Statewide Projects: UCD is working in partnership with Caltrans to develop two major pieces of the CA Statewide Model Framework, highlighted in yellow. The first is the STDM – which is needed first to comply with SB 375 that will assist the MPOs to address interregional travel in their models. The second is:
PECAS stands for Production, Exchange, and Consumption Allocation System. The PECAS Project is a collaboration between the University of California and Caltrans to develop models for spatial economic analysis and prediction. , and ULTRANS has the resources to provide the objective research needed.

The California Statewide Interregional Integrated Model, known as CalSIIM, integrates transportation, economic, demographic, and land use information to predict the exchange of goods and services across space and time. It could also be used to assess the potential effects of various types of large-scale policies, programs, and strategies, such as:
~ Costs and benefits of major infrastructure investments ~ Travel between California's regions and counties ~ Habitat and species protection strategies ~ Preservation of agriculture areas ~ Clean Air policies and programs ~ Clean Water Act compliance ~ Economic Development Programs ~ Jobs/Housing Proximity ~ Various housing policies and programs ~ Redevelopment and urban infill strategies ~ Regional job production and job creation programs
Integrated modeling tools can substantially advance our ability to make wiser land use and transportation decisions—decisions that include consideration of land use, environmental, and economic impacts. Use of models will strengthen communication between regions across California and provide effective outreach statewide and nationally in support of sustainable transportation and community development policies. The outcome of these efforts could be a revolution in land use management, urban design, and traveler behavior, and lead to a transformation of the entire transport system.
The Sacramento region is home to a world-leading modeling center, the Urban Land Use and Transportation Center (ULTRANS) within the UC Davis Institute of Transportation Studies. The Sacramento Area Council of Governments (SACOG) is a national leader in the regional integrated modeling of land use, transportation and economic activity. ULTRANS is producing the most comprehensive statewide model that addresses these same planning factors. These two modeling powerhouses are joining forces to provide leadership and support for regional planning through integrated modeling tools to regional governments across California, with an ongoing series of activities to develop sustainable community strategies with all the co-benefits of this type of planning, including GHG reduction, community livability and mobility enhancement, and efficient planning and decision making.
