This paper investigates the influence of viaduct, noise barrier, and the ratio of leeward and
windward building height (H1/H2) on flow regime and particulate matters (PM) dispersion in …

Traffic-related air pollutants are a significant public health concern, particularly near
freeways. Previous studies have suggested either soundwall or vegetation barriers might …

More evidence has shown that exposure to particulate matter (PMs) within urban streets
increases adverse health risks, and vegetation barriers have the potential to improve near …

Green-blue-grey infrastructure (GBGI) offers environmental benefits in urban areas, yet its
impact on air pollution is under-researched, and the literature fragmented. This review …

Trace elements emitted by road transport cause long-term contamination of road soils. This
study showed the effect of the noise barrier on the spatial distribution of metals in soils at the …

The noise reduction effect of noise barriers has been extensively studied, but the effect on
pollutant dispersion remains unclear. A computational fluid dynamics (CFD) simulation is …

People of different races and ethnicities are equally likely to live and work near Louisville's
highways—a sign that exposure to roadway pollution is not racially differentiated. Exposure …

Modeling analyses were developed to evaluate near-road PM 2.5 concentrations predicted
by the AERMOD dispersion modeling chain under real-world conditions, and to assess the …

Communities located in near-road environments experience elevated levels of traffic-related
air pollution. Near-road air pollution is a major public health concern, and an environmental …

The trend of urbanization has attracted increased attention towards urban areas around the
world. Central business districts (CBDs) serve as the core of commercial activities of urban …
