not split by direction. Update many callers, and lock down the
visibility of the old methods.
Tested a few maps manually to make sure there's no behavioral diff. Only
problem right now is the z-order of adjacent lanes covering up half of
the white stripe sometimes. Have some ideas to fix that later, and not
_super_ important in the meantime.
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
just does Dijkstra's. This has a few uses:
- When you import with --skip_ch, the resulting map will still work,
just more slowly
- For congestion capping experiments, we sometimes want to route around
a zone. Regenerating the contraction hierarchy for every combination
of zone being open/closed is likely more complex and expensive than
just falling back to A* for trips that cut through at least one closed
zone.

a zone per hour. This is part of support for some kind of congestion
charging experiments. This step just rearranges the data to define the
cap and makes a UI to edit it. Not enforcing the cap yet.
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They became out-of-date a few weeks ago when I cleaned up the OSM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.
OriginalBuilding was to refer to buildings in a stable way across
different maps and across OSM updates. Recently, OsmID and friends
appeared. The double layer of wrapping is an annoying API.

of routes skipped because of edge cases, but now it's way more clear
how to work on those smaller problems.
