The acoustic camera trial is completed and the results are awaiting publication. 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.
