A new study, part of the Atlanta Commuter Exposures (ACE) Study, has assessed on-roadway in-cabin particulate pollution (PM 2.5 ) collected from scripted rush hour commutes on highways and on non-highway side streets. Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period.
