Air pollution in cities, especially in existing urban canyons, poses a global significant long-
term health risk to the urban population, and urban planners are faced with the challenge of …

This paper is investigated the comprehensive study of the nitrogen dioxide pollution
distribution in a specific street in Almaty city, Kazakhstan. It was given a generalized …

In this paper, it was considered the numerical modeling of concentration propagation using
solid barriers and porous barriers of different heights in an idealized urban canyon to protect …

People around the world increasingly live in urban areas where traffic-related emissions can
reach high levels, especially near heavy-traffic roads. It is therefore necessary to find short …

Viaducts built in cities all over the world can increase their traffic capacity. Yet whether
specific dispersion and reduction strategies for traffic-related pollutants, such as ultrafine …

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 …

Recent research has suggested that noise barriers have significant impacts on near-road
automobile emissions reduction. T-shaped noise barriers have better performance on …

Apart from the aerodynamic performance (efficiency and safety), the wake after an on-road
vehicle substantially influences the tailpipe pollutant dispersion (environment). Remote …

Abstract The US Environmental Protection Agency (USEPA) introduced the RLINEXT
modeling feature in the latest versions of AERMOD (since version v21112) to predict traffic …

Noise barriers are one of the common solutions to control road traffic noise. Many studies
have also shown that noise barriers cause reductions in near-road air pollutant …
