| 摘 要： | 为了了解我国长期以来使用的两种公路交通噪声预测模型,即美国联邦公路局(FHWA)模型和德国RLS90模型的预测精确性,通过理论分析,比较了RLS90分段模型、RLS90长直线模型、FHWA模型的差异,并通过实际测量值对3种模型的计算结果进行了验证,表明RLS90模型在高速公路交通噪声预测中略优于FHWA模型。

| Abstract: | The FHWA model and the RLS90 model have been used for traffic noise prediction in China for a long time.In order to understand the prediction accuracy of the two models,discrepancies among the RLS90 segmentation model,the RLS90 long straight model and the FHWA model were analyzed theoretically.Field measurement was conducted for verifying the calculation of the three models.The results indicate that the RLS90 model is somewhat superior to the FHWA model in terms of highway traffic noise prediction. |
