There are only 32 uses according to Taginfo and the tag isn't mentioned in
the wiki. However, there are 4,450 uses of bicycle:lanes and that tag is
briefly mentioned in the wiki. [1][2]

I'm unsure if foot:lanes works as a alternative to pedestrian_lane or if
this is only an addition for more complex situations. In any case i don't
see a problem with it as opposed to sidewalk:right:kerb=no.

Besides, i just realised that sidewalk:right:kerb=no could also mean a
parallel footpath without kerb but with another physical barrier, like for
example here [3].

Thanks for the tagging example! ^__^
 have never tagged lanes before. 

Is "foot:lanes" An established value? 
Or is that what we are discussing?

if there are nuances, I would see them between this shared lane for pedestrians 
and motorvehicles and no footway marking at all (sidewalk=no), not between a 
sidewalk and the shared lane.

It isn't a nuance of one English dictionary. I've checked definitions
of a sidewalk in a few other languages (German, French, Spanish,
Italian, Serbo-Croatian, Swedish, Chinese and Japanese) – they mention
either that a sidewalk is raised [1][2][3][4][5], usually raised [6],
usually about 10 cm raised [7] or structurally divided from the
roadway [8].

Besides, the US Federal Highway Administration (FHWA) differentiates
between sidewalks, pedestrian lanes and shoulders [9]:

"Sidewalks are physically separated from the roadway by a curb or
unpaved buffer space." [9, p. 82]

"Pedestrian lanes provide interim or temporary pedestrian
accommodation on roadways lacking sidewalks. They are not intended to
be an alternative to sidewalks and often will fill short gaps between
other higher quality facilities." [9, p. 102].

Representing the lane as a lane is quite simple using the established 
lane tagging scheme, e.g. on a oneway road with two vehicle lanes and a 
pedestrian lane to the right:


lanes = 2  (counts only wide lanes for motor_vehicles)
access:lanes = ||no  (prohibit access to the third lane)
foot:lanes = ||designated (allowing foot access to this lane)
width:lanes = 3|3|1.5
colour:lanes = gray|gray|green  (if you like colours...)

These tags can be used to reconstruct the lane structure of the road 
without doubt, but we still have to find a routing engine that is able 
to cope with that...

Not much, but luckily most kerbs (at least those i came across) are
much higher (usually 10 cm and more). They are only lowered at
pedestrian crossings or at driveways. Cars and buses sometimes
accidentally touch kerbs while driving (on narrow roads) and then get
thrown in the other direction. So i'd say that they definitely provide
some safety to pedestrians.


That might be the case for the place where you live. Here is a randomly 
picked street from Frankfurt with what I would call the typical German 
kerb in residential streets:

https://www.mapillary.com/map/im/MB7QKRH0wkXrCicGrK9HpA
(and no, parking on the kerb is not allowed here even though almost all 
cars do it in this street)


They might be a bit higher and more rectangular on major roads, but more 
than 10 cm height is really rare.
Also note that most of the height of the kerb is only because the water 
drain is lower than the road surface.

For pedestrian safety this seems to be a serious compromise, likely not a
situation where parents would like their children walking to school if
avoidable.
I'm not sure I would want these lanes to integrate seamlessly and
automatically with existing pedestrian routing.

Me too. As I see it, the core of the question comes down to whether the
OSM data model should put a pedestrian road section without a kerb in
the same general category as one with a kerb, or whether these should be
treated as separate concepts.

To me, it makes more sense to consider them as roughly the same thing
and model the distinction with an additional tag. For most use cases,
data users can likely handle them very similarly, even though I
acknowledge that there may be exceptions (such as Markus's example of
navigation for blind users).

Yes.  It's as idiotic as us Brits calling underpants "pants"  because the
sidewalk is paved
but the road is also paved so both are pavements.  But that's what we do.

