THE CONSEQUENCES OF A PROHIBITION OF STUDDED TYRES
During the spring of 1980 the discussion concerning the advantages and disadvantages of studded tyres was intensified. One of the points at issue was whether continued use of studded tyres should be permitted in view of the road abrasion caused by the studs. The National Road Administration commissioned the National Swedish Road and Traffic Research Institute to estimate the costs and benefits of a prohibition of studded tyres. The results show that the costs to the society will increase by SEK 530-1230 M annually as a result of prohibiting studded tyres. The number of accidents in slippery conditions caused by snow and ice is the completely dominant cost item. The cost savings of a prohibition of studded tyres will be sek 700-900 M annually. The largest item is simply the savings obtained by not investing in studded tyres (SEK 465-595 M annually). The cost of car washing will be reduced by about SEK 160 M per annum and the costs of road maintenance will drop by SEK 75-145 M annually. The result is consequently that the costs and benefits of a studded tyre prohibition are of the same order of magnitude. It was not possible to quantify certain consequences of the prohibition in monetary terms. Of these, the most important consequence stems from the fact that the road surface will no longer be abraded by the studs. This will result in a smaller amount of dirt on the roads during the winter, which may improve traffic safety. It will also result in lower friction levels on icy and wet roads due to the loss of the roughening action of the tyre studs. It is not possible to say which of these effects is the most important one. (TRRL)
