ASSESSING THE IMPACTS OF ROAD TRANSPORT ON AIR QUALITY

This article describes a research programme, being undertaken by the Central Laboratories of New Zealand, to develop motor vehicle air pollution models better adapted to conditions in New Zealand. The first stage was to evaluate two transport network models, POLDIF from CSIRO, Australia, and CALINE4 from the Department of Transport, California, USA. They were found to be suitable as screening models to indicate areas of higher pollution, but tended to underestimate observed pollution levels by a factor of up to 2.0. The second stage was to determine emission rates of New Zealand vehicles. Emission measurements were conducted in two road tunnels in the city of Wellington, using the 'tunnel study' technique. Examples of figures for the emission rates of carbon dioxide and nitrogen oxides are quoted, and the study is to be extended to emissions of aromatic hydrocarbons and particulates. The third stage is the development of a pollutant dispersion model.
