EFFECTS OF ROAD TEXTURE ON TRAFFIC NOISE AND ANNOYANCE AT URBAN DRIVING SPEED
This paper describes research which has found that there is an insufficient allowance being made for road surface effects on traffic noise in the New Zealand urban areas where vehicle speeds are typically 50 km/h. Therefore, low noise road surfaces could have much greater benefit in reducing community annoyance with noise in urban areas than was previously thought. A vehicle cruise-by technique, which captures both the noise level and a spectral distribution of the noise from test vehicles and samples of actual vehicles within vehicle streams, was used to measure the noise from a range of road surfaces. It was found that, at 40-50kmph, when compared to dense graded asphalt, the most commonly used road surfaces (the chip surfaces) may be 3 to 6dBA noisier for cars, and 0 to 2dBA noisier for trucks. These effects are much larger than were anticipated by commonly used road noise models.
