36ef6d6b34 When merging blocks, try reversing the order of one. Otherwise, the
current mix of clockwise and counter-clockwise blocks don't combine.

99747ff34e Make the LTN tool more robust to broken blockfinding. #841
Try the cheap validation first. If it breaks, fall back to the expensive
version.

cb6a628149 When the pre-trimmed endpoint for a merged intersection is inexplicably not on a road's center line, just skip instead of crashing. This allows us to roll out the dog-leg intersection merging for many more maps and see pretty much universal improvement in map geometry! #654 [rebuild] [release] 2022-02-20 18:01:30 +00:00

6a5366292f Make editing maps with transit stops a little more resilient. #372
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...

4d9074571b Regenerate 4 London maps. They wound up with parking lots and other
objects outside the study area boundary, because I changed the boundary
but forgot to first re-clip the .osm file. #794

9054666a0b Use RDP simplification to road center-lines when we glue them together after collapsing degenerate intersections. This is a followup to #833.
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

e5704f4a6d Prevent many cases of blocks with overlapping geometry or that extend
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.

dfbd9785f3 While merging adjacent perimeters for the LTN tool, don't proceed if
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.

cb3138dbfe When turning a perimeter into a block polygon, don't insist on tracing
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!

2356cee1db When tracing perimeters, allow doubling back at a dead-end with exactly
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.

No right on red (#806)
* 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

fd10ea74dc Add configuration to filter the auto-generaed crosswalks to only exist
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.

be9ba5a80e Clean up the absurd number of Seattle maps. Ideally we'd have some way
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

2288b0d42a Add a smaller study area in Tehran.
- 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.

df242871b5 Fix actdev crash -- some people in the imported scenario data don't have
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...

c98b4f293e Regenerate all maps after last few changes. Split out the actdev scripts to more easily regenerate actdev scenarios. This is necessary if map intersection IDs change, for instance.
Rainier Valley starts crashing in the simulation! Not sure why the
regression happened, disabling for now, will look into it later.

ffcf0a8d66 Fix a bug in transit snapping introduced by 163244ace9. Regenerating all maps, also bringing in a Tempe OSM fix...
The deadend trimming is too enthusiastic, getting rid of some unsnapped

this week; net benefit for now.

db435cd56d Use the quick fix to https://github.com/easbar/fast_paths/issues/34 to
dramatically improve time to import and edit maps.

The fix helps all maps that use extremely high edge weights to prevent
people from cutting through private roads. There may be a more robust
fast_paths fix later, but I want to reap the benefits for tomorrow's
release.

The dramatic numbers:

- importing huge_seattle: 893s down to 108s
- editing huge_seattle: 102s down to 19s

Query speeds didn't appear to substantially change.
