OSM and other raw input into and store, before later converting to a
Map.
Why?
- build-time performance: while iterating on geometry problems, map_editor in release mode took 33s to build before, 11s now that the crate is split
- better layering: operations on a RawMap are becoming increasingly distinct from later transformations on the bigger map model
- this helps tease apart the dependencies of the intersection polygon algorithm for #846
- this will make it simpler to cutover to osm2lanes for https://github.com/a-b-street/osm2lanes/issues/71
There's further reorganization in raw_map and map_model that'll follow,
but the main work is done here.
dramatically improve time to import and edit maps.
The fix helps all maps that use extremely high edge weights to prevent
people from cutting through private roads. There may be a more robust
fast_paths fix later, but I want to reap the benefits for tomorrow's
release.
The dramatic numbers:
- importing huge_seattle: 893s down to 108s
- editing huge_seattle: 102s down to 19s
Query speeds didn't appear to substantially change.
"engine" that just operates on raw usize IDs. Embed that enum in each of
the particular pathfinders. This way, we don't have to keep duplicating
logic to delegate requests, handle one-step edge cases, etc. And it also
sets us up to more easily try out other CH implementations like osm_ch,
without having to move around tons of code.
Still use fast_path's InputGraph as the "universal" format, for now.
This is a huge change... got map_model compiling at least. Some stubbed
out stuff.
- Adding an internal alt_start to PathRequest
- Using it for contraction hierarchy queries only (the Dijkstra
implementation now diverges!)
- Figuring out which start position was used
TODO:
- Fix the unparking position
- Make sure the simulation inserts static blockages
- Carefully check the same start/end road case
- Evaluate impact on gridlock / cancelled trips
* Add craft and office to import and add/reorg AmenityType
* Remove bike rental/parking and rename BikeShop to Bike
* add in leisure and tourism tags, add more categories to AmenityType and remove lesser used tags
* add dependency on strum and strum_macros and removed some manual code for text display of Enum and Enum into string
* include lock file, fix color of buildings for amenity layer, fix formatting and use orders
widgetry, geom, and abstutil may wind up on crates.io in some form to
let other projects use widgetry. abstio has A/B Street-specific tricks
for reading data on native/web. Note widgetry still depends on abstio,
will figure out how to clean that up next.
Originally it was split out to organize a separate volunteer mapping
effort, but that never took off, and it's unlikely to happen. When we
have to occasionally update the prebaked signal data for some
intersections, it's unnecessary friction to update the other repo.
* WIP set up plumbing for calculating building info in the Raw layer and using it later for #154
* WIP playing with processing modifications
* experiment with some possibilities for tag processing
* fix an embarassing typo
* enable busses in work-home traffic
* refactor, add multiuse
* seed more parking in Kraków
* parse integers properly - thanks for a help!
* rebalance generated trips
* add hack providing some background traffic
more realistic traffic
even mess realistic people
* attempt to further reduce parking deficit
* add TODO
