[OSM-talk] Guides to improve navigation data in OpenStreetMap

[Paul Johnson]

This is the more logical interpretation; the key:lanes page should be
updated.  cycleway=lane is great, but where is the lane?  What about
multiple lanes? This does happen, and they're not always next to each
other, and any location there's multiple bike lanes or bicycle turn lanes
can't be completely properly mapped without this.  This is a nagging issue
for anyplace with complex bicycle infrastructure.
