In Ethiopia most of the population lives in rural areas outside of towns and villages. The existing OSM road tagging is inadequate to adequately document the functional use of a road.
The Africa Highway tags are a good start but do not have a tag that is appropriate for rural residential roads.
At the State of the Map Africa 2017 http://sotmafrica.org/ we will be discussing the tagging for roads in an Africa context. #SOTMAfrica
