TranSight Analyzes
• Construction Phase Impacts• Project Specific Financing• Emissions• Safety• User Benefits (Operating Costs, Value of Time)• Improved Mobility Agglomeration Effects!
![Page 6: Overview Examples of TranSight Applications What Does TranSight Analyze? Model Structure](https://reader034.vdocuments.mx/reader034/viewer/2022051412/55147c21550346f06e8b470c/html5/thumbnails/6.jpg)
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