However, in some dialects it is also known as a causeway.  Probably

I would be careful with adding a generic access=no to shoulders, because
special types of vehicles or in certain conditions often are allowed to go
on the shoulder (e.g. bicycles).
The foot=designated tag as a lane tag makes sense (differentiation between
shoulders with general access for pedestrians vs. shoulders dedicated to
pedestrians. For the swiss example, vehicles are allowed to drive on the
lane anyway (which makes it less a "shoulder" I guess).

I agree with you that this is is a sidewalk. 

I spoke too quickly when I said that all sidewalks have kerbs. There is clear 
delineation that there is a separate, yet adjacent way for people, even though 
there is no kerb. Sidewalks always have some kind of physical barrier (a raised 
kerb or a kerb barrier), a materials change, or **some physical 
representation** that it is "not part of the road".

Lanes always imply that you are "part of the road". That you are "in the road". 
A cycle path and a cycle lane are very distinct, in all their forms, and this 
is the difference. 

We can all imagine a bus lane, a turn lane, a cycle lane, and whatever a 
"pedestrian lane" might be in the road. It's part of the road. It's marked with 
a (painted) line to separate one from the other. The lane feels like part of 
the road. The green lanes I deal with in Japan are clearly part of the road. I 
don't know how to map them as a lane, but it is clearly a lane, and not a 
sidewalk. 

Good luck with working this out.

Shoulders are a common feature on many roads. And the tagging for this is 
already established. Maybe a different way to tag kerb-less sidewalks thus 
would then be 

shoulder=right
shoulder:right:access=foot
(or access no and ...:foot=designated?)
shoulder:right:width=1

Though, in regards of software support,  I  my earlier suggestion is better, as 
no modification on existing software is necessary to understand that a sidewalk 
without kerb is still for pedestrians and used the same as a sidewalk, 
regardless of whether in (Oxford) English, one may or may not call this thing 
"sidewalk".

 (Existing) software will treat shoulders primarily as a feature relevant for

“Sidewalk” is North American English, but it’s used because the
British term is “pavement”, which is confusing due to its dual
meaning. As a North American I would expect it to be separated from
the road by a curb (kerb) or a strip of grass.

Oxford dictionaries definition, Pavement:
"1. British A raised paved or asphalted path for pedestrians at the
side of a road.
- ‘he fell and hit his head on the pavement’
- North American term:   sidewalk"
https://www.lexico.com/en/definition/pavement

Wikipedia claims:
"... normally separated from the vehicular section by a curb. There
may also be a median strip or road verge (a strip of vegetation..."
https://en.wikipedia.org/wiki/Sidewalk

These definitions fit my impression, as an American, that a "sidewalk"
is a separate feature, not part of the same paved road surface as the
main lanes of the highway.

If there's just a painted line, we would normally call the space
between the line and the edge of the asphalt "the shoulder" of the
road in a rural area, or it can also be a "bike lane" if it's wide
enough and there are certain markings.

So I'm in favor of a new key like pedestrian_lane=right/left/both,
rather than calling these a type of sidewalk

This is the most important information. 

it should be tagged as a “footway lane” or “pedestrian lane” or similar.

a "sidewalk lane” implies a regular kerb separated sidewalk. ___

2019-10-20 Thread Volker Schmidt
I think in bicycle-OSM we have kind of an tacitly agreed approach: bicycle
lanes (divided from motorised traffic by a painted line) are generally
mapped on the road way whereas separate parallel cycleways are tagged
either on the road way or as separate way, with the former often being the
first, fast mapping and the latter being considered the more advanced
mapping.

I don't know how it is elsewhere, but in Switzerland vehicles are
allowed to drive on the pedestrian lane as long as pedestrians aren't

Not much, but luckily most kerbs (at least those i came across) are
much higher (usually 10 cm and more). They are only lowered at
pedestrian crossings or at driveways. Cars and buses sometimes
accidentally touch kerbs while driving (on narrow roads) and then get

"yes" isn't the only value of sidewalk=*, there's also "right",
"left", "both", "no" (plus "none") and "separate". [1] This isn't
compatible with sidewalk=lane.

