gbnb: Great Britain B Roads

[michih]

The system is in preview for almost six months now and Si has indicated it being ready for review. The system covers more than 18,000 miles and I've agreed with panda80 that we'll review it together. We'll likely start the peer-review by the end of the year.

ENG reviewer: michih (11,800mi)
SCT reviewer: panda80 (4,400mi)
WLS reviewer: panda80 (1,700mi)

I think that the source is this: https://www.sabre-roads.org.uk/wiki/index.php?title=Category:B_Roads (note: it's only indicates as A roads source on credits.php)

Anyone is welcome to post additional remarks to the system here.

B104:
SNChuSt_W -> SNCSt_W ?

I'm going to say no. The 'SN' is only there as there was not allowed to be two road names the same in the County of London (that became defunct in 1964) and is merely the 'Stoke Newington' place descriptor of 'Church Street'. This is in alignment with the manual's example of "Martin Luther King Boulevard becomes MLKingBlvd".

B125:
A12 -> A12/A102


B142:
A12 -> A12/A102

Given this sign on the A102 was going to be the mostly likely end of the concurrency split to show the A102 (much more important south of the A12 than north of it), but it doesn't actually have it, I have split the A102 instead.

[michih]

You 'have split the A102 instead'? Not sure that I get you right. It's concurrent to A12 here, it's not split. Do you wanna split A102 now?


B155:
A109/A1080 is off


B158:
A414 -> A119/A414


B159:
A112 wp is interesting. There are two branches and you've put the end point to the one which is one-way only. It seems that both are dedicated. Shouldn't we move the wp to a position between both of them, still on A112 route, like A193 on B143? Or into the triangle (I don't like it)? At least, the end point of the northern branch would be better than the southern one.
I'd like to know how we wanna deal with this before I continue the peer-review. Thanks.

I've split the A102 - one bit north of the A12, one bit south. They function as two different roads and, since the A12 'uselessly' extended along the former motorway section of A102, might as well be different roads. I'd only kept them together as I assumed that the A102 was signed at Hackney Wick down the A12 like 'Blackwall Tunnels (A102)'. The concurrency changes dominant routes too - the A106 (from the A12 northbound at Hackney Wick, it's signed as (A102) - ie not the A102) as well as the A12 are the dominant routes - which is something that, when I find, I break a route up if I've not already - unless I find exceptional circumstances, like the concurrency being signed (eg The A10 around Cambridge).

Should point out - joined up along the A12 the route is 6.82 miles. The northern section is 1.02 miles, the southern section 3.00 miles. So 41% of the route is concurrency on a unsplit route.

Moved it to the northern one, which is two-way. Treating the one-way spur as a slip lane.

Does not exist between A222 and A232, split route

Article doesn't suggest that at all - OSM (wrongly) does. However, as it's concurrent with 3 A roads in-between A222 and A212, so splitting anyway.

Yes, sorry. I misread the A2039 thing first. Then, I was not sure and thought it's better to let you check it than ignoring it

Move SheGate to the junction with Fife Road

It's arguably less than the width of the road, but no. The gate is where the route disappears, not the junction with the minor road.

Unsigned spurs don't get added.
