Abstract

This paper discusses the opportunities of sectoral freight transport demand models. The work is based on literature and insights from interdisciplinary research in the field of production, logistics and transport. First, current and future factors influencing freight transport are discussed. Next, a brief summary of the traditional transport modelling approach and recent extensions and adaptations of freight transport models is given. As interdisciplinary research has shown, the impact of the identified factors on the development of freight transport is strongly dependent on the sector under investigation. As a consequence, this paper proposes the application of a sectoral modelling approach. The automotive and food sectors in Germany are used as examples to further examine the opportunities of sectoral freight transport demand models.

5. Conclusion

We have shown thatthere are a wide variety of developments in freight transport that cannot be explained with the traditional four-step approach of passenger-transport modelling. We have presented sectoral freight transport modelling as an approach that can contribute to current advances in this area and open up possibilities for new applications. As we have shown for the automotive and food sectors, sectoral models can unleash the potential of data sources that are already available. The sectoral approach also benefits from the homogeneity of planning problems along supply chains. By comparing the automotive and food sectors, we demonstrate that such models will have different focuses depending on sector-specific development factors of freight transport.
