My understanding of the thinking behind the African wiki was that it is not possible to say what the importance of a highway from the width of the highway in Africa so from an image we don't stand much chance of being too precise.
I think the most we can hope for is to map the highways and expect the locals some time to reclassify them. In general when validating I may up an unclassified to a tertiary if it connects many settlements and other highways and I may up a path to an unclassified if it looks wide enough but otherwise I feel I'm out of my area of expertise which is probably identifying zebar crossings on paths in the middle of nowhere and deleting the tag. Does that help?
