A platform can be a pole, or a shelter, or a dock, or a boarding platform

of transport.

Anyway, the attempt to clear up the distinction between mapping stops next

 be done twice, which is a total waste of time.

The stop_position is where the bus, train, etc. stop on their way, while
the platform is where passengers will be waiting to board. Both features
are distinct and serve different purposes in real life, so why not store
both in OSM ?


 My problem is that when I'm adding stops as nodes in Germany and put the
 details on there, those nodes get cleared/removed. I can reinstate them,
 but it won't stick, so it's futile to do so.

 At some point I thought that starting to include the platform ways to the

 mapped on the stop_position nodes.

In theory, redundant details on the same stop should be put in the
stop_area relation in order to reduce redundancy.

The stop_area relations combine both directions, That's useless. I don't
 know who abolished stop_area_group, But what good are these stop_area
 relations if they don't help to relate an individual platform with a
 stop_position?

I am the mapper. I use the processing to assist me, like a tool. I also try
to map them all in the same way for consistency. The problem is that
apparently there was still room for interpretation in the 'version 2' of
the public transport scheme.

What I see happening in Germany is that information is duplicated
needlessly. Moving it to the stop_area relation would be a logical step,
but information doesn't cascade through like that in OSM. In Belgium every
stop has its own ref, and of course if you calculate a route_ref from the
schedules this will not always yield the same result for both sides of a
street.

I don't see what attributes of a stop/platform could be dependant on the
direction, do you have examples ?
Anyway, if there really is different informations on each stop, it is okay
to put them in the nodes/way and only put data applicable to all stops in
the stop_area in the stop_area relation.

This is the usual way of using relations : aggregate common data between
multiple features in a relation containing said features, and if there is
differences between these features put the tags directly on the nodes/ways.

To me it's logical to put all those ref, network and operator tags in the
stop_area relation, not on the nodes or ways. The relation is the only
element that describes the bus stop completely. If you only put the ref and
operator on the platform, the stop position is missing.

But if mappers in a city agree that they don't need stop_area relations,
they can put ref and operator tags on platforms, or stop_areas. I think
this can be reasonably flexible, but only between networks, or countries.

Also, putting waste_baskets, benches, flowers, toilets, cafes and other
things in the stop area relation is unnecessary. Who decides if a cafe is
near enough to be in a stop_area? What do they have to do with public
transport? Only the stop_position and platform are needed. But I'm not
going to remove those from a stop_area relation, they don't hurt.

 What I'm doing comes down to mapping the poles. stop_positions could be
 shared for stops that are exactly across one another.

 I guess there is no choice but to rewrite the script(s) in order to cope
 with all variations of possible ways to map. Or else simply give up on it
 and move on. Not sure which I will choose.

 It would be nicer if we were able to come up with a totally consistent
 version 3 of mapping PT, but what I see, is we're moving in different
 directions. What is logical to me, apparently isn't for the rest of the
 world. What I do know is that I'm not going to be spending the next 2 years
 to make sure all the stop_positions (5 for a small country) are
 present. They're simply not important enough for that. I add them here and
 there and consistently for the terminal stops.

 What I want to focus on at the moment is to get all the itineraries in ,
 the routes and their variations. To me that seems like a better use of my
 time.

I tend to add the waste_basket that clearly 'belongs' to the bus stop, the
bench, the shelter, the ticker/departures screen in as well. Most of the
time they have a style you don't see elsewhere. Never occurred to me to add
toilets or flowers or pubs though.

But do we agree a stop_area relation is needed for each side of a street?
and a stop_area_group to show that they belong together?
