Bay Area peeps, I starting building a BART Live map that shows where the trains in real time https://bart-view.vercel.app/
What do you think?

Live map and departures for Bay Area Rapid Transit (BART).

@bgmunny wow, this is fantastic. I will take a closer look in a few. Thank you!

@bgmunny I think this is very cool! It's clear, simple, and visually compelling.

In your shoes I might separate the tracks going different directions; the "collisions" make me somehow uncomfortable. And you could try using use some animation to give continuous motion for things that are in motion. You might also see what turning the station labels into mouseovers does. But that would shift it away from practicality and toward art, so it depends a lot on your goals.

@williampietri Oh that's an interesting point about the collisions. I'm worried that adding two tracks might make the map more difficult to read. Maybe I can offset the markers a little bit depending on their direction though.
Definitely plan to animate the moving trains eventually, and also add station information.
@bgmunny Ah, cool. To be clear, I was suggesting removing the station labels entirely in favor of mouseovers. So the default display becomes more about lines, static and moving. Just an idea, though; it might not be where you want to go.
@williampietri I see, actually, I started work on some UI switches to toggle the labels on and off. I do think it's cool/useful. Those UI elements were causing the page layout to get all weird though. I need do some debugging/testing, but I think it's doable.

@bgmunny I think it looks awesome. If I were going to distribute it as a working app I'd try to make it work for color-blind folks but I have no idea how I'd do that with the otherwise brilliant use of colored directional triangles.

Also I'm reminded that in 47 years of using the fremont station I still think of it as a terminus and should ride to the new stations just to see.

@geographile That's a good point. There's usually 2 approaches to make diagrams more color-blind/color-deficient friendly: differentiate things by brightness, or differentiate them by shape, rather than by color. The former would not be that hard to implement. I will add it to my todo list.
Haha, I'm really looking hoping BART reaches Diridon station before too long. That would be so useful.
@bgmunny Need to make the yellow trains darker in light mode. And maybe make the tracks lighter in dark mode.
