This study examines the implementation of integrated economic models by California's MPOs and recommends data sharing and statewide adoption. The models help test policy, planning, and investment alternatives, with a focus on economic benefits, equity, and environmental considerations. The study provides insights into how these models can conform to various statutory requirements.

Recommendations • The four large MPOs (SCAG, MTC/ABAG, SANDAG, and SACOG) strongly consider implementing an integrated economic model in the near future. • Medium-sized MPOs and RTPAs in California consider implementing simpler urban models, such as PLACES, What If?, UPlan, and others. • Data sharing should be instituted among MPOs, RTPAs, and Caltrans (much like NYMTC Strategic Data Coordination Effort). • Caltrans should consider implementing a statewide integrated interregional urban model.

Results/Status • SACOG calibrating PECAS, SANDAG developing PECAS, SCAG at RFP stage for integrated economic model, ABAG assembling data for integrated economic model • 18 Medium-sized MPO/RTPAs have installed and are using UPlan integrated with their travel models. • Data sharing begun between SCAG, SANDAG, ABAG and SACOG. Center for data management being given funding consideration by State • First phase of statewide demonstration interregional PECAS model finished in June 2008. Second phase demonstration PECAS model complete June 2009. First production PECAS model expected in June 2010

Moreover • 1. These models allow us to test a wide variety of policy, planning and investment alternatives • 2. They create a consistent set of economic rules and criteria to test the alternatives. • 3. They respond to a wide variety of statutes requiring more accurate forecasts than in the past.
Most Importantly It’s About the 3 E’s • Economic benefits for the state and its counties • Equity: benefits for households by income • Environmental • Air quality and GHG production • Conversion of habitats and ag lands

Now how will this help conform to statute? • SAFETEA-LU 4 objectives • Increase mobility and economic development • Decrease pollution and Green House Gasses • Context sensitive planning • Scenario Planning
How will this help conform to statute? • Clean Air Act • GHG Measures • Clean Water Act • Runoff • Civil Rights Act • Environmental Justice • Executive Order 12898 • FESA • Conversion of habitat for listed species
What Did It Cost Them: Staff • Forecast Program Manager • Transportation Modeler • Land-Use Modeler • Regional Economist • Socio-Economic (Demographic) Modeler • Programmer (Advanced)
What Did It Cost Them: Data • Transport • Transport costs for goods and services • Off-peak auto times and cost skims from travel model • Value of time and commuting cost for labour • Land Use • Land cover data with existing use, zoning, vacant/protectedintensity of development • Floorspace • Real estate prices by TAZ • Typical floorspace use rates by household type and housing type from PUMS
What Did It Cost Them: Data • Typical floorspace use rates by employment type • Relative quantity of housing by zone from Census SF3Crosstab of space type by household type • Relative quantity of housing by zone from Census SF3Crosstab of space type by household type • Construction cost data • Employment • Employment by occupation and household category • Occupation by industry crosstab from PUMS ES202 or InfoUSA data on employment location • Census • Census household distributions by TAZ
What Did It Cost Them: Time • Time • Build • 2 Year minimum process • 3 Years easier on everybody • Run • About 30 hours per scenario
What Are They Doing Next • SACOG will finish calibration and study investment and policy • SANDAG will use their model to figure out how to direct development to the nodes they recognized in their Regional Comprehensive Plan • The Statewide model will be used by the Governor’s Office for interagency infrastructure investment decisions
