and when there are specific reasons why the sidewalk cannot be used, the 
legislation (in some countries at least) let’s the pedestrian use the street. 
One situation is a pedestrian carrying bulky loads which would disturb other 
pedestrians, in this case you have to walk on the road, similar case can be 
made for someone pushing a bike where the sidewalk is not very wide, also these 
pedestrians must use the road.

It seems to me that `foot=use_sidepath` contradicts the 'Don't map
local legislation if not bound to specific objects' principle [^1].
Therefore i think `sidewalk=separate` (or
`sidewalk:[left|right|both]=separate`) should be preferred. This
latter tag is much clearer, can be preciser and has the advantage that
mappers don't need to know the local legislation (i.e. whether the
pavement has to be used or not - although i normally don't see any
reason not to use an existing pavement).

How can they be sidewalks if they are not meant for general walking? 
Also (at least here) those areas have angled kerbs to allow vehicles to

I also wouldn't tag the pedestrian escape tunnels as footways.

This made me open gmail :) There are three questions: I marked them up
in the quote above. My take on 3) It is a tagging error, if
foot=use_sidepath was meant. 2) If foot=use_sidepath was meant, you
still should not change your software, because 1) the tagging might be
correct and not in error, in case there was a sign on the road, that
explicitly prohibited pedestrians from the carriageway, like the wiki
says.

Re: [Tagging] Foot / sidewalk access tagging

[Fernando Trebien]

For routing, foot=use_sidepath and foot=no have almost the same
implications. foot=use_sidepath can be treated as foot=no (complete
prohibition) or sometimes as foot=discouraged (with a very high
penalty instead of a complete prohibition). But foot=no is used in a
variety of situations (and was used for separate sidewalks before a
more specific tag was adopted - so you'll find a mix of old and new
mapping styles), while foot=use_sidepath is specific and can be used
for data validation (e.g. looking for missing separate side
paths/sidewalks). foot=* represents the access permission, [1]
sidewalk=* only describes the attached sidewalks (if any), and there
are regional differences on when to separate the sidewalk from the
main road. [2]

At least the two main routing engines on the main site don't make this
assumption, so I believe it was never what most mappers had in mind.
This intelligence requires either using relations to represent all
parts of a street (adopted in some places, but not most, due in part
to little app support), or naming sidewalks the same as the main road
(proposed, but not widely adopted due to problems resulting from
duplicate street names in rendering and geocoding, and street name
maintenance - remembering to rename all parts when the name changes or
is corrected).

This makes sense to me, but the wiki[1] is somewhat confusing about the
difference between foot=use_sidepath and foot=no:

"This tag, like bicycle=use_sidepath, applies only to roads with a
classification that allows pedestrian use. In some countries it is illegal
for pedestrians to use a road if a parallel compulsory sidepath exists. On
OSM, this can be indicated by tagging the main road as foot=use_sidepath if
the sidepath is mapped separately. This tag should only be applied in
countries that have compulsory footways. Where the main road is explicitly
forbidden, typically by a traffic sign on the main road, whether a sidepath
exists or not, foot=no should be used."

there is another object to describe the sidewalk
if you don't want to load highway=footway/path,
then use this highway=* but the accuracy will be
a little less good since the geometry will be that

the centre of the sidewalk

regarding the alternative :
highway=

it doesn't have the same meaning, it said that a sidewalk

as a datauser agaim, if you don't want to load highway=footway/path,

Re: [Tagging] Foot / sidewalk access tagging

[Mateusz Konieczny via Tagging]

That is an irritating case.

1) with you assumptions it is possible to argue that it refers to case where
there is a separately mapped sidewalk that nevertheless is inaccessible
(some technical/escape route in a tunnel or on motorway?)

2) in practise it is far more likely to be used in case where user tags each
way with own access tags.
Basically
> that foot=* applies to "the whole of the road" including the roadway,
> shoulders, verge, sidewalks, and so forth
has added at the end
> "unless represented with separate geometry"

3) to avoid problem from (2) foot=use_sidepath was invented to mark
"yes, on carriageway you cannot walk, but you can walk on separately
mapped sidewalk"

---

practical advise:

- if there is no separately mapped footway then sidewalk=separate
is wrong and should be fixed
- if pedestrian cannot walk on carriageway and can on sidewalk
and it is separately mapped then use foot=use_sidepath instead

---

No idea:

- how to tag situation from (1) that distinguishes it from case (2)

Not sure:
- should we treat foot=no instead of foot=use_sidepath in case (2)
as invalid data

For start, is there a separately mapped sidewalk geometry there?
If no then tagging is invalid.
If yes, then I personally would be treating as invalid data and assume road to 
be 
pedestrian accessible, maybe flag is worth reviewing and ask users for feddback
what is going on there and ask for photo.

Does any router actually interpret access tags as you're describing?

