Traffic area

In Traffic areas are those areas of land developed to serve road, railway and air traffic. These include driveways, lay-bys, market squares and pedestrian areas, as well as railway stations and airport terminals. In particular, land for traffic is generally sealed and includes accompanying green space. Not included are minor paths, decommissioned stretches of track as well as harbours (onshore harbour facilities are defined as industrial and commercial areas; the harbour basin is assigned to the category water).

For roads and railway track, generally modelled as lines in the ATKIS data set, estimates for width (or a standardized value) are used to calculate spatial extent. This means that traffic area is more narrowly defined than in other data sets which, for example, include waterways, lakes and seas as well as the designated airspace.

Regionally differentiated migration effects may occur as a result of the transition from the ATKIS Basis-DLM (Version 3.2) to the AAA-Model (Version 6.0) ). In the case of traffic areas, this is particularly true of roads and railway tracks, whereas air transport is less affected. For example, roadway greenery in the centre of a roundabout is explicitly captured within the new AAA model, thereby increasing total traffic area.
