Unfortunately, in rural areas, the state signage will flip flop between name and number. Also, if i remember correctly, there are a few areas on the eastern shore where the # stays the same and the name changes, but the signage references the road name.

I think it has come down to local knowledge and signing. This is the official wiki ruling on the matter, and the MD wiki doesn't have a special case posted: https://wiki.waze.com/wiki/Road_names/U ... rent_names

This is a tough one. My practice in nearly all cases has been to use the name as primary and the number as alternate. I've tended to limit exceptions to this to freeways and major highways that have few addresses on them (404 and 32 from 70 to 108, for example) or roads with truly obscure names. It is ultimately a local decision, but the name should be consistent and not flip-flop. I also hesitate to tell you to spend a lot of time on this because I don't know what Waze's plans are for using alternate names. If you are finding that a few intersections are the problem, then wayfinders might be helpful.

In the case of MD-26, I'd recommend using Liberty Rd as the primary name because there are many addresses along the route, Liberty Rd is a well known name, most signalized intersections appear to have both MD-26 and Liberty Rd posted, and most unsignalized intersections (except in Carroll County) appear to have Liberty Rd posted.
