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

[Marc Gemis]

Please read http://wiki.openstreetmap.org/wiki/Lanes, which describes
the ":lanes"- subkey. This page states:

"Please be aware that this extension covers all kinds of lanes for all
kind of vehicles and is not restricted to motorized traffic."

this means that all turn:lanes, change:lanes, access:lanes,
forward:lanes, backward:lanes, etc. should count ALL lanes. Only the
lanes-tag on its own count the lanes for motorized traffic.
BTW, this is often neglected by QA tools that try to compare the sum
of forward and backward lanes with the number in the lanes tag.
