First time doing this in about a week. Trevor's new amenities should
show up, and lane widths are now adjusted. Haven't yet regenerated
the screenshot diff, because it's segfaulting (!!) for some reason. And
Seattle's popdat.bin and ALL of the scenarios are temporarily hosed. So
if you pull from git head and run the updater, expect some weirdness.
Working on fixing this.
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.
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
leading to the intersection.
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!
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.
