为了进一步评价重型车辆数和最高水平噪声事件对公路交通噪声所致烦恼程度影响的重要性,作者对5个国家(挪威、瑞典、丹麦、瑞士、芬兰)的18地区进行了调查。所选地区代表了典型交通模式:从郊区到高度繁忙地区、主要通道、高交通流量的城市街道。大多数地区车速限制为50公里/小时,这些地区的交通有完全通畅与阻塞的差异。测 In order to further evaluate the importance of the number of heavy vehicles and the highest level of noise events affecting the level of annoyance caused by road traffic noise, the authors investigated 18 regions in 5 countries (Norway, Sweden, Denmark, Switzerland and Finland). The selected area represents a typical mode of transport: from suburbs to highly bustling areas, main thoroughfares, urban streets with high traffic flow. In most areas the speed limit is 50 km / h, and the traffic in these areas is completely unobstructed and blocked. Measurement
