Overview • Examples of TranSight Applications • What Does TranSight Analyze? • Model Structure 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 Case Study Preview - Impacts of I-405 and SR509 Expansion in Washington 12,000 10,000 Emploment (Units) 8,000 6,000 I-405 SR509 4,000 2,000 0 -2,000 2005 2007 2009 2011 2013 2015 2017 2019 2021 2023 2025 2027 2029 2031 2033 2035 2037 2039 TranSight Analyzes • • • • • • Construction Phase Impacts Project Specific Financing Emissions Safety User Benefits (Operating Costs, Value of Time) Improved Mobility Agglomeration Effects! 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 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 Safety • Accident rates influenced by changes in VMT • Categorized by accident type by Fatalities, Injuries, and Property Damage Only • Adjustable parameters User Benefits • Estimates fuel and non-fuel operating expenses • Value of time • Based upon VMT, VHT, regional wage, and fuel efficiency • Adjustable parameters 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 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 Structure TranSight Project-Specific Data Construction Operation Finance Economic Results EDFS Policy -53 Insight Transportation Model VMT VHT Fuel Demand Emissions Safety REMI Policy Variables Transportation Cost Matrix • • • • Simple to Operate Transparent Structure Project Specific Robust Results Transparent Structure 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) TranSight estimates the total impact of transportation projects on the local economy including: • Construction Phase • Emissions and Safety • Productivity Impacts (through agglomeration) Coming Up Next Time Session 2 • Interfacing with the tool • Developing simulations Session 3 • Review of client applications
