning of precipitation on the roads maintained by the state road maintenance enterprises. The article discusses the importance of forecasts both to the road users as well as road maintenance enterprises, especially in a cold period of the year. The hazards caused by meteorological phenomena specific of winter season are presented. Research methodology is described which is based on the speed of movement of clouds carrying precipitation. To calculate speed the theoretical background is given assisting in selection of certain parameters for the determination of this value. Knowing the speed of movement of clouds the forecasts have been made. Results of the forecasts are compared to the real parameters and it is determined in what radius the forecasts are advisable to be made.
