Inequity Identification Tool (IIT) Noise Cost
This file contains the road segments from FHWA's HPMS dataset with estimates of the cost of noise pollution from the traffic on that segment. The cost of noise pollution is estimated using a combination of traffic volumes and speeds from FHWA's HPMS, the noise produced through FHWA's TNM3.1, the number of households affected from the US Census ACS 2019, and the per unit noise costs from a series of studies cited in FHWA's ECAT. 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.
