摘要
The medium/long term prediction of urban traffic noise and evaluation of noisepollution in "macroscopic" way using computer are new research work in China. Inthis paper, some investigations, including the methods of predicting and evaluatingurban traffic pollution, have been repotted. Models for vehicles’ flow and propagationof noise in urban areas have been set up. Finally, a set of computer programs forthese purposes is given. Models and computer program have been tested in more than70 cities of China. It is proved that they can be used in medium/long term predictionof urban traffic noise pollution in China, and they are also of great values in evalu-ating the extent of urban traffic noise pollution.
