Module documentation[view] [edit] [history] [purge]

This module is used by Template:Infobox road (via Module:Infobox road), but can be used outside of the infobox. Also see Module:Road data/browsetable which can serve as a container for the output produced by the module.

This module powers many of the templates in Category:Browse templates. The unified documentation Template:Browse template documentation exists for those templates.

The above documentation is transcluded from Module:Road data/browse/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (edit) pages.
