Hälsoeffekter, påverkar de acceptansen för prissättning av vägtrafik?

Road traffic makes important contributions to the pollution levels in urban areas. Of the pollutants, particulate matter, makes the greatest contribution to the external cost due to their detrimental impact on human health. Economic policy measures such as road pricing can be used for the regulation of traffic, thereby improving local air quality, but there is often a large resistance towards these types of measures. The purpose of this study has been to investigate if it is likely that the health impact of traffic emissions influences the acceptance for road pricing. In this study we have done a literature survey to explore this issue. The conclusion is that it is unlikely that the health impact influences the acceptance. An important reason is that the public knowledge about this health impact is low and therefore the health risks are underestimated. We have also found that there is a need for deeper investigation into people´s knowledge about traffic emissions and their health impact and how this in turn influences their decisions regarding policy measures, such as road pricing that aims at reducing the health impact. The conclusion is that the best method for this would be a so-called Stated Preference study.