It seems like quite a stretch that a router would automatically infer a
sidewalk's access tags from some parallel roadway,


Perhaps I should not have aimed for brevity.  I would not expect a 
router or any other data consumer to infer access tags from a parallel 
way.  In my theoretical sidewalk where walking is not allowed I would 
expect the separately mapped sidewalk way to also be tagged with 
foot=no.  In case it's not clear, I mean this as a joke and I don't 
expect this would actually be sensible tagging anywhere, but who knows.  
Essentially I'm just saying I don't think putting foot=no on the main 
roadway when sidewalks are mapped separately is helpful.  Just tag 
sidewalk=separate.


Joke's on me then! :-D

If foot=no is problematic for use cases like the one that Brian 
described, then foot=use_sidepath would be more precise for saying, "No 
feet *here*, but see also: separate sidewalk."

& then you have places like where I am, where e-scooters are allowed to use

Does any router actually interpret access tags as you're describing?

It seems like quite a stretch that a router would automatically infer a 
sidewalk's access tags from some parallel roadway, not least for the 
reason that we lack an established method to associate the sidewalk with 
the way. [1] (sidewalk=separate refers to a sidewalk way, but there's 
nothing in the other direction.) It would be something of a first for 
OSM that you could download a complete extract within a certain bbox, 
including any relation memberships, and the footways along the edges of 
this bbox could be subject to a tag that hasn't been downloaded yet.


Compounding matters, there are places where cyclists are prohibited from 
using sidewalks and other places where cyclists are required to use 
sidewalks when present. What should a router do if somehow it is able to 
determine the parallel roadway and finds a bicycle=no on it? What other 
access keys of the unconnected roadway are relevant to routing on a 
sidewalk? What about other things that are "part of the street", such as 
busways?

Right, this can be problematic, both for pedestrians (who might not know "the 
law" or "what pedestrian access am I actually allowed here?") as well as for 
OSM (how to tag?)

"Quacks like a duck" tests are good, though I think OSM can do better at 
specifying and realizing explicit tags — or implicit tags, because of 
well-understandable rules that a parser/router/renderer/use case can implement. 
 We seem to have a fair distance still to go here, as while Brian's question 
seems it is getting some answers (how you feeling about those, Brian?) it also 
seems like it's getting some "what about easements...?" side-discussion, as 
well.  There are likely other subtle issues here to be addressed, I think there 
are parts of the world where even what we've said so far won't completely 
describe the real-world fully or even sufficiently.

It's seldom easy around here!  But I'm delighted to be exchanging this 
roll-up-our-sleeves discussion as we do.

1. you're not allowed to walk on the carriageway (the way in question)
2. there is a sidewalk
3. the sidewalk is tagged separately
4. the sidewalk way does not have foot=no

So walking on this way is not allowed, but there is another way that you 
can walk on, and it's really close and should follow approximately the 
same geometry. It seems to me you can include this in your dataset.


As to the principle of sidewalk-like structures where walking is 
genuinely prohibited, I would say tagging that as a sidewalk would be 
incorrect. It looks like a duck, but it's probably something else.


There are instances that you wouldn't want to include in your router. 
E.g. https://www.openstreetmap.org/way/658000911, which is similar 
except there is no sidewalk=separate. Walking on this "sidewalk" is 
probably prohibited, because to get to it, you have to pass a sign that 
says no walking, except if you manage to cross a gated fence (at the 
southern end). The "sidewalk" is probably for some other use, possibly 
emergencies, possibly something else, possibly just a waste of space. 
I'm not a big fan of this particular tagging because it is misleading 
and confusing.


I don't know how you would tell the difference, apart from the lack of 
sidewalk=separate on the carriageway.

Re: [Tagging] Foot / sidewalk access tagging

[Zeke Farwell]

I'll try to answer the original question as succinctly as possible.  As I
understand it, the combination foot=no + sidewalk=separate means walking is
not allowed at all on this street and the sidewalk belonging to this street
is mapped as a separate way.  Since the sidewalk belongs to the street,
foot=no applies to it as well.  It must be a sidewalk where walking is not
allowed since walking is not allowed anywhere on this street.

Hmmm?

Possibly accurate but definitely confusing!

To me it says that there's a road here, which you can't walk on, but
there's also a separate sidewalk (is that even a thing? I thought
sidewalks, by definition, are hard up against the road?), but it doesn't
say whether or not you can walk on that? I guess I'd call it an error?

It would be much nicer to drop the sidewalk=separate from the road, & draw
a separate footway, which would fix everything!

Re: [Tagging] Foot / sidewalk access tagging

[stevea]

OSM is anarchy, a process, sometimes (mostly, I think) successful, though often 
messy.  It's not ringing up customer service and getting a Tier 3 professional 
answer, I'm sure you know that.  I don't need to say this, either, but 
"Patience!"  OSM is incremental.  (Sometimes, by millimeters or even microns!)

