CHAPTER 1 Background The TRB SHRP 2 Second Symposium on Innovations in Freight Demand Modeling and Data (C43) was organized to assess the progress of freight modeling research initiatives advanced by the Freight Demand Modeling and Data Improvement Strategic Plan (C20), completed in 2013, and the 2010 Freight Modeling and Data Symposium, which was held in 2010 as part of the C20 project. The symposium also acted to share insights on how the modeling practice has advanced and how C20 recommendations have been integrated into public-sector and private-sector practical research applications. Participants in the symposium represented a cross-section of the freight modeling community, including academic research institutions, states, metropolitan planning organizations, businesses that rely on logistics for their operations, and the international community. A call for papers was advertised on June 18, 2013, through TRBâs newsletter, with a deadline of August 15, 2013. This call for papers noted particular gaps in research that served as motivation for responses and selection of abstracts, including â¢ Lack of regional planning organizations incorporating freight into their transportation plans, â¢ Private-sector logistics decision makers assuming that the public sector can meet their needs, â¢ Private-sector decisions that reflect large-scale public decision making, â¢ Public-sector data accumulated on a national level that gets disaggregated to state, regional, and local areas, and â¢ Disconnect in knowledge, availability, and sharing of private-sector data with public- sector planners. Topics suggested, but not limited to, were â¢ Public planningâprivate supply-chain linkages â¢ Modeling and logistics data integration â¢ Freight reliability â¢ Global logistics trends impacting freight modeling and data Approximately 75 abstracts were submitted, of which 18 were chosen for presentation and eligibility for one of the two symposium awards: (1) the best private-sector idea that is most applicable to the public sector, and (2) the public-sector idea that best demonstrates linkage to private-sector models, data, or methods. 1
The symposium was held on October 21â22, 2013, at the Crowne Plaza in Herndon, Virginia. Approximately 65 participants attended, including the presenters. The 2-day symposium was broken down into six sessions, based on categories of areas of research interest. Each session was composed of two or three presentations, each followed by a question-and- answer discussion involving the entire audience and the presenter. The symposium included a diverse audience representing academia, public-sector practitioners, and private industry. Participants examined, evaluated, and promoted innovative and promising advances in freight demand modeling, data collection, and freight forecasting research methods. Local, state-level, regional, and domestic and international models were presented. The agenda and list of presentations appear in Appendix A. The electronic files for the presentations and the papers can be retrieved from http://www.trb.org/strategichighwayresearchprogram2shrp2/pages/shrp2_freight_symposium_90 6.aspx and www.freightplanning.com. The presentations were judged based on 13 parameters, including methodology, practicality, ease of use, clarity of purpose, research value, and results. A panel of experts, representing transportation modes, public and private sectors, geographies (international and domestic), technology, and analytical techniques judged the competition. Finally, feedback forms were handed out to the attendees and were collected on both days. 2
