A Guide to State DOT Consideration of Economic Development Potential in Planning

ICF Consulting for the AASHTO Standing Committee on Planning, NCHRP 8-36-60, March 2007

 

ICF was commissioned the Guide to discuss tools available for assessing economic development potentials in statewide planning. On pp.33-34, it discusses TranSight, ReDyn and TREDIS.

 

..."Like REMI’s TranSight, TREDIS (the Transportation Economic Development Impact System) is a dynamic economic model that specifically focuses on transportation projects. Like ReDyn, TREDIS is a web-based, modular tool. The user inputs details about the project, from which TREDIS calculates primary, secondary, and tertiary impacts. The final outputs of TREDIS include employment by industry, personal income, gross regional product, business output, national and state benefits, and export activity. A further layer of analysis included in TREDIS is benefit-cost calculations."

 

..."The calculation of user impacts is not inherent in dynamic economic models. Generally, user impacts must be provided as inputs. However, models that incorporate transportation planning and travel demand forecasts, such as TranSight and TREDIS, will calculate user impacts of transportation projects as part of their processes."
