| 摘要： | In 2004, the Texas Department of Transportation (TxDOT) awarded the Center for Transportation Research at The University of Texas at Austin an implementation project that was to explain how to use the calibrated multinomial logit (MNL) models to generate county-level truck flows for Texas and to present a detailed explanation of the required steps to calibrate the MNL models in the future. MNL models were developed as part of a TxDOT research project 0-4713 entitled Development of Truck Travel Database in Texas: Identifying Sources and Methodology. Specifically, the research team was tasked with (1) embedding the MNL models into Microsoft Excel, (2) using the newly released 2002 Commodity Flow Survey (CFS) data for Texas to populate a truck travel database, (3) developing step-by-step instruction materials on using the MNL models embedded in Excel, and (4) piloting the instruction materials by providing training to district and Transportation Planning and Programming (TPP) personnel on its use. The instruction materials were piloted during a one-day workshop on August 25, 2006, at TxDOTs Riverside facility. This report documents the information presented to the workshop participants. / NOTE: Technical rept. / Supplementary Notes: See also PB2007-110180.
