Autoware CARLA Scenario

A CARLA scenario testing framework for Autoware. Drives an Autoware ego vehicle through configurable scenarios in the CARLA simulator, evaluates pass/fail conditions tick-by-tick, and produces JSON results plus a trajectory log of the run.

It is typically run against OpenDRIVE maps produced by the convert CLI of autoware_lanelet2_to_opendrive, but does not depend on it: the Lanelet2 and OpenDRIVE maps are loaded as two independent coordinate systems, related only through CARLA world coordinates.

Features

Automated scenario execution against CARLA UE5 (0.10.0 and ue5-dev), through the statically typed typesafe_carla client.
Hydra-composed configurations for map, server, ego, entities, and scenario.
Glob-pattern batch execution of multiple scenarios in a single CARLA session.
Condition system: timing, collisions, traffic signals, speed/standstill, lane/area position, waypoint crossing, plus logical (And/Or/Not), latching (Sticky), and persistent combinators.
Action system: turns, lane changes, traffic-light state, on-demand camera attachment.
Pluggable traffic backends: CARLA's TrafficManager by default, traffic=none for an empty road, or a traffic simulator of your own through an entry point.
Coordinate transforms between Lanelet2, OpenDRIVE, and CARLA world frames.
Hydra lanelet_constraint sweeper plugin for parametric map-driven sweeps (resolvable without CARLA).
FastAPI + Uvicorn web viewer for browsing results and triggering runs.
A trajectory log of every run (actors, lights, map, the ego's plan, conditions, verdict; JSON Schema in the package), which the autoware_carla_scenario_rerun package (convert / convert_dir) turns into a Rerun recording to see the run, beside CARLA's native recording.
scenario-setup downloads CARLA's nightly build, which the runner then launches by itself.
pytest integration via CarlaScenarioFixture (auto-skips when there is no CARLA to launch).

Installation

Python 3.10 to 3.14 (>=3.10,<3.15, the interpreters CI tests), Linux x86_64 or aarch64 (CARLA's server itself is x86_64 only; see installation). Install via the workspace root:

# From the repository root
uv sync --dev

The CARLA client is typesafe_carla (typesafe-carla on PyPI), a plain dependency — no extra to request — imported as import typesafe_carla.carla as carla. Its PyPI wheel carries the CPython package prebuilt, so the sync above compiles nothing (installation has the cases that build it instead). The official carla wheels, and CARLA 0.9.16 (UE4), are no longer supported. CARLA's simulator binary itself is downloaded by uv run scenario-setup (the nightly build, into ~/.autoware_carla_scenario/bin/carla); see the quick start.

Quick usage

The package provides these CLI entry points:

Command	Framework	Purpose
`scenario`	Hydra	Run autonomous-driving scenario tests in CARLA
`scenario-setup`	argparse	Download CARLA (the nightly build) for `scenario` to launch
`detect-no-3d-model`	argparse	Detect lanelets without a matching 3D ground model in CARLA
`viewer`	FastAPI + Uvicorn	Web UI for browsing and monitoring scenario results

Run a scenario

Uses a CARLA server already listening on the configured host/port, or launches one: CARLA_EXECUTABLE, else the one scenario-setup installed.

# Single scenario
uv run scenario scenario=intersection_passing/straight

# Batch run via glob pattern (sequential, single CARLA session)
uv run scenario scenario='intersection_passing/*'

# Other built-in scenarios
uv run scenario scenario=lane_change/left
uv run scenario scenario=temporary_stop/temporary_stop
uv run scenario scenario=traffic_light_compliance/traffic_light_compliance

Results (JSON and the trajectory log) are written under the configured output directory and can be inspected interactively via:

uv run viewer

Detect missing 3D models

For diagnosing lanelets that do not project onto a CARLA ground mesh:

uv run detect-no-3d-model --map /path/to/map.xodr
