A field study of factors influencing the concentrations of a traffic-related pollutant in the vicinity of a complex urban junction

This paper, which arose from an EPSRC platform grant (GR/T26610/01), found that pollution concentrations are highly spatially variable within complex urban geometries, and that synoptic wind patterns, traffic queue location and building topologies all play a role in determining where pollutant hotspots occur. The research confirmed the presence of different dispersing airflow regimes that had previously only been identified in wind tunnel and numerical modelling work. The contribution of this paper to the field is evidenced by citations from researchers in the UK, Argentina, France, Germany, Czech Republic, USA and New Zealand, among others.
