KY: Odd coloring on Bluegrass Parkway

[dfilpus]

The segment of the Bluegrass Parkway between 21 and 25 is colored Blue (Tier 1) instead of Teal (Tier 2). The rest of the parkway appears to be correct.

Hm. A real-world example of confusion that can be caused by rendering multiple polylines of different colors atop one another.
https://github.com/TravelMapping/Web/issues/198

Magenta = blue + red; teal = blue + green; mix`em together and the red & green add together to make a lighter blue: 100,200,200 & 255,100,255 average out to 178,150,228, which isn't too far from the 100,100,255 of unclinched blue.

If you instead look at mapcat's mapview (he has this segment clinched), it's still a little blueish but more visibly teal compared to I-65 a bit to the west.

See https://github.com/TravelMapping/Web/issues/198 for information about a first attempt at a fix.

Loading time is currently worse but the color is as it should be

See https://github.com/TravelMapping/Web/issues/198 for the latest on the efficiency fix for this enhancement.  The cost of the current solution to this is small compared to the other costs of loading maps with lots of routes.

Please try out mapview on tmtest.teresco.org for now, and I plan to add this functionality to the production version soon.  Maps with many routes are still very slow, but the majority is DB lookup introduced for better ordering of route lists (https://github.com/TravelMapping/Web/issues/276).

The fix to draw concurrent segments only once is now live on the main site.

[mapcat]

Is there a way to make the old process (drawing multiple lines for concurrencies) optional? I miss being able to detect concurrencies of different tiers in mapview.

Possibly, but I think the best way to find concurrencies (or non-concurrencies) is to load up the appropriate graph in HDX.

Sorry, I should have mentioned that I was planning a trip, not looking for errors.

Got it - I added an issue so I can look into it when I have a chance.

If something were to be added officially, we'd probably want something a bit easier to see that what just happened to render under the old system.  They weren't always easy to see.  I do include concurrences in my .list file, both because it feels more "complete", and to simplify any potential future updates.  Fortunately, OSM is pretty good with them (unlike Google Maps), though they don't always know about things like truck routes.

[Jim]

One thing I want to get working (or working again - this might have worked in the past) is edge listeners to bring up popups with information about edges, that ideally should have concurrency information.  Would be part of https://github.com/TravelMapping/Web/issues/228
