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
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
