[Talk-us] Thoughts on a standard "ref" abbreviation for PA Turnpike?

[Albert Pundt]

This would not involve adding ref=PATP to the PA Turnpike route relation.
However, thinking about it now, I think it should be added to the ways for
the sake of the Carto renderer. (I know, I know, tagging for the renderer,
but isn't Carto's use of ref tags for route markers the only reason the
tags remain on ways?) We'd need to be careful where we use PATP in
destination:ref tags, since the Turnpike shield is very rarely used once on
the Turnpike. For example, the ramps from the mainline Turnpike (I-276) to
the northbound Northeast Extension (I-476) should remain tagged as
destination:ref=I
476 and not destination:ref=I 476;PATP since that shield does not appear on
the signs. The only such use of a Turnpike shield that I know of is the
aforementioned example eastbound at Willow Grove.

"PA Turnpike XX" routes are an established type in Pennsylvania. Three
examples currently exist: 66 (New Stanton to Delmont), 43 (WV to Fairchance
and Uniontown to Jefferson Hills), and 576 (entire length, US 22 to Pgh
Int'l Airport). A relation tagged with network=US:PA:Turnpike and a
numerical ref value should trigger the use of the PA Turnpike XX
shield. This isn't simply a fancy label for a standard state route like the
yellow TOLL banners on I-376. They are treated as separate routes by
PennDOT and the PTC. Exiting US 22 near Delmont, signs say "PA 66 South, TO
PA Turnpike 66." Occasionally, an erroneous PA Turnpike XX shield pops up
for I-76, 276, or 476, but that's inaccurate. Also, the oldest part of PA
43 and the tolled part of I-376 (once PA 60) were in the past signed with a
white keystone simply saying "TOLL" at the top, but there are no remaining
routes signed this way.

On an unrelated note, thanks for linking that renderer. I used it to find
and fix some holes in PA's US 119 relation where it defaulted to using a
plain text rectangle since only the ref tag was present.

I'll start adding PATP to destination:ref tags now, but will only retag the
mainline ways if no one else has any objections.
