摘要
基于2017年10月—2018年9月期间4处高速公路交通噪声在线监测点的监测数据,将每月的监测数据进行平均化处理,分析了1年的昼间和夜间交通噪声以及交通量的变化趋势,并根据已有研究成果,利用SPSS软件对等效声级与车流量的对数进行了相关性分析,研究表明,车流量的对数与昼间、夜间等效噪声具有较显著的相关关系,因此对高速公路交通噪声具有一定的影响。
Based on the monitoring data that were online monitored at four expressways from Oct.,2017 to Sept.,2018, this paper averaged the monthly monitoring data, and analyzed one-year traffic noises and change trend of traffic volume. Correlation analysis was done on equivalent sound level and logarithm of traffic flow using SPSS software on the basis of existing research results. The results showed that there was significant correlation between logarithm of traffic flow and equivalent noise of daytime and nighttime, it thus had certain influence on the expressway traffic noise.
