New rider data shows how public transit reduces greenhouse gas and pollutant emissions

Research published in Environmental Research Letters this week by Daniel Mendoza (UU Atmospheric Sciences), Martin Buchert (CMP), and John Lin (also Atmos. Sci) on net impacts to emissions resulting from UTA transit operations. The researchers used electronic fare collection data to track actual riders’ movements in time and space (anonymized, of course) and then GTFS data to track UTA vehicle movements in time and space. Models of avoided emissions for transit riders and empirical data on actual emissions shared by UTA enable us to estimate net impacts at hourly time scales over an entire year, and at 200m x 200m grid resolution for the entire UTA transit service area.
