Stuart (ORCID # 0000-0003-1229-493) The objective of this study was to model the potential impacts of alternative transit-oriented urban design scenarios on community exposures to roadway air pollution. We used a modeling framework developed previously for the study area that includes activity-based travel demand modeling (Tampa Bay ABM), a dynamic traffic assignment model (MATSim), a mobile-source emissions model (MOVES), a line-source dispersion model (RLINE), and a population exposure estimator to simulate ambient concentrations and population exposure to oxides of nitrogen (NOx) under alternate urban design scenarios for Hillsborough County, Florida. Data from the 2040 transit plan envisioned by the Tampa Bay Area Regional Transportation Authority were added to the modeling system along with reassignment of household residence locations to parcels near to both employment centers and transit stops
