Proposal
A virtual highway is a way that doesn't exist as a visible feature in the world but is or can be used by people.
Rationale
- Routers can rely on a possible route that a human has manually created and approved thus areas could be ignored for routing purposes.
- The linear (highway) graph isn't disturbed by two dimensional elements like area=yes
- Creating a separate highway tag instead of using existing ones has the advantage that it can be rendered or routed independently.
Examples
- Visualize an area with additional ways so that it is easier to spot a possible way to walk or cross a square or area.
- Mark ways that have to be used although they aren't visually present in the real world.
- Help for blind routing for crossing areas (squares) when there are no guiding lines available. (Routing with voice direction).
- How people commonly walk on a square or area.
- Walking suggestion or shortest way to cross or access an area.
- Mandatory virtual paths in religious or cultural context.
- Squares that can't be walked on freely although there is no visual distinction.
- Sacral buildings that are approached in a certain way for religious reasons, although it would be possible to move freely.
Tagging
can be refined with the existing access=* or any other related highway tag.
Alternative
M!dgard suggested using highway:virtual=pedestrian/cycleway/unclassified/... instead of defining access restrictions for each way. See the talk page.

ways
Rendering
A separate highway tag will enable an own rendering style if desired. Default it will not be rendered.
