Externa marginalkostnader för olyckor i vägtrafik : uppdaterade beräkningar för det statliga vägnätet i Sverige. [External marginal costs of road traffic accidents : an update for the Swedish national road network.]

This report presents new estimates of the external marginal cost of accidents in the national road network in Sweden 2012. The researchers used a dataset where the accident database (Strada) is linked to the national road database for the years 2004—2012. The results are presented from a number of statistical models in which the researchers estimate the external marginal cost of accidents. The purpose of using several models is to test whether results from standard models are robust. In general, it seems that the results pertaining to light vehicles are quite robust across different models suggesting that the external marginal cost of traffic accidents is around 0 SEK per kilometre. The results for heavy vehicles appear less robust and while the main models suggest that the external marginal cost is around 0.25 SEK per kilometre, other models suggest that it may well be substantially lower.
