+**abstr provides an R interface to the [A/B Street](https://github.com/a-b-street/abstreet#ab-street) transport system simulation and network editing software. It provides functions for converting origin-destination data, combined with data on buildings representing origin and destination locations, into `.json` files that can be directly imported into the A/B Street city simulation.**
 
 See the formats page in the [A/B Street documentation](https://a-b-street.github.io/docs/tech/dev/formats/scenarios.html) for details of the schema that the package outputs.
