Yesterday I took ~1 mln rides we made in December and matched them to
the OSM road network. With that I found a few hundred points where an
actual trace diverged from the matched one quite often. This usually
means a oneway tag is wrong, or a turn restriction is incomplete.
The result is this MapRoulette challenge:

Have fun,

Thanks, Ilya -- this *is* fun! You've caught a lot of bad tagging that's
been sitting for years. Looks like we're about a third of the way
through these already. Teamwork!
If you have the resources, I'd love to see this challenge repeated every
few months so we can continue hunting these bad tags to extinction, and
also keep up with new changes. A couple of suggestions, and I don't know
how realistic these are since this is my first time using Maproulette:
- From each task, before entering the edit mode, it would be great to
have a direct link to https://www.openstreetmap.org/directions with the
start and end locations encoded, so we can immediately check if the task
in question is still an issue. A fair number of them have already been
fixed, and/or I can't replicate. As of now my workflow is: Zoom in, turn
on data layer, click a building, click the
https://www.openstreetmap.org/way link in the popup, pan around the map
to find approximate start and end points, and get directions via OSRM.
It would be great to save some steps and to get the exact same start end
end points you used.
- When invoking iD, the changeset comment field is auto-populated with
#maproulette -- is it possible to also auto-populate with the challenge
and task number?
Thanks for your work, Jason
