Thanks for your answers, and that link related to highlighting routes. It's led me to
your post in Parking Lots are Glorious, and I am geeking out right now over the city map image you posted of Tucson

. More on that later!
Make navigation inside cities easier.
Yes. That is a goal I can totally agree with. And I see now how your C/FD would help with that, since there's no IRL equivalent to ATS's city maps you can markup/annotate.
My map-related project's original motivation was to make navigation on freeways easier; specifically, I want lane guidance, because I've missed my exits
so many times while driving through complex junctions, and I don't find the guidance that ATS provides all that helpful. I'm sure it's a solvable problem: given a calculated route, examine the junctions along that route, look at the AI Curve data for a junction, and infer the total number of lanes plus the possible lanes you can take to navigate to the next node in your route. It's just "a small matter of programming"

.
The desire for lane guidance then led me to ask, "how hard would it be to create Google Maps, but for ATS?". So, a telemetry-plugin based webapp that you can do route planning with, and search for nearby facilities or other points of interest along the way. The answer to the "how hard" question is, of course, "very hard

".
One of the unknowns I've been thinking about in the back of my mind is, how can we get the data needed to label freeways, exits, and roads? While lane guidance is nice, lane guidance that tells you where a lane leads to (like I-10 East, or Congress St) would be even nicer. I'm guessing from your Tucson map, you've already explored similar/related problems... especially if it was generated semi-automatically. My attempt at recreating that map looks like:

Labeling freeways, exits, and roads is probably going to be a manual endeavor (probably need to build a Map Editing tool, similar to the ones used when working with OpenStreetMap data)... unless I try scanning nearby road signs and trying to guess what they mean and use that to annotate the ways. Or training an AI model to do it, haha. But maybe that's a "version 3" or "version 4" task. For now, I'm just concentrating on getting a browsable, decent-looking vector-tile-based map up and running. Basic routing with lane guidance is next. Lane guidance with richer info about where those lanes leads is probably too far in the future for me to worry about.
