Abstract :

Commuting accounts for one of the highest daily air pollution exposure periods for workers in the U.S.; however, exposures vary greatly depending on transportation mode. In this study, we compared commuters' (N = 433) perceived versus actual air pollution exposures across six modes of commuting in Salt Lake City, Utah. Commuter perceptions of exposure were compared with measured (actual) fine particulate matter ([PM.sub.2.5]) exposures. Comparisons were made using the Wilcoxon signed-rank test. Participants ranked active modes of commuting (walking and bicycling) as being less exposing to air pollution than automobile and public transportation modes, while actual exposures indicated that walking and bicycling yielded the highest exposures (p
