Air quality management and the role of transport planning and control

This study contains an assessment of air pollution levels in Trafalgar Road, Greenwich. This is a congested road on a main route into central London, which has achieved notoriety since its residents took legal action in an attempt to restrict traffic. The four types of dispersion model used in the assessment are briefly described. All four models show that there is a likelihood that air quality standards for a number of pollutants, particularly:PM10, will be exceeded in the vicinity of busy congested roads in London. Zones where standards are exceeded are restricted to regions within 10m or so from the road. Any assessment has to take account of concentrations on a very fine scale (at distances of 10m from a road).
