Abstract
The scope of the report is to discuss the efficiency effect of the different methods for friction control of roads on the safety and accessibility due to the climatic conditions, and to establish climatic parameters that may be helpful in selecting the strategies for winter maintenance. The report is based on the analysis of the data assembled for the VTI project "Winter Model", and presents mainly comparisons between accident data, operational standards for winter maintenance and climatic conditions in the different regions of Sweden. In addition, recommendations for selecting strategies for winter maintenance are presented. (Author/publisher)
