There may be no "most common route designator". A semi-local example: If I am
directing you east over Sonora Pass I'll tell you to go east on CA 108. If I
direct you to Yosemite I'll tell you to go east on CA 120. But for a number of
miles they are the same road with dual signage with no obvious method of tell
which one is the most common designator.
(You can probably tell what the road officially is by looking at the very
cryptic and hard to read version of a mile/information posts that CalTrans uses
but most motorists never notice them and if they do they are very difficult to
read or decipher without stopping.)
Some of your examples are in areas I am not familiar with. But in both the San
Francisco Bay Area and Los Angeles there are named freeways. I notice that in
the Bay Area the name is almost never used whereas in LA it seems both are used
with the name being more common. In either case I'd expect the name key to
specify the name and the ref to specify the route number. How you decide that a
local would be more likely to use the name (LA) or the ref (SF) I haven't the
fainted idea.
