The American Public Transportation Association, through the Transit Cooperative Research Program, commissioned a study of the economic impacts of public transportation investment. The consultant study team included use of input-output models to assess job and income impacts of public transportation spending. It used TREDIS to calculate the potential impact of sustained public transportation investment on houshold and business costs and productivity, as a result of changes in car use, traffic congestion and labor market access.
Scenarios were developed to illustrate alternative levels of national support for public transportation, and TREDIS was applied to show short-term and long-term impacts on growth of jobs, income, GDP and business output over time.
