The roads that cross the light rail tracks wind up gridlocking horribly.
For this case study, we actually just care about Rainier Ave.
The scenario still gridlocks, but due to tiny traffic circles breaking.
Going to try automatically converting those to a single node.
to match.
Originally these were introduced to deal with merging intersections
between dual carriageways. But inadvertently, lots of left turns got
reclassified as u-turns. That's caused various headaches, most recently
the lakeslice gridlock. That's fixed again!
Fix a bug with the previous commit (lanes=1 on a two-way). Now regenerate.
... Unfortunately lakeslice now gridlocks due to a turn generation bug.
Temporarily removing the prebaked results there so I can push these last
few changes through. Will resolve this before the next release.
The Xi'an map isn't being regularly used, and it has some issues
(boundary is too large, OSM is missing buildings in most of the area).
The zcool font enables Chinese characters to render, but costs 6MB in
the binary files, slowing down wasm loading time. Eventually, we can
support async loading fonts and passing them to widgetry when loading a
map requiring them. For now, cutting down wasm size is a bigger
priority.
game wasm from 18MB to 12MB. Not bad!
* introduce "pill" to be explicit about fully rounded, vs a "None" radius
* no-op transition to CornerRadii
* popup button to spec
* restore "fully rounded" layout behavior
* use plain light to better show highlight
* persistent split to spec (for day theme anyway)
* remove night-theme colors for speed panel
* fixup docs for pill
* CR: remove unnecessary `row`

Also give living_streets in Krakow shoulders, so foot routing works
better there.
Now regenerate everything. Actually messes up routing for Trumpington;
71 cancelled trips up to 101. And have to intervene to keep lakeslice
not gridlocking, as usual.
For the moment, this is the simplest way to allow foot traffic. This
breaks down in places like
https://www.openstreetmap.org/way/49207928, where the road gets an
inferred sidewalk and the separate cycleway on each side is
bidirectional with shoulders on each side.
Down to 71 cancelled trips in the baseline for cyipt/actdev#32.
geometry), don't generate crosswalks or stop signs. In reality, these
usually represent the middle of a complicatd intersection. Ideally these
cases would be merged into a single intersection, but before that's
feasible, at least improve some of the inferred things nearby. #457
This will make it easier to visually track the progress improving the
import. Originally London was added to have one left-hand driving map
under the test, but Cambridge works for that too, and it also includes
separate cycleways.
Also fix a crash when trying to draw very very tiny arrows.
Small adjustments to unzoomed rendering and stop sign placement.
Regenerate all maps because of the format change, but only Cambridge
changes. Since we're doing this anyway, also pull in leisure=garden.
This speeds up scenario instantiation (because picking a bus to use can
be spread out over time) and is a step towards simplifying the spawning
code. Starting downtown goes from 12.8s to 2.2s.
All vehicles spawning at a border now regress to using the 1st valid
lane, instead of random. Now that the choice is made when the trip
starts, this could later be improved to pick the least loaded lane.
Now regenerate everything.
- stretch central polygon a bit to avoid crash when clipping
https://www.openstreetmap.org/way/511767781
- rename polygons ("center" to "huge", and removing the "leeds_" prefix
from the others)
- generate a region overview from the huge map
- only import/match collision data on the huge map
a hard error when they become out-of-date going forward.
Better heuristics make some of these unnecessary. And now the the JSON
files are in this repo, updating files manually when pulling down new
OSM data becomes less tedious.
Previously, dual carriageways (pairs of one-way roads in opposite
directions) mostly didn't get any signal templates successfully applied.
This change ignores outbound-only roads when applying the templates. In
one fell swoop, lots of previously broken signals along places like
Aurora Ave suddenly work reasonably.

Bring in fresh Seattle OSM with a few places on Aurora tagged, for
further experimentation.
Also, there's some bug in the importer; Seattle maps didn't get
regenerated last change. Picking up the diffs now.
For the (still disabled) cases of merging short roads, this helps
immensely. It doesn't affect most other maps visibly. Makes a few
already broken things in Krakow and London slightly worse, but don't
care, because they didn't look sane before either.

Two SVGs get duplicated between widgetry and abst assets -- dont_walk

Verified there are no changes when importing the affected cities (except

Woops, and fix updater uploading with the compressed_size_bytes change.
- Tune colors in the experiment
- Regenerate maps again -- I forgot that the parcel data gets joined in
a later importer step.
- Add some of the new maps as levels
degrees to 30 degrees. It works around the issue in #428, but it doesn't
solve the root cause there, so the unit test is also adjusted to provide
a way to solve the harder problem.
Regenerated all maps accordingly. Many traffic signals tended to
improve, with a straight turn marked protected, instead of permitted as
a "right turn."
saves lots of callers from cloning the request and separately plumbing
around the requested start/end distance. Also a step towards exposing
more granular distance crossed in a path for #392.
Still a few more places to simplify, but will do in a separate, smaller
change.
processing code in widgetry doesn't handle paths nested under groups
with transforms. To workaround, preprocess the SVGs:
1) Open in Inkscape
2) Click the problematic group
3) Menu "Path > Object to path"
4) Menu "Extensions > Modify path > Apply transform"
And scale down the two bike sprites
space on maps with "private area around houses".
And a few tweaks to the KML viewer to make it more useful:
- optionally save the clipped file
- click an object to view all attributes in a scrollable popup
The schedule validation changes slightly. No-op trips between the same
origin/destination are now an error and get filtered out.
huge_seattle scenario goes from 129MB to 110MB with the redundant
endpoints removed.

NOW regenerate scenarios. I'm confident this sweeping refactor didn't

has to be tweaked manually, since there's no longer a nice way to spawn
vehicles at a non-border intersection and force them to use a certain

remote trip goes between two locations off-map, specified just by a GPS
coordinate. The trips aren't simulated at all. They were originally
added to support Orestis's pandemic model, to handle transmission
off-map in shared buildings. This work has died off, there are no other
anticipated use cases for remote trips, and they complicate bigger
refactorings. #258
This also has the nice side effect of substantially reducing scenario
size -- huge_seattle from 177MB to 147MB. That unused metadata was
expensive!

This is a pretty huge change, but the compiler gives reasonable
confidence it's correct. More bugs are likely to crop up in the next
step, when filenames start being namespaced by the city too.
Uploading files individually to Dropbox is flaky, and the unique URL per

I could continue to skip the warning for more situations, but I think
this sort of data quality check could be done better in the OSM viewer.

Sanity checked at Rainier / S Massachusetts, and 23rd / S Massachusetts.
- Temporarily workaround snap_cycleways crash in Xi'an
- Fix interpretation of blank turn restrictions. https://www.openstreetmap.org/way/739621435 was missing a right turn, which was causing vehicles to do this crazy loop to go from Madison EB to Lake Wash SB.
- Ignore turn restrictions when they don't match the number of lanes. https://www.openstreetmap.org/way/428090702 and similar need some updating.
Regenerate all data, but give up on lakeslice running fully. Going to
sacrifice that one for a bit to get new roads imported.
We were drawing "pop-up" style buttons in several places, using
copy/pasted logic - which was simple enough when using a unicode glyph.
But we want to use a different glyph which isn't in our font. Further,
using an svg like this gives us finer grained control around the layout
around the button "handle" than we could get with just space characters.

about. This fixes a weird incoming border in SLU into an unreachable

problems to normal or oneshot maps, with or without explicit clips.

- 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

anything.
