simple-scenario

Quickly generate prototype test scenarios for automated driving.

Examples

Generate all kinds of highway test scenarios from simple config files (see .json files in demo/examples/).

:bulb: To recreate these gifs use: demo/examples/generate_gifs.py.

Deceleration test scenario (example_scenario1.json):

Cut-in test scenario (example_scenario2.json):

Deceleration test scenario with surrounding traffic (example_scenario3.json):

Cut-in test scenario with surrounding traffic (example_scenario4.json):

:bulb: For more examples, see tutorials/.

Install

pip install simple-scenario

Use

simple-scenario offers a rich python API and a basic CLI for test scenario generation.

Python API

The python API supports various ways of generating and interacting with test scenarios.

Please conduct the tutorials/A_01_getting_started.ipynb to learn about the basic usage of simple-scenario.

Please find more in-depth examples in the test/ folder (E.g., test/test_scenario.py shows which input formats can be used).

:bulb: Have a look at the Dev section of this readme to find out how to setup the project and run the tutorial notebooks and tests.

CLI

The CLI supports generating a set of

• an OpenSCENARIO (.xosc)
• and an OpenDRIVE (.xodr) file

for a given simple-scenario config file (.json) through the following command

simple-scenario create demo/cutout_example.json

Extras

commonroad-extra

:warning: Needs python version 3.8

pip install simple-scenario[commonroad]

Enables advanced features like feasibility checking of the scenario (powered by the CommonRoad Drivability Checker) and exporting the scenario to the CommonRoad (CR) format.

Please conduct the tutorials/B_01_commonroad_extra.ipynb for more details.

lxd-extra

pip install simple-scenario[lxd]

Enables reading leveLXData datasets through lxd-io.

:warning: Currently only the highD dataset is supported

Please conduct the tutorials/C_01_lxd_extra.ipynb for more details.

Dev

To develop simple-scenario, you must first clone the repository.

$ git clone git@github.com:ika-rwth-aachen/simple-scenario.git
$ cd simple-scenario

It is recommended to use uv for package management. If you do not want to use uv, please consult the Without uv section.

With uv

Install requirements with

$ uv sync

To run a script, use

$ uv run /path/to/script.py

or directly use the python interpreter from the .venv folder in e.g. VSCode.

To run the tests, install the dev requirements with

$ uv sync --dev

and run the tests

$ uv run pytest

To run the notebooks in the tutorials/ folder in VSCode, select the .venv's as the kernel (see here for more info).

Without uv

Install the project editable

$ python -m pip install -e .

To run the tests, first install pytest

$ python -m pip install pytest

and run

$ pytest
