Transportation Equity Innovation (TrEI) Lab

Welcome! The Transportation Equity Innovation (TrEI) Lab is led by Dr. Tierra Bills and aims to develop innovative, meaningful, and effective tools for assessing fairness in transportation infrastructure, systems, and policies. We are a team of researchers and students and our research approach includes multiple pathways for advancing transportation equity. These themes include representativeness in travel activity data, innovations in travel model development, and effective measurement of equity impacts from transportation investments.
