Alternative Junction Naming Scheme for UK

[Dave2084]

I've now added the basic framework to the wiki, please have look and let me know what else needs adding.

I'd like to have added photos of signage for a fully worked example but I'll have to take the pictures myself as "borrowing" them from streetview is probably not a good idea for the wiki.

[Dave2084]

Fine with me. Just a parochial point re the M25 - is it possible to show an example of an M25 junction where the ramp is labelled M25 (N) (or whatever) despite the carriageway being M25 (ACW)? I think we agreed this in a discussion so that the nav follows the signage.

Feel free to dive in and add a specific example that you know is good.

Or if you prefer, post it here and I'll add it.

Something like M4 (W) J4B to M25 (N) - does it need to be spelt out that the ramp differs from the carriageway?

I guess it depends on how you map the junction.

As this junction is a shared slip road for M25 CW & ACW I'd expect is to be "M4 (W) J4B to M25" and where this splits to go to the relevant direction it would change to "Entry to M25 (N) J15" or "Entry to M25 (S) J15"

That's how I'd do it anyway.

I've amended the wiki to reflect this and also added some clarification text.

I'm also wondering if the case for not adding direction to an onward road (where we have no choice) is valid. I expect there motorway interchanges with dedicated lanes for different onward directions (though I can't think of an example).

Feel free to discuss these special case major junctions!

I've now found an example:

M25 (CW) at junction 16 heading north has separate ramps for M40 east and west.

It would be Important to have the direction here to ensure the user takes the correct slip (to match signage) as they are only about 1/2 mile apart.

I'm going to remove that note excluding direction for onward roads from the wiki.

[Dave2084]

Manchester or Hull? Hard choice

Are they abbreviated to (M) and (H)?

Is this ok for M4/M25?

Looks good to me.

I'll own up now though; My OCD made me realign the exit ramp of the M4 (W)

Rather than staring with solutions, could you run through what you consider bad about the current scheme, and why, for ramp naming and junction naming?

Personally, I find the current naming of ramps to be ugly and confusing, but I guess this could just be me. When I'm driving along a motorway and see that the next ramp is named "M8 (E) J15 Exit", the only useful bit of information is "J15", and the rest of it is redundant [for navigation]. The junction numbers on motorway signs are typically tiny compared to the rest of the information (unlike in the US). Therefore, seeing which secondary road the junction is for would be helpful.

Perhaps neither scheme is perfect, but I think mine is better

I'm definitely with Tim on this one. I think the current format is very confusing. Do we have any way of measuring how important navigation on ramps is versus traffic reports? Any data we could use? If not, maybe a survey/vote? Other than city name, is there no other way of having different information for reports vs navigation?

[dknight212]

Not sure if it affects anywhere else but I try to use M25 (N) etc on the ramps since that matches the signage, whereas the motorway itself is labelled M25 (ACW) or M25 (CW) as appropriate. Any problems foreseen with this?

[dknight212]

I wonder how TTS deals with (CW) and (ACW)?

I'd rather not have to spell it out in full!

[dknight212]

If you're going to have Waze parse the road name, why not just use a pipe character to separate out the navigation from report text eg J15:M4|M25 J15 exit?
