https://github.com/dabreegster/abstreet/blob/master/docs/new... Biggest barrier is lack of trip demand data. If you come up with how many people leave from building1 to building2 at time T using some mode of transport, then this can work.

In theory, https://github.com/dabreegster/abstreet/blob/master/docs/new... . There are a bunch of unsolved problems -- for example, most places in OSM don't map on-street parking, so there won't be any. For Seattle, I'm inferring from an…
