Ranking
We will monitor submissions for attempts to learn from or exploit the ranking process. We consider such practices unfair and inconsistent with the purposes and goals of the Data Challenge.
Leaderboard
We will post urgent and important news news here, but we strongly recommend following the updates on the OSN Discord channel, especially #prc-data-competition
If you haven’t joined the OSN Discord server yet, you’ll need to do so first to access the channel.

All paginated submissions can be retrieved via the REST API at the full leaderboard JSON (use the value of nextCursor in the cursor= parameter in the URL query).
Other endpoints are also available; have a look here and use competitionId = bb3693e1-26bc-4a9e-8619-4fe78b4eab0c.
Submission Instructions
Teams will be ranked based on the best Root Mean Square Error (RMSE) achieved across their submissions.
The submitting.parquet file is provided as a template. To make a submission, fill in the TAXITIME_SEC_mvt column with your predicted taxi-out times for the corresponding MVT_ID_mvt values.
Each team must submit its predictions to its own bucket using the following file naming convention:
<team-name>_v<incremental integer>.parquet
For a submission to be valid, each row must match the corresponding MVT_ID_mvt before the ranking script can use the prediction to calculate the RMSE.
The ranking script will issue an error if:
- an
MVT_ID_mvtdoes not match; - any rows are missing; or
- extra rows are included.
There is currently a limit of 5 submissions per day (and a total max of 1GB per bucket.)
You will NOT be able to submit via the webinterface, please use the MinIO CLI as described in the Data section.
Final Submission
Please submit you unique final submission using the following filename:
<team-name>_final.parquet
