Quite cool to see this space being explored! https://github.com/headwaymaps/headway is another related project.

This is incredible. I remember failing to hunt some down earlier, but does anyone know of really detailed plans or 3D models?

I stayed there about a year ago, and wrote a bit about it with some photos. Just search this page for "Chungking": https://dabreegster.github.io/prose/dec2023/pt1_hk.html

Just want to plug Pantheon as a TV series exploring this idea with excellent storytelling. ( https://en.wikipedia.org/wiki/Pantheon_(TV_series) )

This is super cool, thank you for building it! Two small UX ideas: - a scrollbar and search for the Online Library would be helpful - switching difficulty levels in the middle of r…

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 …

Hi! https://a-b-street.github.io/docs/project/history/retrospect... has a summary of where the project went. The original scope of the traffic simulation was too grandiose, and it …

I love this series. It also reminds me a bit of https://unsongbook.com -- another beautiful work of creative writing combining technology and magic.

Market pressures from the open source world ;)

One of the authors of https://github.com/a-b-street/osm2streets here. If you're interested in improving the quality of the lane rendering, please get in touch on the repo! https://…

We're working on rendering more detail about roads for high-zoom cases: https://github.com/a-b-street/osm2streets . Try https://a-b-street.github.io/osm2streets/?test=st_georges_cy…

In my experience, the published paper is super vague on the approach, and implementing it without further references is really hard. I'm not necessarily arguing that papers should …

abstreet.org has an offline import process that combines data from OpenStreetMap, city-specific GIS datasets, and elevation into a single file. The process has to be deterministic,…

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 descri…

Hmm, I guess I never checked satellite for that example. Part of the motivation there was improving the simulation. While vehicles are moving through the intersection, they grab a …

Thank you for the industry insight! I'm definitely not trying to match the degree of realism and calibration with the professional stuff -- there's no way I could, without way more…

Right, from https://supaplexosm.github.io/strassenraumkarte-neukoelln/po... (translation https://translate.google.com/translate?sl=auto&tl=en&u=https... ), there was an extra curb …

Just this morning I came across new work from the Berlin OSM community: https://supaplexosm.github.io/strassenraumkarte-neukoelln/?m... The end-game isn't in sight. We (data consum…

And in case you're interested how the traffic simulation part works in detail, but missed yesterday's post: https://news.ycombinator.com/item?id=28553654

A/B Street is an open-source traffic simulator that lets you edit roads and intersections, based on OpenStreetMap data. But to even do that, first we have to geometrically represen…

Thanks for reading! I think rendering vehicles following each other would still require asking the simulation for positions, unless you replicate the logic in the "Exact positions"…

Have you ever wondered how a traffic simulator like A/B Street works? Simulating thousands of trips through a city faster than real-time can't be done in 0.1 second increments. Thi…
