vnmct: Vietnam Cao Toc

[jayhawkco]

Finally got around to logging my travels in Vietnam.  When trying to log the route I took to Ha Long Bay, I got this in my log file:

VNM: duplicate label QL18 in vnm.ct09. Please report this error in the TravelMapping forum. Unable to parse line: VNM CT09 CT04 QL18

Fixed this.

Just a quick look...

https://en.wikipedia.org/wiki/Expressways_of_Vietnam#List_of_Expressways


CT25:
Should be CT27 according to OSM but CT14 according to GM and wikipedia
It misses a wp for the former or future? GSJ with QL27. Minimum a shaping point north of it should be added to distinguish from QL20


CT03:
Should be CT08 according to OSM and GM


CT37:
Should be CT20 according to GM and wikipedia


Wow, "great" challenge!

I mean, no useful source nor GSV to confirm if OSM or GM is right.... Just look at the 80km+ CT06 extension on OSM. Nothing visible on GM nor satellite view but GM routes traffic there anyhow. Is there a road or not?

Minimum, the freeway system (tier 1) has a length of 765 miles and has 3 travelers. So, I think the system is worth being reviewed and activated. But.... how?

Vietnam renumbered most of these roads relatively recently. I went with Wegenwiki, which used the official listings. I don't know if OSM (and good luck with GM) has updated fully.

The confusion is unsurprising.

Got it!

CT37:
Should be CT20 according to GM and wikipedia

It seems that CT20 was renamed to CT37 in 2021: https://www.wegenwiki.nl/3rd_Ring_Road_(Hanoi)

Goodness...

16km have been opened yesterday. The remaining 81km should be opened in September: https://www.skyscrapercity.com/threads/1464920/post-179723687
