TRB recorded a series of videos in May 2016 that provides information on air quality issues.
Because of the Clean Air Act of 1970 and subsequent amendments, air quality issues need
to be addressed during the highway planning process. This series will help viewers understand
how vehicles and highway projects impact air quality at the regional and project scales.
The videos are available on-demand at no cost.
Here are the slides from the presentations.
