Abstract:The goal of this research is to develop a two-stage approach for estimating truck origin-destination (O-D) trip table using both commodity flows and truck counts. The specific objectives of this research include the following: (1) Investigate and update the statewide truck data from the following data sources: Freight Analysis Framework version 3 (FAF3), a newly released national commodity O-D database, the up-to-date statewide truck count programs, and the Utah Statewide Travel Model (USTM). (2) Develop a commodity-based truck trip table from FAF3 for the state of Utah. (3) Refine the commodity-based truck trip table using truck counts obtained from the statewide truck count program and the USTM. A case study using the Utah statewide freight transportation network is conducted to demonstrate the application of the proposed method.
