when allowing a car to start a turn. It causes https://github.com/dabreegster/abstreet/pull/276#discussion_r470269394 and also the lakeslice scenario to gridlock (a regression that began a few weeks ago). But keep the flag on for now, to keep the montlake scenaro running at least. https://dabreegster.github.io/abstreet/trafficsim/gridlock.html has notes about the many different causes and in-progress fixes for gridlock. This experiment hasn't been explained very well yet, but roughly it treats a cluster of traffic signals as one, so that once a vehicle gains access through the first light, they guarantee immediate access through the entire sequence. This interacts with the "don't block the box" behavior (don't start a turn if you might get stuck in the intersection) strangely. While attempting to get this rollback to work, I also had to manually redraw the traffic lights for a few manually specified intersections. They became out-of-date a few weeks ago when I cleaned up the OSM geometry upstream and the referenced IDs changed, and I hadn't bothered to re-time the signals. Luckily, with the new multi-signal editor, redrawing the timing was much easier than originally! Regenerated all data and lots of bus routes vanished. Plan to get back to that project soon. |
