A Methodology for Disaggregation of Freight Origin Destination Data for Metropolitan and Regional Planning

Regional freight planning often requires detailed data at the sub-regional or county level. There is a dearth of sources for obtaining freight data at this level. Even the most commonly and publicly available commodity flow database, the Freight Analysis Framework (FAF), does not contain this level of data disaggregation. The absence of county-level data causes a hindrance for such agencies as Metropolitan Planning Organizations (MPO) and Councils of Government (COG) in the decision making process for regional planning and policy. The objective of this research is to use the FAF freight flows as a basis to arrive at a methodology for deriving more detailed freight flow estimates for a large metropolitan region. Freight flow data within the metropolitan Washington DC region with special attention to hazardous materials (HAZMAT) flows were used to demonstrate the methodology. Detailed freight flow estimates will enable the state and local governmental agencies to utilize this data in the transportation planning process. The goal of this research is not to eliminate the need for local data collection effort, but to provide complementary information to state and local freight programs. The paper presents the approach used for disaggregating FAF2 county level commodity flows in the tri-state area surrounding Washington, D.C.
