Assessment of the 1997 Commodity Flow Survey for State-Level Freight Transportation Planning

The objective of this study was to explore the possibility of disaggregating Commodity Flow Survey (CFS) data to a zonal level that is compatible with statewide freight modeling. The Commonwealth of Kentucky served as the study area for this investigation and its counties form the zonal system used in the analysis. Two tasks were undertaken as part of this study. First, regression models were estimated using CFS data. The models were then applied to Kentucky counties to predict freight productions and attractions. Second, in an effort to ascertain how well the modeled results conform to reality, they were compared to TRANSEARCH data, which served as surrogates for actual freight productions and attractions. This report is presented is five sections. Section 1 provides an introduction. In Section 2 the CFS and TRANSEARCH data are described briefly with emphasis being placed on differences between the two databases. These differences are nontrivial as they can impact the interpretation of the study results, which are presented in Section 4. Section 3 discusses briefly the development of regression models for use in freight production and attraction at the county level. Finally, conclusions and recommendations are presented in Section 5.
