Objective: The goal is to improve the road attributes related to lane guidance. We'll be reviewing and mapping missing lanes and turn lanes information in major intersections (motorways, trunk, primary, secondary and tertiary).
Regions we are reviewing/mapping:
Starting with the following city [cities]:

Workflow: We'll be following OSM (https://wiki.openstreetmap.org/wiki/Key:turn, https://wiki.openstreetmap.org/wiki/Lanes global and local policies, along with any other guidelines as appropriate.
Apart from the tags that refer to turn lanes and lane count information, in some specific situations, we will also use:
**change:lanes=*** on the OSM way, to indicate that there is a lane change restriction, as described here: https://wiki.openstreetmap.org/wiki/Key:change
lane_markings=no on the OSM way, for existing information, where there are no markings that separate the individual lanes of the road (https://wiki.openstreetmap.org/wiki/Key:lane_markings)
We will update the list if needed.
Validation: We'll be following the validation guidelines mentioned in our wiki: https://wiki.openstreetmap.org/wiki/Grab#Quality_Process
