Ice and snow cause difficulties for road users in winter. These difficulties consist mainly of reduced accessibility and higher risks of various kinds of road accidents, which the road administrations endeavour to alleviate by maintenance measures of various kinds. Snow clearance and skid prevention treatment, such as salting of carriageways, are the two predominant kinds of maintenance measure that are taken. In this way a benefits are created for road users, but at the same time also a lot of inconvenience and costs. The maintenance costs of the road administration for these measures are directly influenced by the maintenance action taken. At the same time, there is reason to believe that road users and third parties also incur costs of various types. Different strategies for winter road maintenance may be expected to give rise to different outcomes as regards the costs and benefits of the kinds referred to above. It can thus be expected that the total costs and benefits for society at large will be affected, as well as the distribution of these among the various interested parties. Different options for infrastructure investments are generally appraised by CBA (Cost/ Benefit Analysis). The same cannot be said to hold for infrastructure maintenance measures, of which winter maintenance of state maintained roads can be taken as an example. There are many reasons for making socio-economic analyses for infrastructure maintenance also, such as the winter maintenance of state maintained roads. For this reason, we have made an analysis of how the principles that are applied concerning CBA for investments in road infrastructure could be transferred to the framework constituted by the VTI Winter Model. The objective of this analysis was to study, with reference to the principles governing traditional CBA and its application by traffic administration agencies on the basis of the recommendations from the Swedish Institute for Transport and Communications Analysis, the way in which the application of CBA to the Winter Model may be formulated.
