No behavioral change here; this is a trivial transformation. If a
directed road has any walkable lane, then there's exactly 1 of them. I
verified by manually checking paths and also seeing prebaked results
having zero diff.
always tiny; Dijkstra's is fine. It costs a bit of file size to store
it. The huge leeds map goes from 160MB to 157MB -- not crazy savings,
but something.
Also fix a slight bug with 92d3a890ea that
caused some pedestrians to uselessly visit a bus stop node while
routing. (southbank crashes a few hours in otherwise)
This is simpler to reason about, allows the penalty for entering a zone
or taking an unprotected turn to be expressed in terms of a time
penalty, and is a step towards adjusting bike/foot routing for elevation
data.
When we later add things like "safety/quietness" for cycling, maybe we
can switch to using a (time, quietness) tuple, and transform into a
single number with a linear combination parameterized by that agent's
preference for time/safety. This change is compatible with that future
idea.
There are behavior changes here, particularly for zones and unprotected
turns. No new maps start gridlocking, and in fact, Rainier starts
working again.
"rise / run" calculation used the trimmed road center-lines, which don't
match up with the elevation at each original intersection point.
Also handle infinity in the output and reduce the resolution of the
query from every 1m to every 5m.
Regenerate all maps due to the map format change. Try bringing in
elevation data for all of Seattle using the LIDAR source, since
the data quality assessed in eldang/elevation_lookups#12 seems to be
similar, and LIDAR is way faster than contours.
Regenerate all maps. Gridlock-wise, Rainier and Poundbury broke, but
Wallingford started working again. Acceptable cost for a change this
useful; I'll work on fixing those maps later.
stop importing golf cart paths, even though they would be kind of
interesting to use for this proposal...
Interventions needed to keep lakeslice running, of course
Instead of just picking the intersectin closest to the origin or
destination, calculate the full path length, and take the one with the
shortest distance. This fixes some of the weird problems routing around
Broadmoor. Regenerate all prebaked data.
Also fix the original request for paths involving zones, so tracing it
later works.
So far, just call it for Seattle maps. Store the data sources in S3.
Note this'll only run on my machine right now, unless you also build the
Docker image locally. Failures in elevation should be skipped for now.
- Increase day mode panel opacity to 95% to help text legibility
- Combine the time/speed panels, and remove the sunrise/sunset icons
- 4 mode colors matching actdev, also changing night mode residential

Before: time starts when the vehicle reaches the front of the queue and
first requests their turn
After: time starts when the vehicle first becomes blocked on the queue

Regenerate prebaked data.
wind up looping back on themselves in a nonsensical way, causing
vehicles to visually glitch when moving through.
This was started in 081819d86b, but it
used to gridlock 2 maps. All the recent roundabout fixes seems to have
resolved those! And adjusting offstreet parking for two maps.
But wallingford does regress; plunging forward for now.
scenarios, so we can run A/B tests with map edits. cyipt/actdev#114
To fix it up, I hand-timed
https://www.openstreetmap.org/node/2124133019, which could have smarter
heuristics as a button-operated half-signal in the future. And allowed
blocking-the-box on some small intersections near that area.
1) If a car is blocked by a conflicting turn and is part of a cycle,
wake up the car blocking it. In some cases, this wakes it up faster
and unsticks things. Otherwise, it just wastes a little bit of time.
2) If a car is part of a cycle, allow blocking-the-box.
3) Continue sorting people at a stop sign by the time they've been
waiting. But for cars "overflowing" their current lane, move them to
the front of this ordering. It unsticks one particular situation.
4) Fix wakeup_waiting entirely. Before, it was waking up protected turns
before permitted, but otherwise the ordering was arbitrary. Now actually
respect stop sign ordering. I expect this to improve many other
situations than the one I was checking.
This was all motivated by one particular roundabout in Poundbury. It
doesn't solve gridlock there, but it gets past a major blockage.
If a study area exists for the map, make a copy of the base/active
scenarios with the background traffic mixed in. Also remove people
living in the site, since they're redundant.
Ran it like this: for city in `ls data/system/gb/`; do ./import.sh
--scenario --city=gb/$city || break; done
attention to which intersection is being destroyed. Fixes#527 --
montlake and phinney both look correct now.
Regenerating everything. Actually, Phinney now runs, so adding a 4th
prebaked map!!! But Rainier regressed -- there's an issue with the
signal heuristics that's now a problem; I'll fix later.
I experimented on the Rainier Valley map, which recently started
gridlocking due to too many cars doing this, to tune the value. Got it
running again! The two other maps keep running, with some trips on
average getting a little slower.
Added an extra step to classify service roads as running through a
parking lot, to prevent them from being treated as regular roads.
Had to fix up a few prebaked traffic signals. lakeslice falls back into
gridlock; will fix separately -- too much effort behind this change to
stop.
be more careful with nodes representing uber-turns. Even if that vehicle
type doesn't use an uber-turn, we still need to force the nodes to exist
and match up between input graphs.
Although this really only fixes gb/charleville_mezieres/secteur4, it
potentially affects all maps, because the node map changes. So
regenerate everything...
City names are now disambiguated by a two-letter country code. This
commit handles almost everything needed to make this transition. Main
next steps are fixing up map edits automatically and making the city
picker UI understand the extra level of hierarchy.
A little bit of fallout: lakeslice gridlocks again; this regression is
actually from the recent traffic signal changes, but I'm just now
regenerating everything. Will fix soon.
use the site name as the city, instead of picking the "closest" major
city. This is introducing too much friction in automation.
cyipt/actdev#65
There will be a few awkward results -- cambridge gets renamed, and lcid
gets disassociated from leeds. Worth it for now.
source to augment the ones in OSM. For
https://github.com/cyipt/actdev/issues/53 -- sometimes the buildings
just haven't been mapped in OSM yet, other times the buildings are part
of a future development site. In either case, we can procedurally
generate some houses, so this is a way to include them in the map.
Start doing this for Chapelford. But first, adjust the generated house
sizes -- they were WAY too tiny.
Also prep for [rebuild] [release]
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`
* CR: remove outdated doc
* import order
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.

actually read from the filesystem. #253
Two SVGs get duplicated between widgetry and abst assets -- dont_walk

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."
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.
TripEndpoints from TripLegs. #258
NOW regenerate scenarios. I'm confident this sweeping refactor didn't
break behavior, because prebaked data didn't budge. huge_seattle
scenario went from 147MB to 129MB. Not bad!
in favor of Option<TripEndpoint>. The bike/car contention tutorial stage
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
DirectedRoad. #258
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!
