I think the POINT here is that UNLESS there is a legal restriction on walking down a road, then CAR DRIVERS should be aware of the fact that there may be other people using the road? In the case being discussed, it is not clear if the woman was following the correct procedures when walking on RURAL roads ... wearing something highly visible ... walking facing on-coming traffic.

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. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Anthony wrote: 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 sort I wouldn't get very far. 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.

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.

1... What's the correct way of tagging a street as 'dangerous/suicidal' for pedestrians in OSM?

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.

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. -- Jeff Ollie ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Jeffrey, when the thread was started the cycleway was incorrectly tagged, but I fixed it soon afterwards. Cloudmade will catch up soon enough.

I was arguing that a road with no pavement but with a shoulder is *not* unsafe. OTOH, if the road has no 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). ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

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. 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 :) 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.

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. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Did Google add their notice after the fact? *Walking directions are in beta.* Use caution – This route may be missing sidewalks or pedestrian paths. 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.
