Applying the SWIM2 Integrated Model For Freight Planning in Oregon Prepared for the 13th TRB Transportation Planning Applications Conference May 9, 2011 Presented by Becky Knudson Oregon DOT Transportation Planning Analysis Unit
Presentation Highlights Describe Freight Plan analysis Brief overview of the Statewide Integrated Model (SWIM2) Key factors of effective modeling for long range planning Contribution of analysis to planning process
Oregon Freight Plan First statewide freight plan Scope of analysis was well matched to SWIM2 model ODOT modeling staff served role as internal consultants Consultant staff served as extension of ODOT staff Support of Freight Plan analysis Continue model development
Freight Plan Analysis Purpose Forecast range of likely economic conditions to gain understanding of effects on freight movement Illustrate variation in statewide and regional activity and commodity flows Provide information to support development of freight strategies
Analytical Approach Plan for freight flows given an uncertain economic future Use scenarios to evaluate range of possible futures Reference: “business-as-usual” (2.0%*) Optimistic: more economic growth (2.7%*) Pessimistic: less economic growth (1.2%*) High Transportation Costs: Pessimistic scenario with 3-fold increase in variable operating costs * Compound Annual Growth Rates
Oregon StateWide Integrated Model (SWIM2) as Forecast Tool SWIM is dynamic integrates the dynamic interactions of land use, the economy and transportation infrastructure SWIM1 used successfully on several statewide analyses Proved its value repeatedly Generated support for SWIM2 development SWIM2 has greater spatial acuity more detailed inputs and components Can evaluate more policy options

Effective Modeling for Long Range Planning • Myth:Sophistication of the modeling tool is the number one component of effective modeling Watson on Jeopardy
Key Factors of Effective Modeling Analysis Use models to inform and manage risk The true value of modeling comes from how the analyst uses the tool, not the tool itself Direct access to analyst Answer questions immediately, alleviate misconceptions Gain understanding of goals and objectives Analyst must have good communication skills Use good visuals - no jargon get-to-the-point - relate findings to project goals

Stronger economy generates more commodity flow in terms of value Stronger economy generates more commodity flow in terms of tons Even Better Use this…

Contribution of Modeling Analysis to the Planning Process • Source of descriptive data used to frame discussion • Described economic conditions • Illustrated regional differences • revealed patterns of activity • Use model scenarios to address risk • facilitates planning despite many unknowns • Helped identify core issues • Reduced perception of bias
Conclusions • Models are powerful tools • Effectiveness is determined by how they are used • Good sources of descriptive data • Good for evaluating “what if” scenarios, assessing risk • Using them for long range planning takes time and forethought • Planners and modelers must work together to realize the full potential of using these tools • The extra time used for analysis pays off in the end with a more productive outcome and smoother process Having our own Watson would be really, really cool
