abstreet

I was excited for awhile about this project, but sadly it is not maintained. For scratching the same itch (for me it's traffic mainly that is somehow interesting) you might want to look at https://github.com/Uriopass/Egregoria or for the tighter focus on traffic, https://github.com/a-b-street/abstreet .

This is super impressive! I'd agree the open-source tooling isn't there yet, but it's coming in a few places. I started a 3D street visualizer but it's only at the scope of a few blocks at a time, not as large as a city area although we'd like to get there someday: https://github.com/3dstreet/3dstreet/ There's also https://github.com/a-b-street/abstreet for larger area simulation but with less visual fidelity

A|B Street does some of that, but it is not a game: https://github.com/a-b-street/abstreet

Super awesome! I like how you just color roads to show time. When you calculate polygons to try and cover the whole area in some 5-10 minute bucket, you can wind up with all sorts of odd holes far away from roads. Keep it simple. https://github.com/a-b-street/abstreet/pull/1075

A/B Street seems like a good candidate. https://github.com/a-b-street/abstreet

Related project that goes more in depth with modelling a whole city section (with focus on realistic traffic patterns: https://github.com/a-b-street/abstreet - Transportation planning and traffic simulation software for creating cities friendlier to walking, biking, and public transit Very interesting project which I played around with a bit and tried hacking on it to add cities I live in, but the slow Rust build times makes it kind of chore so never really managed to create something good with it.

For traffic simulation there is https://github.com/a-b-street/abstreet which is very impressive project.

I haven't given any love to the poor tutorial mode in ages, so I'm not surprised you found a bug. Please file an issue (https://github.com/dabreegster/abstreet/issues) and describe how to reproduce the problem. If you can open the browser developer console (Ctrl+shift+I in firefox), often the last part will be really helpful.

Especially if you're trying to clip your entire map to some boundary, rendering the ocean is hard. https://github.com/a-b-street/abstreet/issues/32 has some examples of "flooded" maps when the heuristics get the inversion wrong. https://github.com/a-b-street/abstreet/blob/9761373c4b215485... is my incomplete attempt to deal with these partial multipolygons.
