RoadSurf 1.1: open-source road weather model library

Virve Eveliina Karsisto

Abstract. Icy and snowy road conditions cause problems in many countries where temperature often drops below zero degrees. Preventive actions are necessary to keep roads ice-free and to optimize maintenance operations. Accurate road surface temperature and road condition forecasts are an essential help for road maintenance crews to plan their actions. Finnish Meteorological institute (FMI) has produced road weather forecasts for many years with the house-made road weather model RoadSurf to aid local road authorities. Recently, FMI published an open-source road weather model library that consists of RoadSurf functions. The open publication provides an opportunity for many institutes and companies to use the library in road weather forecasting. The evaluation of the library shows that it is well suited for forecasting road surface temperature.

Short summary
RoadSurf is an open-source library that contains functions from the Finnish Meteorological Institute’s road weather model. The evaluation of the library shows that it is well suited for making road surface temperature forecasts. The evaluation was done by making forecasts for about 400 road weather stations in Finland with the library. Accurate forecasts help road authorities to do salting and ploughing operations at the right time and to keep roads safe for drivers.
