by chance in #870.
A vehicle exits a driveway and blocks a lane on its way out. When we try
to clear the static blockage, the queue calculation recurses to resolve
distances on the queue where that vehicle is entering. But since we
temporarily don't have the car in the list of cars (for the borrow
checker), it was crashing.
One of those "2 hours to figure out, 30 seconds to fix" bugs.
Transit stop IDs previously were tied to LaneIDs, but those can easily
change with edits to the number of lanes on a road. We still may need to
re-snap transit stops (if the driving position or sidewalk changes), but
this prevents one more common type of problem.
This requires regenerating everything, since it's a binary schema
change...
And clean up some other things that RDP does better.
Fallout from regenerating everything:
- Enfield borough crashed, so removed it
- All UK scenarios are now much bigger, due to the changes in #853 being
picked up
- Poundbury gridlocks now due to that
too far, by not trying to trace near railways or cycle-only
bridges/tunnels. This is an imperfect heuristic, but it makes
significant progress in most maps.
intermediate results can't be turned into a polygon. It'll break
something later. #841
There's a particular bug where a perimeter can be turned into a polygon,
but after collapsing internal dead-ends, it can't.
If we don't do this, the LTN select boundary UI crashes, and reasoning
about block -> neighborhood mappings gets very hairy. I'd like to
address all the root causes of failing to make a polygon, but until
then...
TRADE-OFF: it _really_ slows down the select boundary UI.
along the perimeter of broken intersections.
There are cases where intersection geometry is a little bit broken,
jutting out a bit and touching a road. It's more robust to still produce
a reasonably shaped block in these cases, instead of totally give up.
Visual inspection and the goldenfile VASTLY improved!
1 lane (usually a cycleway or footway). This correctly produces a few
more blocks in some maps -- as the goldenfile diff (and manual
verificaton) shows!
Also allow jumping from LTN browse to debug mode, to conveniently work
on blockfinding problems.
* add turn_on_red config option which is false for nyc
* when making stages, don't add movements that don't share a stage with a protected movement
* Fix a renamed DirectedRoadID field from
cb3693bd7a and the new turn_on_red field
in the test crate
* Update all map config files with the new option
for x in importer/config/*/*/cfg.json; do
cat $x | jq '.map_config += {turn_on_red: true}' > tmp
mv -f tmp $x
done
(And then undoing NYC)
* turn on red banned on all non-us maps
* regenerate all maps

near OSM highway=crossing nodes. #795
Not enabled anywhere, because it doesn't seem to produce good results.
Possibly footway=crossing ways need to be used for this as well.
Had to regenerate all maps, since the binary format changes.
to further organize them by purpose, but for the moment, two problems:
1) the city picker UI is getting way too crowded
2) on native, the initial download is up to 145MB
Removing:
- the 3 Aurora maps and Green Lake, added for the ARC workshop, but no
longer the most active of collaborations
- Ballard is now subsumed by central Seattle -- the only advantage would
be keeping its full scenario of walking and transit trips, but the
simulation is horribly gridlocked there anyway
- the Rainier Valley map, originally meant for an SNG traffic light
timing study
- the larger udistrict map
- Procedurally generate houses there, so the automatic travel demand
model doesn't produce totally silly patterns.
- Disable parking
- Allow vehicles to enter the intersection even when it looks like they
might get stuck; this lets the default scenario complete without
gridlock.
- Prebake the scenario, so a researcher can make edits and use all of
the A/B testing data viz.
The home-to-work scenario produces laughably bogus patterns... everyone
working at Bank Sepah.
any trips snap successfully to buildings, so we wind up with 0-trip
people that break some UI logic.
Reimported all actdev scenarios. Hopefully there weren't any cases like
this in the Seattle data, but I'll do a full regeneration later tonight
anyway...
The deadend trimming is too enthusiastic, getting rid of some unsnapped
cycleways and things connecting to the map border. Will iterate on it
this week; net benefit for now.
