Hi,
When mapping, I’d liked to add int_ref for the A1 motorway in Algeria … yep lol … the unique/single/only one, motorway in my country. Then started to look for a standard or equivalent international reference for A1 in Algeria but … found nothing !
So,
nat_ref=A1
ref=A1
int_ref=scoobyyy dooooooooooo !! ? 
Let me know if anyone of you have a source of information.
Salutations amicales.

I guess, it would be “int_ref=TAH 1”
(or should it be “int_ref=TAH1” ?)
Hi, thank you for the answer 
That’s not the TAH 1 (from northen Algeria to the South) that’s the Trans Sahara.
I’m talking about the Motorway A1 from eastern to western Algeria crossing Algiers the capital ;).

According to wikipedia “from northen Algeria to the South” is TAH 2…
Humm, you’re right ! It’s a part of TAH 1. Yep.
So, should I put int_ref=TAH 1 with space between TAH and 1 or TAH1 ?
Okay I follow this one like un Tunisia with : TAH 1 (spaced)
That’s a good question. European routes in OSM looks like E 40, while Asian - like AH1. How African should look - I don’t know 
Hello Xan_ua,
I have no idea since I never met any road sign on the motorway saying that algerian motorway A1 is referenced TAH 1 (spaced) or TAH1.
Something like what you pointed in Asia.

Anyway I tagged int_ref=TAH 1 (spaced) for the moment.
Thank you very much Xan_ua
