Motor vehicle emissons inventory modelling

Motor vehicles are a known dominant source of anthropogenic pollution in the atmosphere, with motor vehicle exhaust acting as a major source of common pollutants including hydrocarbons, volatile organic compounds, carbon monoxide and nitrous oxides. In large quantities, these pollutants are detrimental to human health and the environment thus it is important to have an accurate Motor Vehicle Emissions Inventory Model, to keep track of motor vehicle emissions in the complex state traffic network. An emissions inventory is used to determine community exposure to, and the impact of, pollution, and is crucial for the long-term management of the environmental, social and economic risks associated with air pollution.

Work on modelling Australian motor vehicle emissions, with a particular focus on South Australian emissions, is currently being conducted. We are examining the effects of emissions rates of vehicle speed distributions on different road types such as Residential, Arterial, Congested and Freeway. Using the newly collected NISE-2 Australian data, collected as part of a major study periodically commissioned by the Australian government, we are interested in examining the effects on emission rates of different vehicle speed distributions and conducting sensitivity analysis to develop strategies for exposure reduction. To date, little research has been conducted on the NISE-2 data, due to its recent addition to the national inventory, propelling this research project to the forefront of an exciting new era in motor vehicle emissions modelling.

This project commenced in 2011 and is currently ongoing. The research is being undertaken in conjunction with the Environment Protection Authority (South Australia).
