External cost for air pollution and noise due to traffic on state roads
Overview
Objectives:
In December 2012, the Swedish government commissioned VTI to update the social marginal cost for using infrastructure for all modes of transport based on state-of-the-art knowledge in the research community. The task only involved state roads.
Methodology:
The Impact Pathway Approach has also been used to perform the calculations using Swedish data focusing on health. In these calculations there has been placed particular emphasis on how the influence of population density in the vicinity of roads influence the results from these calculations.
For noise we developed an exposure function based on the new EU-CNOSSOS model which accounted for the location of buildings close to a road while for air pollution we used results based on detailed calculations in the Stockholm area.
