Some considerations of traffic noise generation under interrupted flow conditions.

Reliable techniques are being used by Australian State Road Authorities at present for the prediction, measurement, assessment and control of road traffic noise.However, these techniques are all based on the assumption of freely flowing traffic conditions.A brief outline is given of a descriptive and predictive model, which is both theoretically and empirically based and which is currently being developed and evaluated. From there, a consideration of the noise generated by platoons of vehicles operating under both interrupted and free flow conditions is presented.
