TrajAir
TrajAir is a general-aviation aircraft trajectory dataset collected by CMU's AirLab (Robotics Institute) around the non-towered Pittsburgh-Butler Regional Airport (ICAO: KBTP), a single-runway GA airport ~10 miles north of Pittsburgh, PA. Data was recorded with an on-site ADS-B receiver (1090 MHz / 978 MHz, plus TIS-B for non-equipped aircraft) over 8 months (18 Sept 2020 - 23 Apr 2021), yielding 111 valid days after excluding downtime, repairs, and no-traffic bad-weather days. Each scene contains aircraft trajectories transformed into an airport-centered inertial frame with x,y,z positions (km), aircraft IDs, and frame timestamps interpolated to 1 Hz via cubic interpolation. Weather context (wind direction/velocity, given as wx, wy components in m/s) is added post-hoc from METAR data produced by the KBTP AWOS system. The data is distributed as delimited text files organized into a full 111_days/ folder, four weekly folders (7days1-4), raw CSVs by collection date, and a processed 70/30 train/test split. It was released with the baseline socially-aware prediction method TrajAirNet (ICRA 2022). This is real physical manned-aircraft data, not simulated.
