A rough quantification of the skidding problem shows that today this is chiefly a road safety problem. However, to make the different measures available against skidding, it will be necessary to make a complete evaluation of the consequences. Thus the effects of the measures chosen will have to be considered with regard to (1) road safety, (2) trafficability, (3) vehicle costs, (4) costs on the part of the body responsible for the road and (5) environment. The most important methods used today to reduce skidding problems are salting and sanding and the use of studded tyres. The effects of studded tyres are relatively well known as demonstrated in previous studies, whereas the effects of de-icing through salting have not been sufficiently elucidated on salient points. In a year or so, the first comprehensive evaluation of the pros and cons of salting is to be made which will be based on findings made in the studies now in progress. A review of the present knowledge and of the research and development work pursued today in search of further improvements of current de-icing methods and studded tyres, including the possibilities of alternative and additional measures, shows that there is a need for better coordination of this research. A proposal is given for the establishment of a reference group made up of various interested parties in the field. The function of this group should be to coordinate and in different ways to promote research, the objective of which is to give the incentive to various actions which in the long run would bring about a radical improvement of the poor safety situation prevailing today under icy and snowy road conditions.
