| 摘 要： | 针对当前我国道路交通噪声预测中应用得极为广泛的两种模式:我国交通部推荐的预测模型和美国联邦公路管理局(FHwA)公路噪声预测模型在进行预测时的比较研究.通过比较分析了FHwA预测模式和交通部预测模式在杭甬高速公路不同条件下的预测结果,并对预测结果和实测结果进行预测精度的比较,得出FHwA预测模式和实测符合较好.

| Abstract: | There are two widely used models for predicting noise levels in transportation. One is recommended by the Chinese Transportation Ministry. . The other is recommended by the united States Federal High Way Authority( FHWA). This thesis compared the above two models. By using both the Prediction Models from Transportation Ministry and the FHWA models, the prediction results were analyzed for Hangyon high Way at different road conditions. The prediction results and the actual results were compared and the accuracy of prediction were assessed. It was found that the FHWA model gave a more accurate prediction. |
