The acoustic camera trial is complete and preliminary indications are that the device can identify individual vehicles in certain circumstances and assign noise levels to them, but further development is needed to improve accuracy.

The technology has the potential to identify excessively noisy vehicles; however, there are still difficulties in measuring noise in an uncontrolled environment to be overcome. As a result, further development and testing will be required before it could be recommended for wider scale roll out, especially if the camera is to be deployed in urban environments where complex traffic and environmental scenarios are common.
