Main roads 2022 (EU obligation)

Digital nationwide dataset of the relevant road network, which is used to calculate the 2022 noise maps according to the EU Ambient Noise Directive (2002/49/EC, 34). BImSchV) was used. The roads are assigned to the road class and the average daily traffic. The geometry is intended to represent the respective middle axis of the road and is adapted in its detail to the acoustic requirements and the modeling. The sections of the agglomerations of Hanover, Hildesheim, Braunschweig, Osnabrück, Oldenburg and Göttingen are not part of this data set, this also applies to the sections associated with the federal state of Bremen.本数据集为全国范围内的相关路网数字化数据集，用于依据欧盟《环境噪声指令》（2002/49/EC，第34条）及德国联邦污染防治法（BImSchV）计算2022年噪声地图。 所有道路均已按照道路等级与日均交通量完成分类标注。 数据集的几何要素用于表征对应道路的中心线，其细节精度适配声学计算需求与建模要求。 汉诺威、希尔德斯海姆、不伦瑞克、奥斯纳布吕克、奥尔登堡及哥廷根的都市区路段，以及与不来梅州相关的路段均不属于本数据集范畴。
