multiple points. This was already handled when the roads went between
the same intersections, but I found a case in Ballard where the roads
are just really close to each other. Screenshot diff empty in Krakow,
but still related to #243
- Cut off the one-way markings before the end of the road, to stop stomping over turn markings
- Draw turn arrows to every road, not each lane
- Only draw turn arrows when a lane is restricted from going to some
outbound lane. At most intersections, all turns are legal, so don't draw
anything.

that's a little trickier.)
_NOW_ regenerate all data! The only diff anywhere is the binary map
format, so there's confidence the last few commits haven't changed
anything.

charging experiments. This step just rearranges the data to define the

one of the outbound roads. This was motivated by one particular example
in downtown, and per screenshot tests, doesn't have regressions
elsewhere. Also improves a few cases in montlake.
when allowing a car to start a turn. It causes

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They became out-of-date a few weeks ago when I cleaned up the OSM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.
extend short borders, but it can't be done in convert_osm clip. has to
happen later when trimming and making intersection geometry. too much of
a headache right now.
west seattle and krakow still broken because of short borders.
