This project has been tentatively selected and a project statement (request for proposals) is expected to be available on this website. The problem statement below will be the starting point for a panel of experts to develop the project statement.

Some types of transportation investments in older urbanized areas designed to create a more accessible and attractive community often lead to the displacement of existing residents and businesses as wealthier residents and businesses move in, attracted by the new public investment, and land values and rents increase. Gentrification, as this phenomenon is known, is frequently associated with investments in rail transit and associated transit-oriented development (TOD), although other infrastructure investments can lead to similar market forces. The overall outcome of gentrification and displacement on low-income and minority communities can be housing, job and local business instability that result in longer commutes as well as disruption to social connections and community institutions.

Research is needed to examine the role of transportation investment in creating gentrification and the investment decision-making processes that lead to them. Specifically, this research should identify strategies, policies, and data that state departments of transportation can utilize to avoid displacement and the other adverse impacts of gentrification on low-income and minority communities.
