There are some caveats with the implementation commented inside.
Verified manually in Montlake -- down to just 122 cancelled turns!
Still not regenerating...
movements, make sure that a vehicle can access BOTH the source and
destination lane of a turn. #555
Without this fix, a turn from a bus lane to a driving lane is allowed
for cars at the pathfinding v2 level, but then it fails when converting
into v1 lanes.
(Next step: actually allow this for combination bus/turn lanes)
Not regenerating data yet
https://www.openstreetmap.org/changeset/105381427 mapping a turn lane is
the fix, preventing crazy U-turns using the service road. Not sure how I
missed that lane when looking here before. I made the edit to .osm
locally instead of grabbing fresh data for all of Seattle.
for people that leave one border, then re-enter a different one. #664
Alternative considered: insert a dummy remote trip between the two
borders. We used to do something like this at non-trivial code
complexity expense and having to explain the trip in the UI.
Regenerated all scenarios and prebaked data.
- Modest file size increase, as expected. Montlake scenario goes from
1.3MB to 1.5, downtown from 37MB to 43MB, all Seattle scenarios from
280MB to 327MB
- Eyeballed a few of the previously broken trips; they work now!
- Montlake goes from 3127 cancelled trips to just 302!
- No new gridlock, except in Rainier Valley -- disabling that for now
- I discovered missing validation in Poundbury for no-op trips between
the same building. I'll filter those out and restore prebaked results
there in a followup.
way, we have trip stats for people starting near the end of the day, and
we stop incorrectly showing failed trips when comparing.
Prebaked data: no change in size (245MB)
Montlake: 3135 "cancelled" trips -> 3127
Lakeslice: 6766 "cancelled" trips -> 6647
And fix an absolutely infurriatingly bad typo from the previous commit.
Now both the multiple_left_turn_lanes and divided_highway_split test
maps look great!
* Update dependencies
* Use github for polylabel, to make all dependencies use geo 0.18, not a mix of 0.18 and 0.17
* Downgrade lyon to avoid a crash

edits to a road before entering the zone editor. Users can use edit
mode's undo if they made a mistake. It's more fluid than prompting.
Use the same auto-compress flow to allow switching to different roads,
without leaving the road editor
selector into debug mode. #597
Previously, it was used both to search/replace lane types and to
select roads, then dump them in various formats. Just preserve the
latter behavior.
- Disable the 'edit multiple' button if the current road hasn't been
changed yet
- Start with no other roads selected
- Add a "select all" and "select none" button
- Show the count of segments in the panel
- fix self-destruct command
- ship a GDAL-enabled importer and rebuild everything for Seattle, like
the normal local process
I'm pretty sure the full process should succeed now. Next step is
figuring out a process for finalizing the changed output files in S3.
- Amp up number of workers (about 100 cities, so 10/worker now)
- Use an SSD, since especially the setup and upload steps are extremely
IO bound
- Split the script into pieces that can be easily disabled to iterate
faster
- Use the bulk API to create instances
- Make the overall start_batch_import.sh a bit quieter
- Make successful VMs self-destruct so it's easier to track which're
done
- Setup Docker on the VMs, so elevation data works
