I'm doing sidewalks in my area and unfortunately there isn't much convention to go off of. At a crossing where there are traffic lights but no specific pedestrian signals, should I be putting a Traffic Signals node on the pedestrian crossing? If so, at the corner, or where it intersects with the road?
In general, is there documentation somewhere for best practices for discrete sidewalks, and their associated curbs and crossings? I would like to get this right from the start, in a way that makes the data actually useful for people with visual or mobility impairments.
Thanks!
Whelp, this is the beginners-question chat! This is already quite advanced what you are doing there!
You will find more information on the wiki page on sidewalks and the crossings page. However, there is no consensus on how to do it. Some map it as discrete way (but this is a lot of work, duplicates some data such as streetnames), others map it as tag on the road. Both approaches have advantages and drawbacks; for some real-life situations it makes sense to do it one way and it others the other makes a lot of sense. And there is a grey area where neither approach is a good fit...
Not to mention that this is done differently in some countries due to OSM-tradition, different legal implications or forms of the sidewalk... So, good luck with this journey!
Believe it or not, I started last week. :)
My area has been doing sidewalks as separate ways, though very little is complete. I've already filled in more than a square kilometer of sidewalks with all their crossings and curbs, but just encountered my first intersection with this sort of weird grey area crossing where there is a traffic light but no pedestrian signal.
Well, that is impressive! Personally, I only map sidewalks separately if they are clearly separated by a decent amount (>1m) over a longer stretch of pavement