Why not inventing something different for a different feature? :)

[1]: As well as some less useful values like "this" (156 uses!?),
"bad", "both;right", "right;none", "10" or "forest". :D

I dislike using these tags for pedestrian lanes for the following
reasons (sorry if i repeat myself):

  * It doesn't make sense: if it doesn't have a kerb (or any other
physical barrier) it isn't a sidewalk.

  * Blind people are able to make out a sidewalk, but not a pedestrian lane.

  * It's misleading: Data users may not know the tag
sidewalk:right:kerb=no and thus may make wrong assumptions. For
example, a navigation application may guide a pedestrian along a route
with only pedestrian lanes instead of safer route with sidewalks.

  * pedestrian_lane= is simpler for mappers and data users.

  * The distinction between physical separation or road markings is
already made for cycleways.

As sidewalk:right:kerb=no sidewalk:left:kerb=no has only been used 4
and 9 times respectively, almost no retagging were required.

> The most important thing is to tag whether there is a sidewalk or not. 
> Regardless of whether it has a keen [kerb] or not.

I disagree: as already written, a sidewalk offers some safety for
pedestrians because of the kerb, while a pedestrian lane doesn't.

We have a widely used scheme for tagging cycle lanes/paths on the road way:

Extrapolating from that for the pedestrian "lane" seems obvious to me:
sidewalk=lane (plus variants).
For separate sidewalks there is
sidewalk=yes (plus variants)

How about:

Regardless of whether it has a keen or not.

According to taginfo, sidewalk:right:kerb is already used a few times:

Mapping a lane as a separate way isn't ideal, because this separates
the lane from the rest of the roadway, leading to routing problems:

I agree with you, and I tag all separated standard sidewalks as “sidewalks” (iD 
preset).

however, there are a lot of narrow roads in Japan where the side of the road 
(between the white lane border line and the barrier wall along the road) is 
painted with a (thin) green stripe, and is considered a pedestrian path - 
usually around schools where children walk. The infrastructure in the area is 
very old, and they cannot widen the roads to be safer, so they paint the green 
line on to remind drivers to be safe and keep the pedestrians on one side. this 
is only around schools with narrow roads. New roads all have separated 
sidewalks, so no painted area is necessary. 

I tag the green line as a highway=path and add a note=* to the way. 

One example I have seen is much larger, and is a new “lane” created by 
converting a 2-way road to 1-way and giving the margin to pedestrians. 
https://www.openstreetmap.org/way/667338935 
.

I do not think this is ideal, but it does properly map the marking and the 
routing that should be used for pedestrians. usually many roads in the area are 
narrow, and the designated way is best. 

If some method is standardized, I will correct my mapping. 

Note: these are not the blue cycle-lanes or cycle arrows in the road found on 
many narrow high traffic roads.

[Tagging] How to tag pedestrian lanes?

2019-10-19 Thread Markus
Hello everyone

I have a disagreement with another mapper (changeset comments in
German [1]) regarding the mapping of pedestrian lanes, i.e. lanes on a
roadway reserved for pedestrians (example [2]), and would like to hear
more opinions.

[1]: https://www.openstreetmap.org/changeset/75900746
[2]: https://commons.wikimedia.org/wiki/File:Pedestrian_lane.jpg

The other mapper thinks that pedestrian lanes should be tagged like
sidewalks (pavements), because sidewalk=* or footway=sidewalk just
means a footpath along a road, and that the absence of a kerb can be
tagged [sidewalk::]kerb=no.

However i think that a sidewalk requires a physical separation to the
roadway (usually a kerb). While a sidewalk provides some safety for
pedestrians, a pedestrian lanes does not. In order that data consumers
know that it may be less safe for pedestrians to use a road with a
pedestrian lane compared to a road with a sidewalk, i think it is
important to tag pedestrian lanes differently. (The tag i used was
pedestrian_lane=). Besides, the distinction between
physical separation or road markings is already made for cycleways: if
there is a physical separation we tag it cycleway=track, if there are
only road markings cycleway=lane. So it only seems logical to also
make the same distinction for sidewalks and pedestrian lanes.

Thank you in advance for your replies.

Best regards and have a nice Sunday,

Markus
