Abstract
A digital simulation method of urban road traffic noise has been developed suitable for use in China. The simulation is based on local environmental standards, vehicle types and traffic conditions. The result indicated that the simulation was accurate to 0.6 to 1.4 dBA at locations near the road carriage way and within the housing estate, at some specified spot with results in good agreement with measurements, which is comparable to the CRTN model. An integrated noise predicting and evaluating system was developed to provide general functions for noise simulation and an additional tool for noise design. Application of this system offered improvements in the efficiency and accuracy of traffic noise assessment and noise design. Finally, relationships were established between the equivalent level, traffic flux, and the main noise level percentiles, with results in good agreement with those of other authors. We can also conclude that city noise can be usefully studied by classifying the streets according to their use.
