cda586dfc9 Cleanup by moving some methods to belong to MapName. #326 2020-11-05 14:18:13 -08:00
Dustin Carlino
4f2cda8d53 Reorganize data/system/ files by city! The only interesting change is 
abstutil::path_all_maps becoming abstutil::list_all_maps. #326

e17273dc31 Expose distance crossed per agent in the API. 2020-11-05 12:19:58 -08:00

67530bec07 Future-proof file organization by changing map_name from a string to a 
struct. Whatever choices we make next about naming cities hierarchially
or not can be managed in just one place. #326

This is a pretty huge change, but the compiler gives reasonable
confidence it's correct. More bugs are likely to crop up in the next
step, when filenames start being namespaced by the city too.

1707b6fe37 Consolidate some PolyLine geometry code, and refactor some geom->geojson 
mappings
 2020-10-29 12:23:39 -07:00
Dustin Carlino
f187cf4bd8 Add an API call to export intersection geometry to geojson, for experimental streetmix3d integration. 
To get an example:
> cargo run --bin headless -- --port=1234
> curl http://localhost:1234/map/get-intersection-geometry?id=291

3ed7e73aa8 Use a u64 RNG seed, not a u8 2020-10-29 09:25:07 -07:00

a579cb4f74 Add a sanity check to catch live map edit bugs faster. Deleted turns 
aren't getting cleaned up properly.

Also fix broken headless build, woops.

c435d3fce2 Consolidate two scenario modifiers, allowing all walking trips to be cancelled, for #368 2020-10-19 18:03:17 -05:00
Dustin Carlino
422882c03b Ditch cpuprofiler in favor of cargo flamegraph. Add a tool that just 
runs a scenario headlessly, since that's easier than sending a few curl
commands to the API. #368
 2020-10-15 17:12:38 -05:00
Dustin Carlino
b3525f95a2 Enable profiling in the headless server. #368 
(Although actually, I'm liking cargo flamegraph better than cpuprofiler.
Might rip out the support for cpuprofiler.)

traffic demand data.

c9fbf67989 Rearrange headless API to explicitly apply edits at the same time as

Rename Phase -> Stage, to be more in line with standard traffic signal (#302) 
controller terminology. Part of #197.

Holding off on touching PhaseType and all of the serialized
seattle_traffic_signals format, since this will all change in Kyle's PR
anyway.

11832aa606 Record throughput through a traffic signal by direction, expose through 
the API (#245), and beef up the Python example.

Impact to prebaked file size is tiny -- for lakeslice, the original
intersection_thruput is 2MB and the new traffic_signal_thruput is 435KB.
