Daytime road traffic noise exposure

The map shows the daytime road traffic noise to which the population is exposed. The data is based on area-wide model calculations (sonBASE). The Swiss road network included in this calculation covers approximately 45,000 km. The traffic data for road traffic was determined on the basis of the NPVM. To this end, approximately 4,000 traffic counts from 2021 were processed, which were carried out by the federal offices ASTRA and FSO as well as by the cantons and cities. The calculations are not legally binding. The only legally binding data relating to noise exposure and noise improvements are those issued by the responsible enforcement authorities, i.e. for motorways the Swiss Federal Roads Office (FEDRO), and for main and other roads the relevant cantonal authorities.

本地图展示了人群暴露的日间道路交通噪声情况。该数据集基于全域模型计算（sonBASE）生成。本次计算纳入的瑞士公路网络总长约45000千米。道路交通流量数据以NPVM为依据确定：为此，研究人员对2021年开展的约4000次交通流量计数结果进行了处理，此类计数工作由瑞士联邦交通局（ASTRA）、瑞士联邦统计局（FSO）及各州市政府共同完成。本计算结果不具备法律效力。唯一具有法律效力的噪声暴露与噪声改善相关数据，由相应执法主管部门发布：高速公路相关数据由瑞士联邦公路局（FEDRO）出具，主干道及其他道路的相关数据则由对应州市主管部门发布。
