well be the ONLY way to get from A to B by foot. I was under the impression 
that 
in the US in many cases there are even fewer footpath routes going the same way 
as the roads?

'Safe' for pedestrians to use is simply undefinable as we have already decided 
when trying to identify URBAN areas where one would not walk on one's own! MAPS 
can't define what is safe. But they should at least show alternatives where 
they 
are available?

I disagree that this is an undefinable problem, as I pointed out
before you only need to come up with a base line, could an average
human adult walk down this way without getting hit by a car?

Would an average human adult walk through some seedy part of town
without getting mugged?

If you wanted something more definite, police injury records could
provide alternative verifiability, if as John pointed out 5 people
were hurt or killed trying to cross a road than it's obviously not
safe.

2010/6/2 John F. Eldredge j...@jfeldredge.com:
 With many high-speed highways (such as Interstate Highways in the USA, 
 Autobahn in Germany, etc.) you may have wide shoulders, but pedestrian use on 
 the shoulders is inadvisable and/or illegal, because crossing to the other 
 side means having to judge the speed of multiple lanes of traffic.


don't know for US Interstates, but for all the German Autobahns it is
legally forbidden to use it by foot, horse, bicycle, tractors, any
other motorized vehicle that has 50ccm and less and any other vehicle
that has a maxspeed equal or below 60 (or 80km/h, don't remember
clearly).

The same applies to Kraftfahrstraßen, which are roads signed with
http://de.wikipedia.org/w/index.php?title=Datei:Zeichen_331.svgfiletimestamp=20060729145019

This one (which can besides trunks also be primaries or maybe
secondary roads) we tag additionally with motorroad=yes.

These are legal restrictions and I don't expect routers to lead you
there on foot. On all other roads (no matter if inside or outside
closed settlements, and given that there are no other explicit
restrictions) you are legally entitled to walk, ride your bike/horse,
... even though you usually wouldn't (have to) do so on bigger
streets.

 Room to get off the road.  That's what I was referring to as a shoulder.

Here in the third world (Derbyshire, England) we call those hedges.  
If I avoided walking along roads without a shoulder or sidewalk of any

I think that we're hitting cultural differences here.  When I've been in 
the US there seems to be more of a general assumption that 
non-residential roads are for cars only and other paths (if provided, if 
you're very lucky) are for cyclists and the tiny number of pedestrians.  
In the UK the assumption has historically been that most roads are for 
everyone, with cars if necessary giving way to horses and pedestrian 
traffic.  Obviously some roads (e.g. motorways, some trunk links) are 
signed exceptions. 

It simply isn't possible to globally say that a road without a sidewalk 
is safe or unsafe (as opposed to legal) based on its attributes, unless 
someone's been there and said yes, I've been down there and it's safe 
to walk down - even then it'll vary by time of day / year.  Does anyone 
already use tags to indicate that?  How widely are they in use?  I can 
see lots of suggestions further down the thread but am more interested 
in what people are already using.

One advantage that OSM has over the commercial people is that routes get 
mapped proportionately to how real people actually want to use them 
rather than what's commercial available or commercially viable to 
re-map.  If you try and use Google Maps for pedestrian routing in 
England it'll avoid major roads, but it also ignores the plethora of 
footpaths (and more recently cycleways) that are available*.  I don't 
know of anyone else (and in the UK outside of towns that includes the 
Ordnance Survey) who has up-to-date non-road pedestrian paths available.

Other than in exceptional circumstances (e.g. Postman Pat) I doubt that 
there's any money in pedestrian routing.

Cheers,
Andy


* Google's public transport (essentially bus) routing is excellent 
where it's available though - although it does seem to assume that you'd 
rather wait an hour for another bus rather than walk a couple of miles 
though!

Then don't use tags which indicate the legal status.  Easy peasy, right?

The rest of your post focused on what a routing engine should do.  But
this discussion isn't about the routing engine.  Different routing engines
are going to have different rules.  This is about the data, and the data
should be unambiguous.  That means not using the same tag for illegal and
bad for the environment and unsafe.

Hmm, is shoulder a fairly universal term?  Because shoulder=no would be
much more daunting to me than pavement=no.

Also, if the street really is dangerous/suicidal, is there any chance you
can report it to the govt. so they can either fix it or ban pedestrians?

Ideally, yes. But routing software can't possibly process the logic
correctly in cases like these. Some roads may not have a pavement, but
they are safe for pedestrians due to the lack of traffic. In other
cases extreme footways should not be used because of crime.

If you don't trust your own opinion, ask a few locals if they would
advise a tourist to walk there. If they say no, then tag them with
foot=no and add a note describing why you did it.

 I don't think this would be correct: foot=no usually means you are
 not legally allowed to walk here, not this road may be dangerous for
 you to walk on

 using a different tag may be appropriate, however

Which one, or do I have to invent a new one ? The problem is that
tagging standards change faster than the map can be reviewed. For
example, I did most of my mapping during 2008. At stage the access=no
tag indicated that Access by this transport mode not permitted or
unsuitable. dangerous is one form of being unsuitable.

I'd much rather use the tag that is the best approximation of reality
and add a note if it is really necessary.

What does lack of traffic matter?  Unless you mean absolutely no traffic, I
don't think that makes much difference.  If the road is unsafe to walk on,
I'm not going to walk down it whether there's 1 car a day or 10,000.  If
there's a low enough speed limit maybe.

If you don't trust your own opinion, ask a few locals if they would
 advise a tourist to walk there. If they say no, then tag them with
 foot=no and add a note describing why you did it.


