it doesn't matter for mapping what is commonly understood/interpreted now, 
because they will take care of it in the future  if people use the scheme in 
sufficient numbers to make it worth the implementation.

and now with 1 landing in the central steps please, and step_count. How can we 
avoid the impression that there are now 6 escalators rather than 2?

And then I would like to tag that the separating wall between the downwards 
escalator and the steps is 1,20 m but between the centre and the upwards 
escalator it is only 1,00 m 
This is very easy and intuitive with ways for each escalator and the walls, and 
it gets quite complex and opaque with implicit geometries and nested tags.

how would you represent the landings in this model? IMHO when there is a 
physical separation it's different to "lanes", and the approach of indirectly 
mapping features leads to more complexity that could easily be avoided with a 
different representation.

Not at least you will create problems for the rendering in detailed zoom levels 
because you don't know where the only way has been drawn (center of which way, 
all parallel stairs together? The central one (think of 2 escalators with one 
or 2 stairs in the middle and different widths)).

Hi Tobias,

Would you be able to give me an example for the use of the tag?

Say for steps running in parallel with two escalators (running up/down)?

Thanks,
Bjoern

As the co-author of the conveying proposal, I'd like to offer an 
alternative here. The proposal already mentioned the conveying:lanes 
syntax as a possibility for mapping parallel escalators, and escalators 
parallel to regular steps.


I think that doing it that way has significant benefits for rendering 
(i.e. avoid the inevitable overlapping ways and gaps), and the approach 
might be extended to other highway=step attributes where the need arises.

Yes. An escalator can be used as a steps even if it is defect.
highway=steps is a well known tag while highway=escalator is both
deprecated/out of date and not well known and therefore not supported by
much data users.

Yes, you draw to parallel ways. One way gets conveying=yes, the other
one not (or conveying=no).

Best regards

Michael

no

as they are necessarily separated , you need 2 ways for a decent 
representation. Also step_count will likely be different, and the steps will 
typically have landings, unless they are very short.

[Tagging] steps parallel to escalator

[Bjoern Hassler]

Hello all,

A few questions about steps/escalators:

(1) Should an escalator always have "highway=steps"? I.e.
highway=steps
conveying=yes
(see http://wiki.openstreetmap.org/wiki/Key:conveying ).

(2) How would I tag steps that run in parallel to an escalator? Can this be
done with one way only? If so how? Or would I need two ways? In my opinion
it would be best to do it with one way, if they really are part of the same
construction.

There's a small amount of discussion here:
http://wiki.openstreetmap.org/wiki/Talk:Tag:highway%3Dsteps

Could the outcome of the discussion be added to
http://wiki.openstreetmap.org/wiki/Tag:highway%3Dsteps ?

(I've not been able to register for a wiki account - somehow there's a
captcha required, but no captcha visible. If somebody can tell me how to
register, I can add it.)

Thanks!
Bjoern
