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

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)
