Abstract: Over the last decade or so, there has been increasing concern with the deterioration of living environments in existing urban areas caused by overflow of through vehicle movements, especially regarding the traffic noise. The management of traffic is perhaps the greatest planning problem currently facing local government in the residential suburbs of the Sydney region. The east roseville scheme was the first local area traffic management (LATM) scheme implemented in New South Wales. In this scheme before/ after noise surveys and assessments were undertaken by the state pollution control commission (spcc). The following conclusions regarding traffic noise were presented in the spcc report: the scheme had a dramatic noise impact inside the local area with significant noise decreases (benefits) in some heavy trafficked streets and significant noise increases (disbenefits) in some low trafficked streets. With 'fine tuning' of the scheme, it may be possible to achieve a more comfortable and equitable acoustical environment for residents inside the local area. Traffic control devices become significant noise generators only with aggressive drivers. With 'fine tuning' of the scheme, this may be minimised. The spcc has indicated draft recommended background noise levels for different land use zonings in the environmental noise control manual released earlier this year. The acceptable levels for a residence in an urban area is stated as 45 and 35 db(a) l90 respectively during the day and night while the maximum levels are stated as 50 and 40 db(a) respectively.
