Estimating Freight Flows for Metropolitan Area Highway Networks Using Secondary Data Sources

State-of-the art of freight forecast modeling: lessons learned and the road ahead

“…This model was incorporated into de Jong and Ben-Akiva's (2007) model. Giuliano et al (2007) addressed the issue of data insufficiency by using secondary data sources to estimate commodity freight flows at a resolution from which a singular data source is not available. The resolution of existing public data such as the Commodity Flow Survey only goes down to the level of the aggregate metropolitan area.…”

“…The gravity model in the class D can be replaced with the fractional split model developed by Sivakumar and Bhat (2002) or the tour-based gravity model by Wang and Holguín-Veras (2009). Secondary source reconciliation methods shown by Giuliano et al (2007) can be used to estimate flows at a higher resolution of detail such as county to county.…”

“…California is also home to the Ports of Long Beach and Los Angeles in the San Pedro Bay, the largest container port in the U.S. and the fifth largest in the world (Giuliano et al 2007). Hensher and Puckett (2005) and Giuliano et al (2007) discuss some of the attributes that make an ideal freight demand model: a strong behavioral foundation; a multimodal scope; incorporating freight and passenger interactions; and capable of handling policy changes. However, many modeling efforts fall far short of meeting these objectives.…”

TransNIEMO: economic impact analysis using a model of consistent inter-regional economic and network equilibria

“…This research was elaborated to extend the geographically limited version of TransNIEMO by to address the regional freight transportation models discussed in Gordon and Pan (2001), Pan (2006), and Giuliano et al (2007), to analyze interregional and interstate freight flows, and to simulate the response of highway freight flows to disruptions in the national level. It uses data from the U.S.…”

“…An equilibrium model is applied to estimate freight flows in the baseline and for the bridge collapse scenario. Freight tonnage was converted to passenger-car equivalent (PCE) values based on the ton-per-PCE ratios estimated by Giuliano et al (2007).…”
