Highlights A strategy for navigating heavy-duty trucks through communities is developed. The strategy reduces community-wide exposure to truck’s tailpipe emissions. For one example community, low exposure route could be found in 23% of the trips. On average, it would reduce PM2.5 and NOx inhalation by 50% and 50%, respectively.
Abstract This paper describes a strategy for navigating a heavy-duty diesel truck through communities in a way that lowers the total exposure of community members to tailpipe emissions from the truck without significantly increasing travel time. This low exposure route was evaluated against the baseline route that truck drivers would normally take for a number of truck trips in two selected communities in Southern California. The evaluation results show that, for up to a quarter of the truck trips, it is possible to find a low exposure route that would reduce community-wide exposure to the truck’s tailpipe emissions by up to 50% on average, with an average travel time increase of no more than 5%. These results demonstrate the potential of the exposure-based vehicle routing strategy to mitigate the air pollution impacts of diesel trucks in disadvantaged communities that are overburdened by truck traffic.
