The Transitway Impacts Research Program (TIRP) answers questions about the economic, travel, and community impacts of transitway corridors in the Twin Cities metropolitan area.
The research program is measuring the impacts of transitways on property values, land use and housing mix, businesses, travel behavior, environment and public health, safety, and community cohesion. The program was launched in 2006 by the Hennepin County-University of Minnesota partnership and has grown to include a mix of funding partners and program supporters.
