Thank you for the response and for explaining the method you used for these changes. As you pointed out, the trunk definition on the East Africa Tagging Guidelines page does differ from the Highway Tag Africa definition. Since several of the countries you’ve made these changes in follow those guidelines (Rwanda, Uganda, Burundi), how would you feel about updating the trunk network to reflect that?

Regarding the trunk highways in countries that follow the Highway Tag Africa definition, I agree that they do not need to be paved nor divided to qualify as a trunk. However, I do think that solely basing the importance of a highway from its ref can lead to inconsistent classification. Using a couple of highways in Congo as examples, RN6 (https://www.openstreetmap.org/way/322555033 to https://www.openstreetmap.org/way/322115447, a route that is mostly just wide enough for 2 vehicles to pass, unpaved, and only connects a few small villages) and RN1 (https://www.openstreetmap.org/way/243087995 to https://www.openstreetmap.org/way/517768410, a route that is multi-lane, paved, and connects the major cities of Congo) have different levels of importance within the greater Congo highway network. This difference necessitates different classifications even though they both carry a national highway ref.

There are also many highways that I would consider simply too insignificant in both importance and infrastructure to be considered a trunk. For example, RN9 in Democratic Republic of the Congo (https://www.openstreetmap.org/way/33671087 to https://www.openstreetmap.org/way/469248644).

Something else that I would like to point out is that some African countries have their own highway classification schemes to take into consideration. For example, the WikiProject Central African Republic page (https://wiki.openstreetmap.org/wiki/WikiProject_Central_African_Republic#Road_network) notes that the most important highways in the country, those that connect the capital cities, should be tagged as primary. The OSM Africa Telegram (https://t.me/OSMAfrica) may have additional thoughts on if the RN, NR, and N refs should be classified as trunk, if you would like to open this discussion to a broader audience.

Thank you again for your response; I’m looking forward to hearing more of your thoughts on this!
