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!
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.
in the interior of a big intersection. #255, #114
- No sidewalks or parking on it
- Automatically try to merge it
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.
for all the custom extra import data. #326
Verified there are no changes when importing the affected cities (except
for renaming the original OSM input file for Leeds to match the
geofabrik source)
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."
