The restriction:bicycle=* tag is used to define specific turn restrictions for bicycles at intersections. This includes guidelines on how bicycles are permitted to turn, including the concept of a "Grünpfeil" (green arrow) commonly used in German-speaking countries.
A "Grünpfeil" is a traffic signal that allows right turns (and sometimes left turns) for cyclists even when the main traffic signal is red. This special signal is often encountered at intersections and is designed to facilitate the flow of bicycle traffic while ensuring safety.
The restriction:bicycle=* tag provides valuable information to both cyclists and navigation software, helping them understand where and how bicycle turns are allowed at intersections.
When to map
There are a number of important things that need to be taken into account when creating a turn restriction.
- There may be several turn restrictions at a junction, represented by separate relations.
- Don't map turn restrictions that are the default for a given jurisdiction and are not signed. It is much better to ensure that routing engines embody the regional rule rather than mapping every occurrence as a turn restriction. This applies particularly to unsigned U-turns in Brazil, where using turn restrictions will require hundreds or thousands of restrictions and micro-segmentation of all roads which in turn make editing data hard.
