Examples:
1. Here's a restricted junction that only goes to (and from) the A659, so ramps can be unnamed. Users won't even get an instruction to enter the A64.
2. Another restricted junction. Exit ramp could have been unnamed, but needs to be named "A162" so that there's a 'keep right' for people turning to go north. Entry ramp is named "A64" for shorter instructions, but it doesn't really matter either way.
3. Simple junction with roundabout. Exit ramps are simple "A1237", even if driver is actually headed to a different road. Entry ramps are named "A64 > city" to provide disambiguation.
4. A typical roundabout junction. Exit ramps have two A roads on them as listed on the signs, even though there's also a B road (not signed).
5. A numbered junction from A1 (M).
From the north, exit ramp is simply "J44 to A64" as before, and entry ramp is unnamed.
From the south, exit ramp is also "J44 to A64", followed by a 'Keep left to A64 towards Leeds". There's no instruction for "A64 > York", so it could be unnamed.
The roundabout has two exits that are named "A64 > city". Not strictly ramps, but this shows how we can improve the navigation instructions in other situations too. This may get out of hand though.
6. This motorway split will announce: "Exit left onto Junction 41 to M62" and then either "Keep left onto M62 towards Hull" or "Keep right onto M62 towards Manchester".
Had the exit from A1 been unnamed, then we'd have "Exit left onto Junction 41 to M62 towards Manchester" followed by "Keep right onto Junction 41 to M62 towards Manchester", which I think is unnecessarily wordy (like you get here).
