An assessment methodology for pedestrians PM2.5 exposure associated with crossing traffic hotspots is presented. The quantitative PM2.5 exposure concentration reduction effects of at-grade intersection design with stretched segment, pedestrian bridge and left-turn prohibition are estimated using a new US Environmental Protection Agency general emissions model: a multi-link dispersion model based on the AERMOD model. The results of the case study show that intersection design using a stretched segment has a reverse effect on pedestrian PM2.5 exposure, while the left-turn prohibition and the pedestrian bridge are environmentally friendly options with lower PM2.5 concentrations. In order of effectiveness, the intersection design types can be listed as pedestrian bridge, left-turn prohibition and stretched segment, based on the pedestrian PM2.5 exposure index. This study proposes guidelines and tools that road/intersection designers and engineers can use for quantifying environmental impacts. It also shows that design configurations have the potential to mitigate air quality impacts from traffic.
