87d233299a Use a HashMap instead of a BTreeMap in Scheduler's internals. Doesn't
affect determistic simulation, but yields a crazy speedup. #54

- 8 hours of downtown: 122s to 102s!!!
- prebake: 181s to 160s

491f4bbffe Speed up the simulation by replacing BTreeMaps with a simple Vec lookup. #368
No behavioral changes. Dramatic performance boost:

- 8 hours of downtown: 170s down to 135s
- prebaking: 3m33s down to 3m4s

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

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.)

c0513a3d64 Reduce time to park/unpark offstreet when --infinite_parking is used.
Downtown forms gridock just from everyone pouring into Harborview! The
point of --infinite_parking is to simplify the sim by not modelling the
impact of parking. #368

1906fb0913 Remove the GetDrawAgents indirection. Originally the UI could pull the
set of agents to draw either from the simulation or from this
"time-traveler" plugin, which would let you rewind sim time. That plugin
is long gone, and it never worked well, because much of the UI would use
the GetDrawAgents to select something, then query the live sim for lots
of details anyway. The plugin never served all of those calls, so the
results would be kind of out-of-sync anyway.

There are some parts of the UI that need to temporarily not draw agents.
Use the same suspended_sim trick that edit mode does.

a1c53d5e1c Humble start to adjusting how distances and durations are printed in the UI. #331
Also trimmed out a few old UI settings; they kind of started as
experiments, but now the alternative feels useless to maintain.

df873a5cf9 Add an option to totally disable turn conflicts in the simulation. Can we make progress on large scenarios only with vehicle queueing rules? (Didn't evaluate this yet, don't want to burn through laptop battery currently)
Also fix zooming in on traffic signals crashing with freeform policy

212ad761fd Switch to Box<dyn Error> in abstutil. This makes it easier to have
higher-level APIs return some kind of string error. Pretty much nowhere
do we care about error types.

Delay highlighting (#363)
* Initial storing of intersection delays

* Initial highlighting of delays on route

* Added label of delay

* Info overlay works

* Added supoprt for pedestrian delays (only intersection delay currently)
Bike also works, but is treated as a car, so the avg speed is flagged as very slow (Needs fix)

* Capitalised describe trip phase
Now uses min of (speed limit and vehicle max speed) for the maximum speed check
Added trip blocked time query
Lots of work on tool tips
Icons are broke

* Nearly complete, just fmting and a crash to fix
Color assertion?

* Fixed text font colour crash
Added new custom TextSpan size function

* Cargo +nightly fmt

* Cargo +nightly fmt

* Clion auto import formatting
Doesn't quite match the existing "changes"

* Fixing merge issues

* Fixing icon placement issues

* Requested changes (Part 1)

* Requested changes (Part 2)

2cd59ead37 Remove the special handling for synthetic maps, which were JSON RawMaps
that could directly be loaded. The few examples have been long broken
and unused. They complicate map loading, because they have a weird path.

ffdedcb0a7 When multiple source lanes can turn left* to multiple destination lanes,
only allow the leftmost source lane to turn to any destination lane. As
a future improvment, need to handle multiple explicitly tagged left turn
lanes, but this gets closer to reality, particularly helping some crazy
maneuvers along Mercer in downtown.

*or right

Also had to update lanes along Madison and fiddle a bit to keep
lakeslice running. Spotted some major traffic signal bottlenecks due to
stage generation falling back, will iterate on that separately.

fd460a2f43 Fix blackholed buildings with --infinite_parking. Before, they were just
skipped outright. Now they redirect to a reasonably close building that
isn't blackholed. #329

(For context, https://dabreegster.github.io/abstreet/map/index.html#connectivity
explains "blackhole")

I'm increasingly convinced I made the wrong decision to split the
normal/infinite parking implementation. It's low-priority, but I'll try
consolidating them later.

2c63a485cc Undo some uses of impl trait. Originally added for performance in a big
refactor, they complicate the function signatures significantly and have
no observable perf impact, since all of the methods just happen in map

Add a layer to color unzoomed agents based on their current delay, to help debug gridlock. Something like this used to exist as a first-class way to change unzoomed color schemes, but until we have more ideas about showing agent intent on the minimap, just implementing this as a separate layer.

4a07164394 Add the concept of trip purpose. Seed it from Soundcast data, or assign

Total scenario size from 385MB to 412MB, but that's not so bad, and this
seems worth it.
