Wild accident accumulation sections

The wild accident accumulation sections (Wuha) were created according to the following rules:

— The maximum distance is 100 m between two accident sites
— The places will be connected together are the distance > 100 m
— The number of connected accident locations (points) is > 5

Only accidents of the following species are taken into account:

— Red deer
— Dam deer
— Sikahirsch
— Deer
— Wild boar
— Muffle
— Deer or deer if unclear,
— unknown species (should occur only at raw data source = police

Status of the calculation is 2022-12-21

Attributes

• ‘wu_poly_id’ — Primal key,
• ‘wuha_laeng’ — length of a Wuha in meters,
• ‘wu_number_’ — sum of wild accidents in Wuha in the three years 2019, 2020 and 2021,
• ‘wu_dichte_’ — Density of wild accidents in Wuha in the three years 2019, 2020 and 2021 (trafficking shell game per km road)
• ‘bez’ — name of the street if available,
• ‘st_astext’ — Geometry for representation in a GIS as WKT,
• ‘standard_deviation_wupkt’ — scattering measure of wild accidents in the section,
• ‘raw data source’ — raw data source: ‘TFK’= animal find cadastre, ‘POL’ = police accident data SH
• ‘Rothirsch’ — number of red deer
• ‘Dam deer’ — number of dam deer
• ‘Sika’ — number of sika deer
• ‘deer’ — number of deer
• ‘wild’ — number of wild boars

The geometry is stored with ETRS89 Zone 32n EPSG code 25832.

In addition to the wild accidents, the basis is a freely accessible data set of the road axis from ATKIS 1:250,000 of the Federal Office for Cartography and Geodesy 2018.
