Reduction of Traffic-Related Pollution through Green Infrastructure Solutions

This paper investigates the effect of green infrastructures in mitigating air pollution in urban environments. This complex issue needs a thorough examination of trafficrelated emissions and the atmospheric dispersion of chemical species. A macroscopic second-order model is employed to simulate traffic conditions, followed by a microscopic approach to estimate emission levels. Finally, partial differential equationsbased atmospheric dispersion, driven by chemistry ordinary differential equations for particulate/nitrogen oxides/ozone interactions, handles vertical transport under varying conditions. Numerical results show that different configurations of green barriers yield varying pollutant concentrations in metropolitan regions.
