[Tagging] Mapping overlapping Pedestrian areas?

Places where Pedestrian areas overlap are very difficult for me to map and also render very badly.

I was wondering if someone has some suggestions on how to map this area 
https://www.openstreetmap.org/edit#map=19/35.77740/140.31301 <https://www.openstreetmap.org/edit#map=19/35.77740/140.31301>

This is Narita Station West Exit, with a big loop road, with a pedestrian area around it (layer 1) , adjacent to a 2 story bicycle parking structure. 

On top of the structure is a large pedestrian area that overlaps the lower one, as well as the street. (layer 2) 

and up another flight of stairs to the northeast from the 2nd pedestrian level is the actual station (it is all built against a hill) 

between the overlapping ped areas that don’t like to render well, or render as bridges, and with footpath access tunnels through he bike structure for the stairs and elevator, and the lack of a “parking structure” entrance/exit for bike structures, and the lack of a multi-storey subkey for bike parking (only present in presets for car parking - almost every big station has a multi-storey bike parking structure under elevated tracks - even my school has a free-standing two story bike parking structure) makes everything about this place confusing for tagging - beyond what nodes for building edges get shared and not shared, which I’m still struggling with. 

I mapped the overlappign part of the ped area as a way with bridge=yes so it overlaps somewhat corectly, but it doesn’t match the actual area.

Mapion maps it quite well, but they don’t bother to map the ped areas on the ground whatsoever. the color shift is to represent different address blocks.

any advice for:

- dealing with the overlapping ped area that doesn’t play well with others

- dealing with shared nodes between the layers when they share a common wall, but not common height

- dealing with bicycle parking as a multi-storey structure with entrances similar to a car parking garage (but absolutely not for cars). Are the car subtag values also valid?

Thanks for your help in advance.
