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

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 reading could be helpful. Or if you keep that on a separate p

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:

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 was hard to influence real d

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

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 get longer and more detailed to counter this; expressin

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, given the same input and code, and calling out to an extern

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 p

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 lock and prevent conflicting movements. A huge intersection

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 resources. A/B Street's simulation is m

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 represent the transportation network in great detail. This is a

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" section. How would multiplayer synchronization fa

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. This article explains how to model vehicles and pedes
