Dustin Carlino 0133685eb7 converted the import.sh shell script into Rust. towards #27 
as part of this, wound up grabbing fresh OSM and GTFS. but actually cant
reimport OSM right now, because fixes reference old OSM IDs and things
break. so sticking with old OSM, but new GTFS. urgh.

Importing a new city into A/B Street

My current priority is to make Seattle work very well, but if you want to try out A/B Street in another place, you can follow this guide. Add to this issue if you find a new problem.

First obtain a .osm with your desired area. You can use a tool like Osmosis to clip a specific area from a large file. Put the .osm in data/input/osm.

Then you'll run some tools to import the map. Make sure you can compile everything from source.

cd convert_osm
cargo run --release -- \
  --osm=../data/input/osm/your_city.osm \
  --drive_on_right=true|false \
  --output=../data/input/raw_maps/your_city.bin
cd ../precompute
cargo run --release -- ../data/input/raw_maps/your_city.bin

You should now be able to load the map using the option from the main game menu, or by running cd game; cargo run --release ../data/system/maps/your_city.bin.

Future work

There are Seattleisms baked into the code. (As of March 2020, this is out of date; I'm actively fixing most of these.)

  • import.sh should be generalized.
  • The driving side of the road is hard-coded to the right. Look for "driving on the left" in map_model/src/make/half_map.rs.
  • On-street parking is mostly not mapped in Seattle. Ideally you should fill out https://wiki.openstreetmap.org/wiki/Key🅿️lane for your city. I'm inferring these tags for most roads based on a King County GIS-specific dataset.
  • Demand data to generate a realistic set of trips comes from an agency specific to the Puget Sound, but again, importing this from other sources isn't hard.
