This report provides a summary from a TRB Transit Cooperative Research Program (TCRP) Insight Event about the air quality in transit buses, particularly since the start of the pandemic. Since then, an increased understanding of infectious disease in confined spaces and the role of droplets and particles in transmission has been increasingly important to the bus industry. At this event, senior transportation executives; representatives from federal, state, and local government; and representatives from technology, consulting, academia, and engineering to discuss opportunities and the challenges of implementing air quality control in buses.
