Researchers from Imperial College London used airflow modelling techniques to study the movements of roadside particulates and develop a solution to minimise the exposure of pedestrians on adjacent paths. Air pollution, particularly in high-density urban areas, is a growing health concern around the globe and is estimated to be responsible for around 30,000 deaths in the UK alone each year. Imperial researcher Dr Tilly Collins became acutely aware of the extent of the issue while watching her child playing netball in a school playground alongside a busy London A-road.
