Based on the recent valuable feedback from the global community, I would like to propose below a few changes to the minor road classifications wiki that I believe will solve the most common issues:
A) In a nutshell, the proposal revolves around limiting:
highway=residential to road segments found only within residential areas (populated areas typically found under landuse=residential inside cities, towns and rural settlements) and giving the public access to one or multiple residences.
highway=unclassified to roads only with a significant thru-traffic function (the equivalent of “quarternary”, used to reach a settlement or another road of higher or equal importance)
highway=track to road segments with only the function to access the surrounding land (fields, forest) that do not give access to any particular places.
highway=service for all other minor use-cases e.g.
- roads inside estates (driveways, attractions, factories, commercial areas, parks…)
- roads leading to places outside residential areas (temples, lodging, farmhouses, remote residences, attraction, dam…)
Note: major road classifications (tertiary+) have already been covered in the wiki.
B) This proposal would solve these common issues:
highway=residential used for anything giving access to buildings (Grab, Facebook). We would have now a clear distinction between
unclassified. Since the correct classifications can often be known with ground information, it will of course not solve the issue of remote mappers choosing the wrong classifications. But encouraging them to use
highway=roador not changing them can be a solution.
highway=unclassified used for non-significant roads (local mappers). There are currently too many
unclassifiedroads making the general public network hard to visualize and interpret for routers. I believe this is due to the misconception that
serviceroads can only be private. Only tagging the significant thru-traffic ones with
unclassifiedand the rest with
servicewill help tremendously.
highway=track used for anything unpaved. Many of these dirt tracks actually give access to farmhouses, and temporary residences and deserve (Grab) a higher classification like
