[Talk-ca] Trans-Canada Highway research

[Pierre Béland]

Sur la page wiki https://en.wikipedia.org/wiki/Trans-Canada_Highway, on voit que des panneaux Transcanada sont ajoutés sur le côté de la route. Cependant, au Québec comme en Ontario, les panneaux de navigation au-dessus de la route ne font pas de façon générale référence à la Transcanadienne. 
Comme le dit James, la Transcanadienne, c'est une méta-donnée. Une relation de type route permettrait de décrire ce réseau.  
Il serait aussi possible d'ajouter une référence à la Transcanadienne dans la clé ref. 
Exemple ref=417; TC(TC pour Transcanadienne).
Exemple où trois routes partagent un segment, ref=35; 104; 133.
voir https://www.openstreetmap.org/way/128245108#map=16/45.3227/-73.2309
Au dela du rendu sur la carte, ces références sont-elles utiles aux outils de navigation routière? En ajoutant TC, est-ce que l'on indiquerait à chaque fois, 
Continuez sur la route 417, Transcanadienne ?  Le risque est d'ajouter de la confusion dans les instructions de navigation.
Quel est l'objectif de l'équipe de Telenav pour harmoniser les références à la Transcanadienne et  ajouter les infos proposées ?

No trans-canada naming in sight because the trans-canada is a meta road composed of multiple highways. See road sign in OSV.

The proper name for the highways that are under the Kings Highway system (400-Series included) is "Highway xxx" or Highway xx, with the exception of the QEW.  Highways signs and government data follow the same rules.
The Trans-Canada as a name/deaignation is almost inconsequential in Ontario and to Ontarians.

I disagree.  "Highway 417" is a low-value name, because the "ref" tag
should already contain the number, causing numbered shields to be
shown.  "Highway 417" is just a verbosification of the number.
"Trans-Canada Highway", however, is a real name; it belongs in the name
field.

This way, most maps would show both name and number.

To me, the (completely separate) issue is whether ordinary numbered
highways should have a name tag at all, "Highway nnn", or simply nothing
because "ref" takes care of it.  I've been able to find no guidance on
this, and I've looked.  I've been leaving "Highway nnn" in place when I
see it, which is most of the time.  But that's another discussion for
another day.
