scenario-characterization 0.3.7

Automated Scenario Characterization Toolkit.

ScenarioCharacterization

Note: This project is a work in progress.

A generalizable, automated scenario characterization framework for trajectory datasets. This project is primarily a re-implementation of the scenario characterization approach introduced in SafeShift, as part of an internship project at StackAV.

Categorical Scores	Animated Scenarios	Static Scenarios
Result from our categorical profiler. Agents are visualized from dark green (low crit.) to dark red (high crit.) based on their criticality w.r.t. the ego-agent (blue).	Result from our animated visualizer, Shows agents by color vehicle (gray), pedestrian (magenta), cyclist (green) and ego (blue), and the scenario's elapsed time throughout the episode.	Result from our static scenario visualizer. Episode's time is shown by increasing trajectory opacity over time.

Repository: github.com/navarrs/ScenarioCharacterization

This repository currently uses:

• uv as the package manager.
• Hydra for hierarchical configuration management.
• Pydantic for input/output data validation.

Installation

Install the package

uv pip install scenario-characterization

Install the package in editable mode

Clone the repository and install the package in editable mode:

git clone [e-mail]:navarrs/ScenarioCharacterization.git
cd ScenarioCharacterization
uv run pip install -e .

To install with Waymo dependencies (required for running the example), use:

uv run pip install -e ".[waymo]"

If installing with dev, run

uv run pip install -e. ".[dev]"
uv run pre-commit install

Documentation
