Title: MD: Truncating MD 778 to MD 261
Post by: Markkos1992 on November 30, 2021, 07:26:29 pm
I noticed Sunday that I did not see signage for MD 778 going north of MD 261 (https://www.google.com/maps/@38.736723,-76.5900709,3a,75y,221.91h,81.25t/data=!3m6!1e1!3m4!1sJ71XP3AUtzbbTqqiwkkSfg!2e0!7i13312!8i6656), and the 2019 HLR (https://www.roads.maryland.gov/OPPEN/2019%20Anne%20Arundel.pdf) seems to agree, so I think that MD 778 should be truncated to MD 261 on its north end instead of MD 2 (https://www.google.com/maps/@38.7470427,-76.5922284,3a,75y,186.91h,85.74t/data=!3m7!1e1!3m5!1shBrcskR8W7piyNPsTHu2RA!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3DhBrcskR8W7piyNPsTHu2RA%26cb_client%3Dmaps_sv.tactile.gps%26w%3D203%26h%3D100%26yaw%3D222.50584%26pitch%3D0%26thumbfov%3D100!7i13312!8i6656).

they also removed a MD 778 north shield from WB MD 261

A couple other label suggestions based on this:

MD 2:  MD778_S>-MD778  (only intersects it once now)
MD 778:  MD2_S>-MD2 (only intersects it once now as well)

I would think that both would eventually end up in yakra's "EXTRANEOUS_LABEL" Datacheck that is being worked on.

Huh? ???

I stated that because the suffixes for these labels are not needed anymore as MD 2 and MD 778 only intersect once now.

I'm not working on such a datacheck though. ;)

Maybe you're thinking of some other stuff I mentioned a while back (https://forum.travelmapping.net/index.php?topic=4598.msg25463#msg25463) that's kind of in the same ballpark, but not this exactly. A little work on EXTRANEOUS_EXIT in datacheck form was done, but it's buggy & partially complete; otherwise these were just done as shell scripts & set aside as ideas for the future.
• EXTRANEOUS_EXIT is for detecting I-95(42) labels that can change to plain I-95 -- parenthetical suffixes rather than underscored.
• UNIQUE_SLASH_SUFFIX only looks at labels with slashes, applying these (https://travelmapping.net/devel/manual/wayptlabels.php#avoidsuffix) rules (https://travelmapping.net/devel/manual/wayptlabels.php#identicalmultiplex).

A datacheck like this one would, in its simplest form, produce a lot of false positives due to multiplex splits.
For example, ME11 has only one ME4_* label (https://travelmapping.net/hb/showroute.php?r=me.me011&lat=44.097972&lon=-70.231218&zoom=14), the other ME4 split being US202/4.
From there, introducing a need to look at HighwaySegment::concurrent lists or Waypoint::colocated lists makes the complexity ramp up pretty fast.

^Yes, yes I was thinking of that.  Everything mushes together in my brain after a while.

Good call. Should have done this in the first place, whiffed on it because truncating MD778 was the last update I made before going to bed last night and I was already fading, clearly.

Handling this locally now, will go live once I get a chance to address all your other remaining comments which should be sometime next week after I get home from this combo business/clinch trip. (Incidentally, I am in Maryland currently!)

Yeah, and I am planning on another Maryland trip Saturday.

For the record, I recommend focusing on Maryland before anything I post further in regard to Arizona.
