When using ImproveOSM, the Telenav tool to find and add missing roads (and other missing things) in OSM, sometimes there is just no detailed aerial imagery to see exactly what road type it is.
While you could say, 'Well without being able to see, I won't add anything'. But because ImproveOSM uses actual GPS traces from drivers, you know that people have been driving there. From the image in the example you can see that a fair number of people must have taken this route, so there must be some sort of road there.
So what I suggest is to add the road as simply
highway=road (generic road tag). Then you or someone else can improve it later, based on better imagery or local knowledge.
The example in the image is this new way.
Remember that you can select multiple tiles on ImproveOSM by holding
Shift while selecting. That way you can more quickly mark multiple tiles as Solved.
