SAMKOST: redovisning av regeringsuppdrag kring trafikens samhällsekonomiska kostnader

Anna Johansson

In December 2012, the Swedish government commissioned VTI to update the social marginal costs for using infrastructure for all modes of transport based on state-of-the-art knowledge in the research community. The task has been implemented by defining projects addressing all externalities of relevance for the assessment, i.e. infrastructure wear and tear, accident risks, emissions from the use of fossil fuel, noise as well as shortage of capacity. The overall assessment of marginal costs of road use is not far from the level in previous domestic studies. Behind this average, a new approach to estimate the costs to the infrastructure holder of heavy and light vehicles using roads, results in cost estimates that are higher than before. Other cost components, in particular the social costs for road accidents has however been reduced. Also the estimates of the costs originating from emissions and noise are lower than before. The marginal costs of railway services are now higher than before, in particular for freight trains. The single most important change also in the railway sector is the increase in costs for infrastructure wear and tear. These results represent national averages for roads and railways. A graphical representation of costs is also offered in order to address the degree of cost-level differences across the networks. It is obvious that costs for noise and emissions are higher the closer people live to traffic using the network. Clear differences with respect to maintenance costs are also observed, but overall this aspect of the results is not yet ready for providing the basis for a comprehensive policy discussion.



Cost Benefit Analysis (CBA) workshop in Stockholm

An open seminar and workshop in Stockholm will be held on 25-26 April 2018. The workshop deals with the use of CBA as a basis for decision-making in the public sector. The workshop is organized by, among others, Professor Jan-Eric Nilsson, VTI.
