 Any thoughts? Anyone fancy following it up?


 Actually no, the NCN13 route _IS_ down the A13! Bizarre but true..

 It skips off for the flyover at Gallows Corner in Romford  maybe one or
 two other side jaunts, but basically you're on the A13 from quite well
 into London (East Ham or so) until Basildon, there are occasional red
 stickers to prove it  a marked cycle lane on the A13, complete with
 3-lane dual carriageways  national speed limits.

 You get crossing places marked at the slip roads, not usually with NCN
 stickers just white paint.

 I have seen the occasional cyclist mad enough to use it too!

 I'm not absolutely certain of the routing onto the A13 at the Basildon
 end, as it just might go down Southend Road Corringham into Stanford, at
 least one way, but I think it doesn't. It does cross over the A13 to
 Southend road on a bridge, One Tree Hill, but then could back-track to
 8-Bells roundabout, or do the Southend Road route, the signs peter out
 just where they might be useful.

 I wondered about this before I tagged it but I double-checked it,
 because it seemed so daft, and the signs, as they say, were there.


 I have cycled sections of the NCN13 from about Dagenham Dock into 
 London. There is a cycle path on the side of the road (often 
 segregated by a small bump kerb and the path is on both sides of the 
 2-4 lanes in each direction) and so in that way it is quite safe. Not 
 cycled further west though. Where I have the data I have been trying 
 to get the parallel cycle path added to OSM as whoever added the ncn 
 13 to begin with just added it to the trunk road's main carriage way 
 and even I really wouldn't want to cycle along the A13 for any great 
 distance! Also the way that you join from side roads can be a little 
 different in many places.
 
 The information on Sustrans mapping and OSM mapping is wildly different 
 for NCN13. I am of course not proposing that we use Sustrans mapping 
 information as a source, but as a 3rd party check it seems to through up 
 some significant questions about trunk road sections.


It's worth a check, I only found a few signs  miles of cycle lane. In 
particular I think it was Gallows Corner with a sign where the flyover 
has a no-cycling sign  there was a notice - they've just done a lot of 
work on that though.

It is however the case that most* of the A13 in Essex has a cycle lane 
clearly marked  yes, you'd be nuts, and yes, the council did it  they 
don't cycle.

More recently the Thurrock council have added a cycle path along the old 
A13 in Grays which would make a lot more sense to use, I did wonder 
about tagging it that way but there is no NCN signage  it felt very 
unilateral so I didn't.

 Maybe we want different policies for different areas and different kinds of

 For example once all the roads are mapped we freeze the roads, but we allow
 free changing of street names until they reach a freeze point.

 Here in Korea I just want data and the more the better. In downtown London I
 would assume all the roads can be frozen
 except for major construction.


 That would be a very bad assumption, as every single one of our
 continuing London mapping parties shows. I'm constantly moving and
 renaming roads as the data we get becomes more precise.

 Nevermind the more technical issues such as adding and connecting
 roads to existing roads, or foot paths, or cyclepaths, or any of the
 other stuff which might not be considered mapping the roads but still
 requires editing them.

I'm wondering whether some kind of Checking and Verification could be
done. ie A Live edit map that it what new edits go into, then a
checked map that people can say yes I agree that is what is there,
Anybody can sign any edit off just not there own... Of course this
causes problems with areas where nobody else goes But we should be
able to join the two maps together with some kind of overlay. If
someone is adding footpaths etc they should not be moving major roads
very far. We could even let people sign there own edits with the
GPS trail it came from, and hence see that someone went there and saw
it. Rather than just made it up. So its either checked by the GPS or
by another mapper.
