Longitudinal changes in outcomes will be assessed using multilevel mixed effects models. Participants will be measured at 3 times over 2 years of follow up. Pre-pandemic variables will be retrospectively collected. Change in health outcomes, including depressive symptoms, stress, quality of life, body mass index and behavior change constructs related to transit use will be assessed via self-report. Equity outcomes include household transportation and health-related expenditures. ![]() The primary aim is to assess change in physical activity, travel mode, and vehicle miles travelled using accelerometer and GPS devices. Participants are current staff who live either  2 miles from LRT, with equal distribution across economic and racial/ethnic strata. The TROLLEY (TRansit Opportunities for HeaLth, Livability, Exercise and EquitY) study will prospectively investigate a diverse cohort of university employees after the opening of a new light rail transit (LRT) line and the easing of campus COVID-19 restrictions. Research is needed to understand how mobility and health change as the pandemic recedes and how transit investments impact health and equity outcomes. ![]() However, health safety concerns during the COVID-19 pandemic eroded ridership, which could have longstanding negative consequences. Public transit provides a strategy to improve individual and population health through increased active travel and reduced vehicle dependency, while ensuring equitable access to jobs, healthcare, education, and mitigating climate change. The COVID-19 pandemic disrupted life in extraordinary ways impacting health and daily mobility.
