So we should get rid of the numbers? I know I'm being a bit extreme, but if they don't serve a purpose, why did we start using them. Just because there are ways to manage without them, doesn't mean they don't have utility. When I was growing up, my dad taught me to navigate with a road atlas, and using road numbers and junction numbers, made the whole thing quicker and easier. As I said, less of an issue now, with the ubiquity of SatNavs, but there are cases they would still have utility, listening to traffic reports on the radio, maybe navigating in a country where the names on the signs are in a language you can't pronounce.Herned wrote: ↑Fri Jun 07, 2019 19:12Head to Cambridge, then follow the signs for the Midlands until you get to the M6. Possibly including "bear in mind to turn off at Huntingdon". And that's itrasingram2 wrote: ↑Fri Jun 07, 2019 18:36 But would you prefer directions like 'A14 to Cambridge, M11 to the A1, then A14 to the M1, then M6 to Birmingham', or 'A14 as far as it goes, then M6'? The specific numbers don't matter to most people (although it makes a difference to people whose job it is to talk about them), but the actual assignment of them makes a great difference to the usability of the system.
Does it really affect the usability of the system? In what way? How many people avoid the A417/419 because the numbers are confusing? Or the A2/M2? I would suggest that the failure to differentiate properly between A roads which are high quality dual carriageways and terrible barely improved A roads is a bigger problem in terms of system efficiency
Before SatNavs, when planning a route, you might get out the atlas, and look at it, and see that the A14 ran all that way, and decide that it is the primary route, so you want to follow it. If they had done the same roadworks, but not renumbered it, some people might have looked, seen the A45 pass Cambridge, and follow that, then cross country to Bedford and the M1 instead. The numbering is part (not all) of how routes are suggested, to get drivers to follow long distance roads and avoid issues you might not see on a map. Then there is the choice and length of numbers. One route my mum does is M180-M18-M1, which in some people, consciously or otherwise, helps to suggest the driving from feeder roads to an arterial, and gives confidence in your progress.
My point was not that road numbering is the be all and end all, but that it is one of those design decisions in the world that has a great deal more utility than it might appear, to many people, and while many don't think about it at all, it does matter to them. There must be a reason most countries have decided to number their roads, and think about the system they choose. If it didn't have benefits, the expense wouldn't be worth it. It's like the classic door with a big handle, and the word PUSH above it. It's badly designed, because the handle suggests pull, and the dissonance causes issues, but you could easily say that because it has the instruction on it, complaining about the handle is stupid.
It's not a replacement for designing, building and maintaining the roads better, but choose the right number, and the roads might work just a little better.
For this road, in particular, I like people giving there ideas for the renumber, if it was ever to be done, now is the time, when most of the signs on this stretch will be replaced anyway. But it does have disadvantages, since it would mean changing a lot of other signs not on the new road as well, and I feel there should be a compelling reason to do it.
