Effects of Transportation Choices on Commuter Health

The primary project objective is to investigate how an individual's choices influence personal exposures to traffic-related air pollutants (TRAPs) and the corresponding acute health effects. TRAPs are a complex mixture of particulate and gaseous pollutants that vary considerably spatially and temporally. There is increasing evidence that TRAPs inflict a broad range of deleterious health effects in both health-compromised and healthy individuals, and it has been reported that traffic pollutants may cause up to half of all air pollution-related mortalities. Despite the burden from such widespread, involuntary exposures, few studies have examined the magnitude of personal exposures due to commuting exposures. Most commuters travel to and from work during two peak travel periods, which occur during weekday mornings and evenings. Public transportation, bicycling, and walking have been promoted as ways to reduce air pollution by reducing the vehicle fleet, yet few studies have examined how exposures are modified due to an intentional change in the time of commute or the subsequent health effects.
