What traffic is

traffic is a free Python library for analyzing air-traffic data, flight trajectories, and airspaces. It reads open ADS-B sources such as OpenSky Network data and EUROCONTROL DDR files, with support for additional sources. Flight and Traffic structures wrap pandas DataFrames, while airspaces use Shapely geometries. Documented analysis includes detecting flight phases, landings, holding patterns, and pushbacks, plus trajectory resampling and fuel or emissions estimation. Matplotlib supports static charts; Altair and ipyleaflet provide dynamic Jupyter views. Results can be exported for CesiumJS and Google Earth. Integrations include OpenSky live and historical data, EUROCONTROL files, OpenStreetMap airport information, and OpenAP estimates. Installation through conda-forge is documented for Python 3.9 or newer. The library runs on Linux, macOS, and Windows and can be used through APIs or self-hosting under an MIT license.

Who it suits

traffic suits Python users analyzing flight paths, airspaces, navigation events, or aviation emissions. It also fits teams needing Jupyter visualization, export formats, or self-hosted processing.

What it does well

  • Free MIT-licensed library
  • Trajectory detection tools
  • Static and dynamic visualizations
  • CesiumJS and Google Earth exports
  • OpenSky and EUROCONTROL access

What to know first

  • OpenSky historical data needs credentials
  • Coverage or storage limits may return empty results
  • EUROCONTROL B2B access needs a certificate
  • Python 3.9+ documented for conda installation

Verdict

traffic provides aviation data structures, trajectory analysis, visualization, and export capabilities for Python workflows. Access requirements from OpenSky and EUROCONTROL may affect which datasets you can use.
