Responding to items brought up in this thread, and stuff I noticed in the process. Not doing any full-fledged in-depth review of course.
QC185/TCH
...
- is the QC185/A-85 point in the right place? Is this one-point-per-interchange
Assuming you mean A-85_S, it's that we decided in CHM days after the painful Arnprior experience with ON 17/ON 417 to end Canadian freeways at the last interchange, unless there is an intersection point where we could place the end (as we did with the other A-85 segment, where there is a Fin A-85 sign at 3e Rang). There is signage indicating that A-85 restarts before sortie (exit) 47 in St-Louis-du-Ha! Ha! But there is no intersection between there and ChSav. ChSav has signage indicating that QC 185 extends east of there, and A-85 doesn't end there, for now.
That all being said, it looks as if Exit 47 would be better served as a "misbehaving parclo" to the west.
QC236: ChStLou_E -> ChStLou_N?
QC309: Is ChLaj semi-important or likely to be used by travelers? If not, Chemin du Rubis to the east would do a better job of shaping.
QC340: The hyphenation at
BoulCitJeu_E makes things a little quirky, but I think Si's original recommendation of
BoulCiteJeu_E is arguably a better option.
QC342: MteeBStTho ->
something elseQC344: add point at BoulGau as leads to A-640 exit 26
QC360
- QC138_A, QC138_B, QC138_C, QC138_D -> QC138_Que, QC138_W, QC138_E, QC138_Che ?
Despite the change having already been made, IMO with these point all connecting to the same chopped route, _A _B _C _D might be the less ambiguous option.
QC366: *OldA-5_S -> *OldA-5
QC369: RueSei is placed on Avenue Sainte-Therese rather than QC369.
QC395
- point for 1reAv in Amos (links to QC109/QC111 point)
At first I thought that was a typo, but nope,
it's signed that way!
Looks like
premier and première have their own suffixes, not unlike English's "st" (& "nd" & "rd") vice the usual "th".
QC138Mon
- USA/CAN is slightly off (also NY30)
The point is a bit N of the border per OSM, and a bit S per ESRI.
What do NYS shapefiles have to say?
The MilepointRoute2015 and Cities_Towns shapefile sets are at different scales / different levels of precision. Consequently:
• The arc representing NY30 crosses the edge of the Constable polygon
here, corresponding to where OSM has the border.
• The northernmost extent of the NY30 arc is
here, fairly close to where the current waypoint is, but still a bit south of where ESRI has the border.
In light of all this, I'm fine with going no-build. Or I could change to something closer to OSM if Oscar wants to.
A-20(63) -> 4
Oh dear. And since this qualifies QC138 as a route with its own exit numbers, possibly A-20(64) -> 64(20)?
Does this happen elsewhere in the system?
Add a point in the middle of the rectangle bounded by Rue Notre-Dame Centre, Rue Saint-Georges, Rue Royale, Rue Saint-Roch -- leads to A-40 exit 199 and helps clarify the routing in the area a bit.
- QC360_A /_B /_C /_D -> town suffixes or (B and C could be directional suffixes as concurrency split)?
See above
QC221:
- NY276 -> USA/CAN
GMSV indicates NY 276 takes a sharp turn east just south of the border, as confirmed by the border monument and fence just north of the road, rather than connecting to QC 221 (you can cross the border at that point, but on about 0.01 mi. of pavement that isn't part of NY 276) . I would rename and relocate the NY276 point, so it doesn't synch with the corresponding QC221 point for NY 276. @yakra, do you agree, and think the QC221 point should be renamed?
I see that you've made the the corresponding changes on the QC side, and marked a FP NMP. The point on NY276 isn't off by
much, but can still use a tweak, so
it gets one. I can take care of changing the nmpfps.log entry along with. Got some other stuff to flag in NY anyway. Can't find a known road name for this short connector
to QC221 -- so with a quick check of the manual, it looks like
ToQC221 is the way to to go.https://github.com/TravelMapping/HighwayData/pull/3914Also, the points for the north end of US 11/south end of QC 223 look off relative to the border as shown in OSM, and to a lesser extent in ESRI (including its satellite imagery) and HERE. Do shapefile data support leaving the border point as is?
Similar situation to NY30. I get coords
here and
here.
Ferry names: I'd say, if there's no official name to use, just the unadorned
Fry is sufficient.
Speaking of that area, I noticed QC 105 has separate points for A-5(28) and ChValWak. Shouldn't that be a one point per interchange situation? Someone traveling northbound on QC 105 wouldn't even drive the road between those points.
For whatever reason (maybe someone who traveled QC 105 before A-5 was extended that far), someone is using the ChValWak waypoint.
If there were another numbered route involved here I might think differently, but... I'd recommend folding ChValWak into A-5(28) as an AltLabel.
The traveler is 7_8, whose clinched segment leads north.BTW, there are possible isolated segments of QC 138 in La Romaine (at least from the harbor to the airport), Chevery, and Pakuashipi, some of which reportedly are signed and one of which (Chevery) is in OSM. Everything I've seen in MTQ online data shows route numbers for those segments other than 00138, so I'm inclined to treat them as "future 138" at most. @yakra, do the most recent shapefiles say anything more?
Nothing more recent. Still working with data from 2016.
GeoBase seems to have slowed down big time on, if not forgotten entirely, updating the NRN shapefiles. NS & PE were updated in 2018; everything else...
(Maybe I gotta dig up a new link? I've tried occasionally, with little success...)-- Any comments on how I dealt with the messy A-25/A-440/QC 125 interchange in Laval?
I made sure to have a look in the HDX before reading the rest of your thoughts, to see what solution I'd lean towards without any pre-bias.
Aye Caramba.
Moving the waypoint to the A-25/QC 125 intersection from the middle of the A-25/A-440 triangle better reflects that the interchange serves QC 125 and not just A-25 and A-440, with direct ramp connections from QC 125 to A-25.
My first thoughts were that this might lend itself to a 1PPI solution. The triangle, along with the QC125 at-grade junction thrown into the mix.
But I'm not sure about routing QC 125 via A-440(34),
What struck me was the angle of the final segment of A-440. Judging by a numbered Exit 34 being where it is (I'm not checking GMSV right now) it looks like A-440 heads south on the west leg, from the A-25 split at the N end of the triangle. The route trace looks awkward, but in a sense checks out in that A-440 continues to A-25, and that's where A-25's point is.
when northbound QC 125 traffic goes east of that point (southbound QC 125 traffic has to go through that point, to connect to the QC 125/A-440 concurrency).
Nonetheless I think 1PPI may be the cleanest -- a "correct by way of vagueness" -- solution here.
With the Masson/Marcel-Villeneuve intersection right on one edge of the central triangle, you could let this weight your judgment of where the triangle's center is.
I took the I-97@7 example to extremes, and considered where traffic would go if the thru lanes weren't available, if one were to exit & re-enter the highway. The inside-the-triangle, left-turn-ish movements would pass thru that intersection. The outside-the-triangle, right-turn-ish movements would be a little ways out on each leg.There's another situation like this in TX, with a central ramp triangle, and a junction of at-grade routes right on one of its legs.
The main difference is there's not the added complication of a surface route
joining/leaving a freeway via some funky ramps that QC has. (But there's still access between all the things because frontage roads.)
Here's how I handled it:
ISTR pondering whether to slide the point a bit more SSW, and could just as easily have done so.
I've yet to read http://forum.travelmapping.net/index.php?topic=2038.msg18656#msg18656 onwards. Done. No further comments.
