Pre task: Split the tasks in case they are too big

JOSM Workflow

Setup

  • Task Config
  • Activate the following in from JOSM preferences > Map Settings
  • Map Paint Styles: Lanes and road attributes
  • Tagging Presets: lane attributes
  • Filter out non road features with boundary: | leisure: | landuse: | waterway: | amenity: | natural: | building:
  • Use inverse filter: highway=motorway | motorway_link | trunk| trunk_link | primary | secondary | tertiary
  • Read http://wiki.openstreetmap.org/wiki/Key:turn:lanes

Mapping

  • Map turn lanes from tertiary and up.
  • Check every intersection for tun lanes indicated by white arrows
  • Split the road into segments based on the total number of lanes for the segment
  • For each road segment tag the turn lanes based on the road markings in the direction of the way. Eg. turn:lanes=left|through|right. See OSM turn:lanes
  • For bi-directional segments, use turn:lanes:backward= and turn:lanes:forward= to specify turn lanes in each direction.
  • Verify correct tagging using the Lane attributes style
  • Leave a comment on the blocks which does not have any turn lanes
