Framkomlighet under vintern på vägar med årsdygnstrafik mindre än tusen fordon: norska mätningar
Swedish National Road and Transport Research Institute.
2008 (Swedish)Report (Other academic)
Abstract [sv]

The Norwegian Public Roads Administration has expressed a wish that the expertise of VTI in infrastructure maintenance should be utilised to improve the decision base for the best possible operation and maintenance of the Norwegian road network. VTI was therefore commissioned to estimate the effects for road users of a number of operation and maintenance measures and strategies. This report gives an account of one of the projects. At VTI, within the project Tema Vintermodell, a methodology has been developed to study the accessibility of vehicular traffic in different road conditions. Vehicle speeds are continually measured during the winter season with simultaneous observations of the prevailing weather and road conditions. The reductions in speed in different road conditions, in relation to speeds on dry bare roads, can thus be calculated. The Norwegian Public Roads Administration considers that, for Norwegian conditions, it is most important to study the road network carrying low volumes of traffic, with an average annual daily traffic (AADT) less than ca 1,000 vehicles.
