摘要
通过不同车辆流模型下道路旁绿化带对交道噪声衰减的计算及模拟,研究了城市道路边绿化带对交通噪声的衰减,并用实测对计算和模拟结果进行了检验。还通过主观反应调查并运用模糊隶属度原理进行分析计算,论证了绿化带对交道噪声引起的烦恼度心理影响有一定改善。并通过实验数据论证了这一改善在数量上约与绿化带对交遁噪声的实际衰减相当。
The attenuation of traffic noise of greenbelts on road sides is studied by different models of traffic flow.The results of calculation and computer simulationre tested by practical measurements.By investigation of subjective response to traffic noise and calculation on principle of fuzze subordinate grade, it is proved that the affects of annoyance caused by traffic noise on psychological response can be improved by greenbelts.
