For the template to work, the transport network (P16) property must be set on the Wikidata entity linked to the article.
Usage
edit{{Highway system OSM map
| highway_system_qid =
| frame-lat =
| frame-long =
| frame-width =
| frame-height =
| frame-align =
| plain =
| text =
| zoom =
| length = <!-- If yes, shows length of each road in the system -->
| stroke-width = <!-- 3 by default, 2 is a good size for dense networks -->
}}
Issues
editSome highway systems will not display correctly if the length parameter is set, because some highway entries will have multiple values for the length property at Wikidata.
