| 摘 要： | 根据7条珠江新城主要道路的交通流实测数据，结合标准ISO 9613-2噪声计算模型，采用不同的道路分割精度模拟出整个珠江新城的交通噪声分布，以分析不同道路分割精度对交通噪声模拟的影响。另外，在珠江新城选取8个地点进行噪声值实地采集，以评估噪声模拟值与实测值的误差。结果表明，以接收点为中心，扫描角度不大于5度的道路分割方式对交通噪声模拟效果较好。

| Abstract: | The computational model based on standard ISO 9613-2 for noise attenuation is used to simulate the noisedistribution in Zhujiang New Town of Guangzhou with different refinements of road segmentation according to themeasurement data of traffic flow of seven main roads in this area. The impact of different refinements of road segmentationon traffic noise simulation is analyzed. For each refinement of road segmentation, eight points are selected to measure thenoise level for error evaluation. The results show that the road segmentation with the scanning angle centered at the receiverless than 5 degree is appropriate for the traffic noise simulation. |
