Brief Summary
The researchers are evaluating longitudinal changes in multiple health, economic, and environmental outcomes over a 3-year COVID recovery period and in the context of a new light rail transit (LRT) line, called the Mid-Coast Trolley, among 465 UC San Diego (UCSD) staff. The primary aim is to evaluate change in objectively measured total and moderate to vigorous physical activity (MVPA), travel mode, and vehicle miles traveled (VMT).
