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

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

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