Winter tyres : Traffic safety

• During the winter 1993/94, the Swedish National Road Administration received considerable criticism for its winter maintenance and in particular for the high consumption if road salt. This led to discussions on changing the rules for winter maintenance. Some ice or snow was temporary allowed on the roads with high winter maintenance standard. More roads were degraded to lower winter maintenance standard where ice or snow were permanently permitted. In addition, certain changes intended to influence driver behaviour and vehicle equipment for example mandating the use of winter tyres were to be studied. The purpose of the first investigation described in this paper was to calculate the socio-economic consequences that may be expected from a requirement on winter tyres in various circumstances. In the second investigation in this paper the traffic safety effect of the requirement is studied. A requirement of using winter tyres when it is slippery was selected based on facts from the first investigation.
