Inequity Identification Tool (IIT) Air Cost
Description
This file contains the road segments from FHWA's HPMS dataset with estimates of the cost of air pollution from the traffic on that segment. The cost of air pollution is estimated using a combination of traffic volumes and speeds from FHWA's HPMS, the emission rate of PM2.5 from EPA's MOVES, the dispersion rate and pollutant concentration from EPA's AERMOD, the per unit health costs from a series of studies cited in EPA's COBRA, and the population affected from the US Census ACS 2019. The resulting cost per road segment is transformed into cost per 1/10 mile length of roadway and binned into 7 different categories to reduce the file size.
