基于交通噪声的交通量测量方法研究与实例分析

Research of Measurement Method and Empirical Analysis Based on Traffic Noise and Traffic Volume

在提取车辆噪声信号特征的基础上,利用互谱声强测量分析和spss统计分析等手段,提出基于车辆噪声信号的交通流特征参数检测技术,在对检测数据进行数据统计与回归分析的同时,得出交通流与交通噪声间的关系,为提高交通流检测技术水平提供理论基础和实践基础。

Based on withdrawing the noise signal characteristics of vehicles and by the method of cross-spectral sound intensity analysis and SPSS statistical analysis, the technology of traffic flow characteristic parameters based on signal of vehicle noise was proposed. At the same time of the data statistical and regression analysis of the detection data, the relationship between traffic flow and traffic noise was also proposed to provide the theoretical basis and practical basis to improve the detection technology level of traffic flow.
