California Statewide Freight Forecasting ModelThe California Department of Transportation is developing a Statewide Freight Forecasting Model (CSFFM) to provide Caltrans and our partner agencies with a comprehensive freight analysis and modeling tool that will identify the individual movement of commodities transported by trucks, rail, and air.
What is the purpose of the CSFFM?
The CSFFM is being developed to better understand freight movement relatd policy, regulatory, and project decisions in California and their impacts on highway infranstructure, transportation networks, highway safety, energy/fuel consumption, efficiency of goods movement, economics and emissions. When the model forecasts commodity flows and commercial vehicle flows within California, it will take into consideration socioeconoic conditions, land use policies related to frieight, environmental policies, and multimodal infrastructure investments. Some important model inputs include socioeconomic data, exports/imports (commodity flows), trans-shipment (movement of goods from one mode to another) data, commodity-to-vehicle distribution, transport networks, and other public data sources through our freight data repository (CALFRED). Model outputs will include location-based commodity productions, location-based commodity consumptions, location-based commodity flows, and vehicle flows by mode (truck, rail, and air).
How is the model run?
The model was prepared and is run using CUBE, a commercially available transportation modeling program. Alternative future network and socio-economic scenarios will need to be run on that system.
How was the model developed?
The CSFFM is being developed by the University of California, Irvine, Institute of Transportation Studies. The model is currently being developed utilizing Citilabs CUBE, a commercially available transportation/freight modeling program. Input data will come from at least 16 different publically available freight data sources identified in CALFRED (http://freight.its.uci.edu/calfred). In addition to these data sources, Caltrans will purchase additional data to fill in missing data gaps. The anticipated completion date is June 2013.
Who will use the CSFFM?
The model will be used by planners and engineers in the Caltrans districts as well as other State Agency staff, such as the California Air Resources Board and the California Energy Commission and planners in the Metropolitan Planning Organizations and the Regional Transportation Planning Agencies.
