While California has made tremendous progress in reducing vehicular emissions,evidence of the dangers of near-roadway pollutant exposure is growing; highlighting the need to ensure that implementation of Senate Bill (SB) 375 is consistent with ARB’s criteria and toxic pollution exposure reduction policy goals. The objective of this study is to characterize pollution levels at various transit stop environments in southern California, with a focus on features in the built environment, such as building setback and height. This will be accomplished through pollution measurements, meteorological measurements, and modeling. The results of this project will be a rich data set characterizing transit stop environments and a predictive model for a complex urban landscape. This information may provide transportation and urban planning decision makers with the tools they can use to guide everyday decisions that impact exposures in these environments.
