Optimize scheduler

11

Profiling reveals https://github.com/dabreegster/abstreet/blob/master/sim/src/scheduler.rs as a hot spot, which makes sense. Anybody have ideas to speed it up? It's a priority queue with updateable priorities. There are lots of alternatives to...

Improve discrete event performance during gridlock

15

Follow https://dabreegster.github.io/abstreet/trafficsim/gridlock.html#strategy-for-resolving until the full day can complete at all. Currently: ``` cargo run --release --bin headless -- --disable_turn_conflicts --infinite_parking --disable_block_the_box --port=1234 --alerts=silence curl http://localhost:1234/sim/load -d '{ "scenario": "data/system/scenarios/downtown/weekday.bin", "modifiers":...

Use case: In https://www.reddit.com/r/Seattle/comments/nlprut/biking_hills_map/, it would've been nice to toss `&layer=steep_streets` in the URL. Any other shortcuts missing and likely useful? Maybe info panels too -- `&info=b47`, with the value...

@kfarr and I chatted a bit about this. Here's an end-user workflow: 1) Someone wants to visualize the current lane configuration of any street in the world 2) Through the...

Support Response chunk in wasm

1

`Response` on native has a [chunk method](https://docs.rs/reqwest/0.11.4/reqwest/struct.Response.html#method.chunk), which allows some kind of progress bar, [like this](https://github.com/a-b-street/abstreet/blob/01fbfd37ae7864abd827ea9f26bc2d2a6258c630/abstio/src/download.rs#L32). The [wasm Response](https://github.com/seanmonstar/reqwest/blob/master/src/wasm/response.rs) doesn't have anything similar. Any plans to add it? I've come...

Integration with A/B Street?

1

Hi, I stumbled across this repository looking for open data about traffic signal timing. I think the [GMNS spec](https://github.com/zephyr-data-specs/GMNS/blob/master/Specification/Signals.md) is the first specification I've found. I'm working on a traffic...

Both proposal save files are way too brittle

A/B Street has map edits and the LTN tool has its own format for boundaries and filters. Both files currently reference OSM way and node IDs to refer to road...
