Abstract

Three alternative models of traffic noise prediction have been applied to two major roads in a large provincial city in Australia. The roads are segmented into links and the environmental capacity of each link is determined. Both one-hour and 18-hour noise levels are used for capacity estimation. This allows a rational comparison of the ease of use, data requirements as well as limitations of alternative traffic noise models. The sensitivity of the environmental capacity to changes in setback distance, traffic composition, traffic speed, and acceptable noise levels is explored. This is useful in the formulation of rational strategies for improving the environmental capacities of roads. The amelioration models should,
