I, for one, prefer to have the platform node/way and its corresponding
stop_position in 1 stop_area relation per direction of travel or per
platform (in bus stations).
I don't mind adding the shelter, waste_basket, bench,
ticket_vending_device, announcement_board to such a relation.
Then these stop_area relations can be grouped. I started doing this in
stop_area_group, but later on simply started creating a hierarchy of
stop_area relations, as JOSM's validator complained about the
Having said that, I'm not always creating these stop_area relations. I'm
mostly mapping bus stops and routes and if there is no ambiguity with
resolving the correspondance between platform and stop_position/[highway to
be added ot the route relation], then spatial is good enough for me.
For underground features I would probably map all of the stop_area
relations, so it's clear what belongs together. For grouping 2 platforms /
2 stop_positions with the same name that are near to each other, there is
no real benefit in having them all together in stop_area relations either,
what's the functionality of that?
