# 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](https://github.com/dabreegster/abstreet/issues/27) 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](INSTRUCTIONS.md).
|
|
|
|
```
|
|
cd convert_osm
|
|
cargo run --release -- \
|
|
--osm=../data/input/osm/your_city.osm \
|
|
--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.
|
|
|
|
- `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:parking: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.
