TL;DR: In this article, the authors proposed a topology optimization method based on continuous material interpolation functions in the density and bulk modulus to reduce the sound pressure amplitude in the shadow zone behind a sound barrier.
282 citations
TL;DR: Findings support the notion that solid roadside barriers may mitigate near-road impact and encourage research regarding the mitigation potential of vegetative barriers of other configurations (e.g., greater density, wider buffer).

TL;DR: In this article, a vegetation belt of limited depth (15m) containing periodically arranged trees along a road is numerically assessed by means of 3D finite-difference time-domain (FDTD) calculations.
167 citations
TL;DR: In this article, a study was designed to assess traffic emission impacts on air quality near a heavily traveled highway, and the results indicated that the presence of a noise barrier can lead to higher pollutant concentrations on the road during certain wind conditions.

TL;DR: In this paper, the effects of roadside barriers on the flow patterns and dispersion of pollutants from a high-traffic highway in Raleigh, North Carolina, USA were examined using the Quick Urban & Industrial Complex (QUIC) model.
