OpenTrace ML: Help Build Privacy-Aware Road Intelligence in Python

Vraj Patel — Thu, 03 Sep 2026 09:06:09 +0000

OpenTrace ML is an Apache-2.0 Python library for experimenting with road intelligence using computer-vision detections, incremental traffic forecasts, GPS traces, and map signals.

The current Stage 4 pre-alpha version can:

parse RDD2022-style road-damage annotations;
adapt model-independent callable detectors;
calculate detection and forecasting metrics;
learn traffic patterns incrementally;
place detections on GPS traces and export GeoJSON;
prepare consented GPX traces with pseudonymous trip IDs;
validate map-matching results without depending on one routing engine;
calculate transparent route-reliability scores.

git clone https://github.com/vrajpatell/opentrace-ml.git
cd opentrace-ml
python -m venv .venv
source .venv/bin/activate
pip install -e '.[dev]'

  python examples/map_match_fixture.py

python -m pytest -q

These examples use tiny original fixtures and require no external dataset download or routing service.

Where contributors can help

Our highest-priority task is creating a tiny offline OpenStreetMap integration fixture.

Other open tasks cover:

per-class road-damage metrics;
an optional MMDetection/RTMDet adapter;
GPS recording-gap handling;
privacy-preserving aggregation thresholds;
pseudonym-key rotation and retention guidance.

Contributions involving Python, machine learning, computer vision, GIS, routing, privacy, testing, and documentation are welcome.
