90e2e4f249 Grab fresh Seattle OSM to fix the entrance to Broadmoor for #537. Also
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

e071b39553 Add a button to save scenarios to a file if they're generated. This is useful for avoiding the performance hit of regenerating them again. 2021-03-17 10:02:52 -07:00

95b1d884cf Rename Map::new to be more clear that it should only be used in non-UI
tools. There's one place in the UI that doesn't work on the web!

f254bb53cc Measure intersection delay more intuitively. #549
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.

bf8f51ae05 Consistently count hours for a time. There was some disagreement between
recorded analytics and code that later summed things up, making the
relative throughput layer more confusing than it is already. #85

957d08e8b9 Add tooltips to the relative throughput layer, to get exact before/after counts of the data being displayed. #85
(The before counts are still bucketed on the hour mark)

d13478f355 Make Poundbury run more smoothly, and prebake sim data for all
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.

7170efbdba Improve some gridlock cases near roundabouts particularly. #114, #75
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.

17e2f485b4 Add support for highlighting certain people in the simulation. For now,
mark random people as highlighted when background traffic is active for
actdev. #539

This changes the unzoomed rendering to "fade out" unhighlighted people.
Next up, similar change for zoomed, info panels, and trip tables.

A few traffic signal cleanups: (#512)
- Stop alerting when slow pedestrians can't make it through the minimum
  crosswalk time
- Simpler iteration style in lagging_green.rs
- Totally delete the old brute force signal config code; it never worked
  well, and the improved heuristics eliminate the need for it anyway
- Make a Duration::max function and use it in one case

Lagging green (#510)
Add a template for lagging green

Lagging green is variable. Crosswalks are also variable.
convert_to_ped_scramble() is refactored to allow a call that doesn't promote yield to protected; as this could unintentionally extend a variable phase.

Skip all-walk if no demand (#442)
* Skip all-walk if no demand

If you create an all-walk stage and make it adaptive, if there is no demand it will be skipped. Fixed crosswalks are never skipped, as they may be necessary for queue management.

e55079fcab When we nuke cars while live editing, sometimes we need to clean up
reserved parking spots to avoid a leak and a later crash. #312

With this change, both montlake and lakeslice survive a full day of
traffic seitan making nefarious live edits...

c9c6f240ae Remove timer.{note, warn, error} in favor of the log crate. #262
Originally, the intention of the deleted calls was to not interrupt
Timer progress bars with warnings. But the output of things like the
importer is impossible to read anyway. Strongly considering explicitly
sending logs and timing info to separate places and using something like
multitail for live progress.

Unplumb timer from LOADS of places that just needed it for logging.

bccf389058 Don't attempt to wake up follower agents behind agents deleted during

this was crashing. #312

traffic_seitan once again makes it through the full montlake scenario,
and crashes on lakeslice around 3am.

4c6d7af76d Bring in linear pedestrian highways as cycleways+shoulders. #458
Also give living_streets in Krakow shoulders, so foot routing works
better there.

Now regenerate everything. Actually messes up routing for Trumpington;
71 cancelled trips up to 101. And have to intervene to keep lakeslice
not gridlocking, as usual.

0a353f67f8 When importing external scenario data for cyipt/actdev#32, snap border endpoints based on the allowed modes of each border. Without this, some driving trips snap to the cycleway next to a road.

48a60c965b For extremely short roads (under 2 meters after calculating intersection
geometry), don't generate crosswalks or stop signs. In reality, these
usually represent the middle of a complicatd intersection. Ideally these
cases would be merged into a single intersection, but before that's
feasible, at least improve some of the inferred things nearby. #457

0eda6307cd Defer creating TripSpec until the trip actually starts. #258
This speeds up scenario instantiation (because picking a bus to use can
be spread out over time) and is a step towards simplifying the spawning
code. Starting downtown goes from 12.8s to 2.2s.

All vehicles spawning at a border now regress to using the 1st valid
lane, instead of random. Now that the choice is made when the trip
starts, this could later be improved to pick the least loaded lane.

Now regenerate everything.
