Transit Impacts Research Program (TIRP)

The Transit Impacts Research Program (TIRP) studies the contributions of transit to mobility, economic development and job access, equity and opportunity, public well-being and safety, and sustainability. The program aims to provide information to optimize transportation investments, regional connectivity, and system effectiveness.

The program was launched in 2006 to study the impacts of investments in Twin Cities transitways. In 2023, the program's scope was expanded to include analysis of the overall transit system, including potential projects throughout Minnesota.
