Översättning av VTI meddelande 756. "Dubbdäck: samhällsekonomiska konsekvenser"

The goal with this investigation is a revision of earlier investigations of studded tyres, i.e. the socio-economic consequences that may be expected from a ban on such tyres. The calculations were made for winter 1993/1994 and for winter 1999/2000. The conditions in winter 1993/1994 form the basis for the calculations, a quite normal winter. The conditions in 1999/20 00 are the same, except for the assumptions that all those using studded tyres will then be using lightweight studs and that wear resistant pavements will be more common. Everything else, for example winter maintenance will be the same as in 1993/1994. The following effects are included: Accidents (direct: at slipperiness. indirect: because of pavement wear) Road wear (pavement and road markings, cleaning signs) Car costs (tyres/rims, fuel consumption, washing) Environment (car washing)
