2. Outline • Introduction • Recent developments • Existing models in Belgium • Missing elements • Key elements for new framework • Conclusions Tabitha Maes - SHRP 2

3. Introduction Flanders • Northern part of Belgium • Key region for logistics in Europe • Main port of Antwerp Tabitha Maes - SHRP 2

4. Recent developments • State-of-the-practice models = four-step models • Based on passenger transport models • Looking at aggregated flows • Lacking elements of logistic behavior • No representation of the different agents • Main difference with passenger transport • More agents in decision making process • Recent trends = agent-based models • Focus on each agent separately • Model individual operational decisions • More disaggregated approach • Allows better representation of logistics Tabitha Maes - SHRP 2

5. Existing models in Belgium • Four freight transportation models • Walloon Freight Transportation Model (WFTM) • Four-step model for Wallonia; 1990’s • Used to develop a freight transportation plan for 2010 • Model of TRITEL • Four-step model for Flanders; 2006 • Integrate logistic centers into the road matrix • Step towards integrating logistic aspects • PLANET • Belgian model; 2008 • Both passenger and freight transport • Traditional commodity-based four step model • MOBILEC (MOBILity\Economy) • First used in the Netherlands, adapted for Belgium; 2004 • Land-use transportation interaction model • Describes the interaction between transport and economy Tabitha Maes - SHRP 2

6. Existing models in Belgium • Similarities • 10 NST/R commodity categories • Zoning at NUTS3 level = 43 “arrondissements” of Belgium • Three main transport modes • Road • Rail • Inland waterways • Disadvantages • All models are at the aggregated level • Little or no inclusion of logistic elements Tabitha Maes - SHRP 2

7. Missing elements • Aggregated level • No representation of the different actors • No explicit links between economic activity and transport • Lacking elements of logistic organization • TRITEL model: first attempt with TLN for truck transport • WFTM: • allows representing transshipping and transiting • intermodal combinations Tabitha Maes - SHRP 2

8. Key elements for new framework Production & attraction Distribution Logistic decisions Network assignment Tabitha Maes - SHRP 2

9. Key elements for new framework • Agent-based micro simulated model for Flanders • No loss of information due to aggregation • Characteristics of freight transport • Include individual firm characteristics • Detailed representation of commodity groups • Tracking of single movements of goods • Relationship with the economy • Microeconomic background of commodity groups • Integrating future logistic challenges in supply chain management Tabitha Maes - SHRP 2

10. Key elements for new framework Shipper Logistic actors Receiver • Choice of the agents • Logistic elements Tabitha Maes - SHRP 2

11. Conclusions • A new innovative framework for Flanders based on: • An agent-based micro simulated model • Better representation of logistics • A better understanding of the interactions between agents • Further research has to be done to develop a prototype model and to collect the required data Tabitha Maes - SHRP 2