This is actually rather complicated, especially as "easements," a real thing in 
the real world, have hardly had their surface scratched in OSM.  It could get 
messy (I sigh, it's "usual") as in a whole Proposal et al, to tease apart how 
to map such easements, as they do appear to be extant in Texas (and other 
states).  I consider them a sort of "lazy legislation" where a pedestrian, for 
example, is expected to understand rather subtle aspects of law (property 
rights, trespass, etc.) and the legislature seems to have done the absolute 
minimum:  pass a law saying "can't walk in a roadway," pass a law making 
"mandatory but sometimes invisible" easements along roadways implicit, (so, the 
law says "they're there" but maybe you can't see them, even if you know them to 
legally exist), and dust your hands as "OK, we the ever-clever legislature are 
all done with this."  Leaves a bad taste in my mouth for both how I'm supposed 
to act as a pedestrian in such places (especially the ones with invisible 
easement — I might very well be on the wrong side of the road and could get 
ticketed on a really bad day) and for potential OSM tagging, which seems like 
it will need a "new headache" method of tagging (and mapping) these:  a big 
long strip of "easement" along every road where this is true?!  Ugh!  Say it 
ain't so!

Re: [Tagging] Foot / sidewalk access tagging

[stevea]

My understanding (in Texas, and other states) in this case (where there is no 
sidewalk and it is not legal to walk "in the roadway") is that in cases like 
these, there will always be an "easement" along at least one side of the road, 
where utilities (wired poles, perhaps underground piping...) are allowed, and 
so, too, is granted "permission of access" to pedestrians, for the right to 
walk along such easement.  This isn't quite-exactly "public property," as the 
easement remains a "strip" of private property along stitched-together private 
parcels, but by virtue of it being "an easement," explicit "public access" 
(e.g. pedestrians walking) IS allowed through such an easement.  So, for 
example, an access=yes tag (if not already implied) might be appropriate to 
explicitly include.

So, say you're in Texas, there is a roadway (and you are not allowed to walk in 
it, lest you run afoul of "pedestrian-in-roadway" ordinances) and there is NO 
sidewalk.  In this case there IS an "easement" (whether populated by utilities 
or not) where pedestrians are allowed, because pedestrians must be able to use 
the right-of-way of the road, too.  Just not IN the roadway, but along it.  
(And if there are wired poles along one side, choose that side).

Re: [Tagging] Foot / sidewalk access tagging

[Brian M. Sperlongano]

Hi,

The tagging that I cited was from Texas in the USA.  In that location, it
is illegal to walk in the roadway (where the cars go), but there was a
separate sidewalk where pedestrians are supposed to walk.  However, my
software works globally so I'm trying to understand how that
`sidewalk=separate` + `foot=no` combination should be interpreted on a
global basis, or if I should just ignore those combinations as a tagging
error.

So the situation is:
1. There is a sidewalk, and it's mapped separately
2. The road is tagged sidewalk=separate + foot=no
3. It's illegal to walk in the road itself because there is a sidewalk
(state law in that area)

 Sidewalk=separate means there needs to be such a way.
 However i would tag foot=use_sidepath, which means the same as foot=no
 but also indicates the existence of a separate way usable for routing.
 And only if the highway is a streets centerline, not a cycleway or
 other.

Re: [Tagging] Foot / sidewalk access tagging

[Ivo Reano]

I don't know in your area if all pedestrians who use the streets just
because they don't have a car are punished.
In Italy, only motorways and some major traffic routes are formally
"forbidden" to pedestrian transit.
If I found a foot=yes on a street, simply to indicate that one should not
walk in the middle of the street, I would delete that tag (and send a
message to the user asking what he meant).
It seems obvious to me that if I walk on a road I keep to the left (excuse
non-Anglo-Saxons, but this is the preferred direction for pedestrians on
driveways in the rest of the world).
While if I'm on a road with no traffic (not flat) I mostly walk on the
downhill side.
In short: if there isn't a sidewalk, and the street isn't reserved for
vehicles (but where do you live?) foot=no it seems absurd to me, or rather
wrong.

Ivo, Jrachi

 Hello,

 I am the author of a data consumer which generates a list of streets
 that are accessible to walkers and joggers. The idea is that a user would
 have a map of the streets in their town and can challenge themselves to
 walk/jog down every street, and they can look at statistics on which
 streets they've completed.  I use a 25-meter rule, so if a user can walk
 along the shoulder, or on a sidewalk/pavement, or in the verge, that's
 acceptable.

 I recently came across an unexpected tagging combination and I would
 like to understand how folks in various places would interpret this:

 highway=
 foot=no
 sidewalk=separate

 In my software's logic, I've made the assumption that foot=* applies to
 "the whole of the road" including the roadway, shoulders, verge, sidewalks,
 and so forth and thus excluded any roads that include that tag, regardless
 of other tagging. I came to understand that this tagging was used by a
 mapper to indicate that "pedestrians are not allowed on the roadway,
 however, they are allowed on the sidewalk"

 Would folks regard that as accurate data modeling?  I.e. should I
 change my software to treat streets tagged in this way as
 pedestrian-accessible, or would folks regard this combination as a tagging
 error?

Thanks Cyton.

Just to be clear, I'm only talking about automobile roads -
highway=trunk/primary/secondary/tertiary/unclassified/residential.
