1. Freight Demand Modeling: Tools for Public-Sector Decision Making First National Conference September 25-27, 2006 Washington D.C. Sponsored by TRB FHWA U.S. ACE RITA FRA Kathleen Hancock PE, PhD Associate Director CGIT Virginia Polytechnic Institute and State University

2. to provide participants with an appreciation of –the importance of freight transportation –the role of analytical tools to describe and predict the impacts of modal trade patterns on the public and private transportation systems to engage members of the freight transportation community in –examining current modeling practice –identifying areas where improvement is needed GOALS

3. Key Observations Freight and logistic sectors critically important Political and jurisdictional boundaries do not define market interrelationships

4. Megapolitan vs Political Boundaries Source: R E Lang and D Dhavale, “Beyond Megalopolis: Exploring America’s New “Megapolitan” Geography”, METROPOLITAN INSTITUTE CENSUS REPORT SERIES, Census Report 05:01 (July 2005).

5. Key Observations Different decision tools for different contexts

6. Decision Making Context Multi-National (e.g., NAFTA) Global National / Federal MegaRegions, Multi-state, Market-oriented, Trade corridors State Metropolitan Local/Site

7. Key Observations Decisions very broad / multidisciplinary

8. Strategic Investment Decisions System (Real Time) Operations System Management System Planning Econometric models Input-output Network flow/land use/impact models Trend analysis Logistics modeling Micro simulation Data analysis Heuristics

9. Modeling Context Four-step model paradigm an artifact of passenger demand modeling Not just one type of model –logistics models –flow models –micro-simulations –Econometric models –hybrids, etc Maybe one does not need a model

10. Domain Context Marriage of different disciplines –regional economics –industrial engineering –civil engineering –urban geography –logistics –management/business, etc. Multidisciplinary approach to research

11. Key Observations Data mandatory

12. Data Context Data collection paradigm of periodic data updates outdated….need examination of continuous data input Data partnerships - “harsh dose of reality”

13. Key Observations Freight and logistic sectors critically important Political and jurisdictional boundaries do not define market interrelationships Different decision tools for different contexts Decisions very broad / multidisciplinary Data mandatory Education of decision makers, users, providers important

14. The MATRICES

15. General Research Needs Best practices in modeling and other techniques and data for different decision making contexts Guidance on “how to get there” Syntheses of the current state of the knowledge

16. Research Needs—Geography Data and decision tools depend on the level of geography being considered Robust national freight flow model

17. Research Needs—Data 1 National data on through-metropolitan area movements Development of a “freight data architecture” and application scenarios Systematic and linked approach toward data collection and use Leadership in using available public and private databases

18. Research Needs—Data 2 Assessment of ITS technologies PUMS equivalent for freight geographic information Approach to capture raw trend data on a routine basis and industry wide Move from traditional paradigm of periodic, five-year data collection to continuous flow of data Sub-sample updating and sample size increase of CFS Bayesian decision networks

19. Research Needs—Data 3 More surveys when conducting decennial census Case studies of where collaborative data efforts have occurred Transfer of data conclusions and underlying relationships Better understanding of the transfer of methodologies and data use

20. Research Needs—Data 4e Best practices of truck origin-destination collection methodologies and classification count matrices Additional guidance like Quick Response Freight Manual Information about “logistics for public receivers”, ie government buildings, schools Relationship between land use and freight data Improvements and survivability of CFS and VIUS

21. Research Needs—Decision Support Tools 1 Freight Model Improvement Program (FMIP) Key variables and relationships among variables for shipping decisions Guidance like Quick Response Freight Manual Strategies to communicate applicability and value of different decision tools Decision support tools that incorporate uncertainty and risk

22. Research Needs—Decision Support Tools 2 Link to modeling at more disaggregate geographic levels from national models Proof of model’s value and viability be disseminated…feedback loop Comparison of state-of-the-art models Freight operational models within decision analysis framework

23. Research Needs—Decision Support Tools 3e Safety module as post processor of freight modeling Decision tools that link econometric and transportation models Decision tools that incorporate logistics Multimodal and intermodal understanding; including short sea shipping, inland water, air cargo, etc. Analysis tools that show environmental and land use effects of different investment and operational strategies at metropolitan area and local levels

24. C Challenge “The four Cs” How to develop a constituency for the results of freight planning How to develop a constituency for the results of freight planning that is led by champions How to develop a constituency for the results of freight planning that is led by champions based on collaborative undertakings constituency championscollaborative customer How to develop a constituency for the results of freight planning that is led by champions based on collaborative undertakings that responds to customer (of the information) needs?
