The study area (c) is situated in the south east of the Federal State of Brandenburg, Germany (b). The mapped road network consists of four road types (black line: a-road, black dotted line: state road; grey line: district road; grey dotted line: parish road). Based on official and additional vehicle counts we pooled a-road and state road to high traffic intensity roads and district road and parish road to low traffic intensity roads. Settlements are displayed in red.
