Walking, cycling, and taking the bus or train are healthier travel modes for people and the planet compared to personal vehicle use, yet oftentimes there are factors that limit participation and safety. The HEAT Lab investigates the barriers and facilitators of active transportation for existing users and non-users. We explore environmental exposures (e.g., heat stress, air pollution, noise pollution, nature elements), built environment characteristics, and social factors that may influence active transportation use and both its perceived and actual safety. Together with community members, municipalities, and transit authorities, we build evidence for policies that support healthier and safer active travel for everyone.
