Avinor Airport Concurrency Prediction
Data Scientist & ML Engineer
Comprehensive airport concurrency forecasting system. Analyzed 465k+ training records spanning 7 airport groups, engineered lagged traffic features, validated with temporal splits, and deployed a calibrated ML classifier achieving superior performance across all airport groups.

Avinor needed to forecast when AFIS controllers would handle multiple simultaneous aircraft communications across seven Norwegian airport groups, enabling proactive resource planning and safety protocols.
Approach
Built a two-tier prediction pipeline: baseline rate tables (group-hour and group-weekday-hour) with hierarchical fallback logic, then trained Logistic Regression and HistGradientBoosting models using engineered features (seasonal flags, planned flights, lagged concurrence) with strict no-leakage validation splits.
Outcome
Delivered a HistGradientBoosting model achieving 0.9731 AUC and 0.0503 Brier score, outperforming baselines and providing per-airport predictions for October 2025 scheduling.
Highlights
- HistGradientBoosting: AUC=0.9731, Brier=0.0503
- Per-airport AUC ranging 0.94-0.99 (groups A-G)
- Hierarchical baseline with smart fallback logic
- Strict temporal split preventing data leakage
