广州市道路交通噪声现状分析

Analysis on the Traffic Noise Situation in Guangzhou

本文运用数理统计的理论和概率论对监测数据进行归纳、整理、分析。建立了交通噪声等效声级与车流量变化的数学模型,从理论上说明了广州市道路交通噪声年变化趋势的动态规律;给出了广州市道路交通噪声的时间分布、空间分布规律以及交通噪声各评价量与车流量各成份的作用关系,为广州市道路交通噪声防治对策提供依据。

Using the statistic and probability theory,this article summarized and analyzed the measurement values, established a maths model equivalent sound level and the vehicle flowrate and described the dynamic trend of the annual traffic noise variation in Guangzhou. The article also gives the regulation of time distribution and space distribution, relationship of various evaluation of traffic noise and the component of vehicle flow. This study supplied an important basis for protecting and monitoring traffic noise in Guangzhou.
