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

Presents outcomes from the largest series of field dispersion studies ever carried out in a UK city (http://www.dapple.org.uk/). Establishes the importance of several urban features on pollution hotspot development e.g. build-up of pollutants within traffic controlled intersections and on the leeward/sheltered side of street canyons. Thus highlights the need to reduce congestion related emissions to meet European air quality targets. Following press coverage has also led to advice to pedestrians/cyclists on reducing daily commute exposures. Data was shared with Transport for London and also used for validating pollution dispersion models developed to assess pollution management strategies (e.g. at Imperial College).
