Nowadays, crosswalks are often drawn in an X shape to accommodate pedestrians.
And here we have an entire area designated as a crosswalk.

How do you tag them in these cases?
Also, there’s not even a traffic light here at all, so I want to designate this as a pedestrian zone.
What are your views?

After considering different cases and situations and comparing the OSM wiki, I concluded that the ‘area:highway=pedestrian’ tag is the most similar.
The rationale is that…

• There are too many different pedestrian directions.(건널 수 있는 방향점이 매우 많다.)
• There are no traffic lights and pedestrians can enter at any time.(교통 신호등이 없고 보행자가 언제든지 길로 들어설 수 있다.)
• These attributes are very similar to ‘highway=pedestrian’.

For reference, I’m adding a discussion from the OSM forum.
