A comparative study on noise emission models of an individual vehicle, which is a significant part of road traffic noise prediction models at home and abroad, is conducted. Those models are analyzed elaborately in the following aspects:structure and characteristics of these models, noise emission at 7.5 m distance, noise emission difference of various vehicle categories, and noise emission difference between accelerating and steady running conditions. Some suggestions for research of prediction models of road traffic noise in our country are proposed.
