This report describes the outcomes of an idea study on a new national freight transport model system for Sweden. The objective of the study is to provide state-of-the-art ideas that are consistent and innovative on a conceptual framework for policy orientated analyses and modelling of freight transport in a Swedish context. The new Swedish freight transport model system, that should succeed the present SAMGODS model, should cover all modes (road, rail, air, maritime) and geographic levels (international, national, regional). Furthermore, it should be able to provide medium and long run forecasts (certainly including 10-25 years ahead), and be capable of being used to assess transport policy measures and to evaluate infrastructure projects.
