Presentation Transcript

  1. Overview • Examples of TranSightApplications • What Does TranSight Analyze? • Model Structure

  2. Transportation Applications • Long-Range Planning • Demand Management • Evaluating Financing Mechanisms • Capturing Benefits of Transit Investments • Benefit-Cost Comparison by Project • Large-Scale Multimodal Investments • Lane Closure/Reconstruction

  3. Case Study Preview - Impacts of I-405 and SR509 Expansion in Washington

  4. TranSight Analyzes • Construction Phase Impacts • Project Specific Financing • Emissions • Safety • User Benefits (Operating Costs, Value of Time) • Improved Mobility Agglomeration Effects!

  5. Construction & Financing • Detailed by $ amount of investments • Construction labor and materials • Professional services • Special Equipment • Captures the effects of project spending over time and accounts for economic feedback of projects financed through: • user fees such as tolls • other mechanisms such as tax increases

  6. Emissions • Estimated based upon Vehicle Miles Traveled (VMT) and Vehicle Hours Traveled (VHT) • TranSight examines CO, NOx, SOx, PM10, and VOCs and the health costs associated with them • Adjustable parameters

  7. Safety • Accident rates influenced by changes in VMT • Categorized by accident type by Fatalities, Injuries, and Property Damage Only • Adjustable parameters

  8. User Benefits • Estimates fuel and non-fuel operating expenses • Value of time • Based upon VMT, VHT, regional wage, and fuel efficiency • Adjustable parameters

  9. New Economic Geography The New Economic Geography : The Impacts of Agglomeration Economics. • Focus: • Access to labor and material inputs for industries rely on a good transportation system • Productivity gains are realized due to dense labor and product pools • Trade flows such as region-to-region transportation links are the conduit for regional economic growth

  10. Mobility, Agglomeration, and the Cost Matrix • Driven by adjustments in VMT, VHT, Trips • Calculates changes to the “Effective Distance” between economic regions: • Commuter Cost Matrix • Accessibility Cost Matrix • Transportation Cost Matrix

  11. Structure • Simple to Operate • Transparent Structure • Project Specific • Robust Results

  12. Transparent Structure

  13. Examples of Result Types • Jobs (by industry) • Gross Regional Product (by final demand and value-add) • Personal Income (by income accounts) • Productivity (by industry) • Output (by industry) • Trade Flows (by industry) • Population (by industry)

  14. TranSight estimates the total impact of transportation projects on the local economy including: • Construction Phase • Emissions and Safety • Productivity Impacts (through agglomeration)

  15. Coming Up Next Time Session 2 • Interfacing with the tool • Developing simulations Session 3 • Review of client applications
