对比分析法国 NMPB 道路交通噪声预测模型与国内常用的道路交通噪声预测模型， NMPB模型与其他模型在应用范围、车辆分类以及传播模型基础架构方面具有一定的相似性，但各个模型的源强预测模型区别很大。本文选取一条典型的城市道路，根据长时间监测观察获取的批量数据，对各个模型的预测结果进行分析，结果表明：NMPB模型预测结果与实测值吻合相对较好；在夜间或者重型车较多的道路上，如使用NMPB模型进行预测，还需要进行适当的修正。

The paper presented the principle and main features of the French traffic noise model NMPB,and compared it with other three models widely used in China. The fundamental difference between them lied in prediction modeling of source intensity;however,the NMPB was fairly similar to other models in terms of application scope,vehicle types and paths of sound travelling. Based on the batch data of traffic noise and traffic flow from a typical urban road ,we evaluated the perform-ance of NMPB and compared the results with those from other models. The results from NMPB were consistent well with the site-measuring values,while for night modeling or for roads with more heav-y vehicles running on,some corrections were still needed for the NMPB model.