So because a few locals wouldn't advise a tourist to walk there you're going
to tag the road equivalently to one that is illegal to walk on?  I think
we've gotta do better than that.  I'd prefer the ambiguous foot=dangerous to
foot=no.  Especially if you're saying that high traffic + no pavement =
dangerous (I've walked on plenty of roads with high traffic and no pavement
- as long as they have a shoulder I wouldn't tag them as foot=no, never,
way too dangerous, I'd tag them as foot=try to find a better route, but if
you must, use caution.

How about foot=destination? :)  I'm kidding, but it'd be better (and more
accurate) than foot=no.

By that logic you should never leave your house. What if a storm
suddenly appears and you get hit by lightning ?

As traffic volumes increase, following distances decrease and drivers
become overloaded with all the information. Their view may also be
obscured by the traffic. And if the oncoming lane is also full of
traffic, it gives less space for drives to take evasive action.

I've had a number of close calls where I was cycling and a driver
overtook the traffic on the outside at high speed i.e. on the left in
a country with left hand traffic. But I guess that's largely a
developing country problem.

 How about foot=destination? :)  I'm kidding, but it'd be better (and more
 accurate) than foot=no.

I won't argue with that.

Not that I am native, but I think that shoulder is a different term
than sidewalk/pavement, because it can also be unpaved, while a
pavement IMHO should be paved. A shoulder is simply the side of the
road (I guess), kept free from traffic, while a pavement is designed
for pedestrians.

Perhaps bikeshedding here, but if you were to ask me to walk on the
pavement I'd look at you strangely. To me (and to many Americans)
pavement implies the road surface itself, not the path along the side
of the road.

  You seem to have missed the rest of my post.  I was arguing that a road

  shoulder, and traffic traveling at 55 mph, and only 1 car a day, I'm not
  walking down it.

 My mother often goes for walks on roads that have 3 or 4 times that
 amount of traffic at that speed, and she isn't the only one. It's
 perfectly safe to do so because there is room to get off the road and
 you can usually hear them coming, especially when it's a B-Double*
 instead of a car, I've never heard of any pedestrians being clipped or
 killed.


Room to get off the road.  That's what I was referring to as a shoulder.

The amount of traffic nor the speed they travel at nor type of traffic
 doesn't inherently make walking on a road unsafe.


Agreed.  100%.


 I have no idea of the legality of walking along roads outside towns,
 but hitchhikers do it often and I don't think they get arrested.


Here's the (relevant) law in Florida: Where sidewalks are not provided, any
pedestrian walking along and upon a highway shall, when practicable, walk
only on the shoulder on the left side of the roadway in relation to the
pedestrian's direction of travel, facing traffic which may approach from the
opposite direction. 

So, technically, here in Florida, walking on the roadway when there is a
shoulder available (and practicable) would be illegal.  Interestingly,
shoulder does not seem to be defined in the law, but I've always assumed
it meant the part of the right of way (paved or unpaved) which was able to
be walked upon and which was not part of the roadway.

However I think it would be a great idea to indicate the difference
 between legally disallowed and just not a good idea due to personal
 safety, I don't think re-using the foot tag is a good idea, because it
 might be legal, but not safe to do late at night because you'll get
 mugged etc etc etc.


Best case scenario, if we really want to be able to produce adequate walking
directions for people unfamiliar with the route, would be to map the entire
right of way as one or more areas with surface=* designations.  Anything
short of that is probably going to be insufficient, because there is so much
variation as to what people would consider safe enough (between different
people, and even between different times and scenarios - if I'm taking my
kids with me I might want a 30 ft. wide shoulder but if I'm walking alone a
much smaller one would be acceptable).

The shoulder of the roadway is usually provided for a couple of
reasons, firstly it can help prevent the edge of the road way breaking
up when large or very large trucks need to pull over a bit to pass
oncoming traffic, it also allows a car to get off the road if they
break down, I don't think they were intended for pedestrians :)

If you want 10m/30' wide shoulder some kind of width tag would be more
appropriate than indicating a dangerous path or not.

At the very basic level all we can assume is an older teenager or
adult is using the map data in some fashion, for other groups we would
need additional tags to indicate additional things, but if it isn't
safe for an average adult it won't be safe for any other groups
either.

She wasn't playing, she was walking to her destination.  I can't tell from
the pictures whether it was her fault for following the route, her fault for
walking on the wrong side of the road, her fault for not staying close
enough to the side of the road, the government's fault for not banning
pedestrians, the government's fault for setting too high of a speed limit,
or the car driver's fault.  From the aerials it does look as though there
was enough room on at least one side of the road to walk (it wasn't a paved

Ridiculous that she'd try to blame Google, though.

Looking more closely, there is a sidewalk, which turns into a cycleway (
http://www.openstreetmap.org/browse/way/40967519), about 50 feet from the
roadway, on the southbound side which is the same side she was walking on.
And if she had been using the sidewalk while heading north on Main St, it

Here's a case from NZ where something similar happened that didn't lead to
injury. Until this article was posted, Google Maps directed people through
Wellington's bus tunnel, a 1 way tunnel which barely has enough width for
buses to travel through.

http://www.stuff.co.nz/national/3552037/Google-maps-off-course-with-walk-through-bus-tunnel

At that incident Goolge's response was:

Google spokeswoman Annie Baxter said the walking directions search function
in Google Maps was still at an experimental phase.

We clearly advise people to use caution as routes might be missing
footpaths or pedestrian-friendly paths.

This implies that they they're undertaking a responsibility to notify people
when routes are generated. I guess if the BlackBerry version doesn't include
the disclaimer, there's an argument to say that Google didn't meet its
(self-imposed?) duty of care to the consumers.

Still, even if they breached the duty of care, the injured woman will still
need to establish that the breach was a cause of her injury.
