The 2030 Group (a business organization in the Washington, DC area) and Northern Virginia Transportation Alliance teamed to fund a study of the economic benefits of expanding multimodal transportation options in the Washington, DC region. The study used TREDIS to assess the regional economic significance and economic impact of proposed alternatives scenarios for long range transportation investment.
The study assessed how alternative investment scenarios would lead to changes in congestion and reliability conditions, as well as broader labor market access to jobs and truck delivery access within the region. TREDIS was used to estimate how the alternative packages of highway and transit projects would then affect specific parts of the region and specific sectors of the economy over time. Impacts on patterns and growth rates for jobs, wage income, value added (GRP) and business output (sales) were estimated, as well as local and state tax revenues.
