Standards for Modelling Road Traffic Noise in Western Canada
In acoustics, computer modelling can be a great aid in the design process; however, the accuracy and usefulness of the results depends on the prediction algorithms chosen. The U.S. Department of Transportation Traffic Noise Model (TNM) and French standards NMPB 1996 and NMPB 2008 are three internationally used standards for modelling the emission and propagation of road traffic noise. These standards were developed to model traffic noise in their country of origin, but how well do they predict traffic noise in Canada?
Using Cadna/A software, a comparison was made between TNM 3.0, NMPB 1996 and NMPB 2008 based on their ability to accurately predict the acoustical environment around highways in British Columbia. The comparison was made using noise models that were developed for two large highway construction projects near Vancouver, BC. Commissioning field noise measurements and traffic volume data were used to assess the accuracy of each prediction model. The methodology, results and conclusions from this study will be discussed.
