Traffic Calming Assessment Finds Noise Levels Comply

Shoalhaven City Council recently installed six new traffic calming “raised threshold devices” across the City with funding assistance from the State Government under the “Pedestrian infrastructure around schools” program. The facilities have 4 metre long platforms and 1.5 metre long ramps at either side.

To address local resident’s concerns about the change in noise environment, Council has undertaken a comprehensive noise impact assessment on the devices installed at Moss Street, Nowra, Golf Avenue, Mollymook and Cambewarra Road, Bomaderry.

The noise impact assessment found that by reducing traffic speeds around the raised threshold devices, overall noise levels have dropped slightly around the devices. However, with the apparent change in vehicle speeds, an increase in engine and drive train noise has been introduced as vehicles accelerate away from the devices. As a result, while the overall noise levels are lower the character of the environment may be perceptibly different.

The measurements indicated that the noise following installation of the devices does not have annoying characteristics and the noise levels comply with the applicable criteria and thus there is no exceedance of the applicable noise criteria, no annoying characteristics or noise increase identified by the before and after noise measurements.
