Fahrrinnen

Fahrrinnen is a term found in some German-language planning discussions that refers to a form of cycling infrastructure, but it does not have a single, universally accepted definition. The word combines Fahhrad (bicycle) and Rinne (channel or trough) and is often used to describe a feature that is intended to accommodate cyclists along or across urban streets. In practice, the meaning of Fahrrinnen varies by region and context, and the term is less common in official design guidelines than terms such as Radweg, Radstreifen or Radfahrbahn.

Possible interpretations of Fahrrinnen include a dedicated bicycle lane that is integrated into the road surface or edge, and a groove or trough-like channel intended to guide cyclists along a corridor. The concept can be used in places with limited space, narrow streets, or where alignment with other street elements (such as tram lines or drainage) influences the layout. Because the term is not standardized, it is often necessary to consult local planning documents to understand how a particular project defines and implements a Fahrrinne.

Design characteristics of Fahrrinnen, when used, are variable and depend on local requirements. They may be implemented as a low-profile groove or a clearly delineated lane, and can be combined with specific surface treatments, markings, and drainage solutions. Key considerations include safety at intersections, connections to other cycling facilities, accessibility for all users, maintenance, and how the feature integrates with traffic calmed streets and public transport interactions.
