Abstract: The objective of this report is to recommend a new
commodity classification for the next version of the Swedish national
freight model system Samgods. The recommendation is based on i) a
comparison of commodity classifications in transport models in other
countries, ii) an evaluation of classifications in from the viewpoint of
modelling transport demand, iii) how well the classification captures
behavioral differences among firms in the freight market and iv)
statistical considerations. We recommend the classification to be based on
the divisional level of the NST 2007 and to include commodity groups 1-14.
We recommend to split up group 1 into one category containing round wood
and another containing the rest of the items. We also think it is useful to
add a commodity group for air freight by combining fractions from other
commodities. In total, our recommendation consists of 16 groups.
