The Relevance of Compound Events in Bee Traffic Monitoring
Bees are essential pollinators for agricultural systems, making accurate, automated monitoring of their behavior critical for assessing colony health and ecosystem stability. Recent advances in computer vision and artificial intelligence have enabled large-scale bee traffic monitoring at hive entrances; however, most existing event classification methods focus exclusively on simple entrance and exit events. This simplification overlooks compound movements—such as U-turns and guarding behaviors—that represent a substantial portion of bee activity and can lead to inaccurate trajectory reconstruction and misleading behavioral interpretations. In this work, we systematically analyze existing event classification strategies used in automatic bee traffic monitoring, evaluating their performance on both simple and compound movements. We then propose extended classification methods that explicitly model compound events by incorporating bidirectional movement patterns derived from positional and angular cues. Using a manually annotated dataset of computer-vision-based hive entrance recordings, we compare threshold-based, displacement-based, and angle-based approaches under simple and mixed-event conditions. Our results demonstrate that compound events account for over one-third of all detected movements and that classification methods explicitly designed to handle bidirectional behavior substantially outperform traditional approaches in both accuracy and robustness. In particular, threshold-based bidirectional classification achieves near-perfect performance when full trajectories are available, while displacement-based methods provide a reliable alternative under partial observations. These findings highlight the importance of modeling compound behaviors in automated bee monitoring systems and contribute to more accurate flight reconstruction, behavioral analysis, and AI-driven decision support for precision agriculture and pollinator management.
Executive Impact Summary
This study highlights the critical need for advanced AI in bee traffic monitoring. Traditional methods, focused on simple entrance/exit events, misinterpret over one-third of bee movements, leading to inaccurate behavioral insights. Our new bidirectional classification models achieve over 90% accuracy, significantly improving flight reconstruction and behavioral analysis. This translates to more precise data for precision agriculture and pollinator management, enhancing decision-making for ecosystem health and crop productivity.

Event Classification
Traditional bee traffic monitoring systems primarily focus on simple entrance and exit events, often overlooking complex behaviors like U-turns or guarding. Our research reveals that a significant portion of bee activity—over a third—consists of these 'compound events'. Failing to classify these accurately leads to substantial errors in behavioral analysis and colony health assessment.

of all detected events are compound movements, often misclassified by traditional systems.
Performance of Classification Methods
Our evaluation shows a clear performance gap. Traditional methods, designed for simple movements, fall short when encountering compound events, often classifying them as 'unknown' or misinterpreting them. Our novel bidirectional threshold and displacement methods, specifically designed to model U-turns and complex paths, achieve significantly higher accuracy, demonstrating the value of explicit compound event modeling.

Methodology
The core of automated bee monitoring involves a multi-stage data processing pipeline. It starts with raw sensor data (RFID or computer vision), groups these into 'events' through tracking, classifies these events into specific behaviors, and finally uses this information for higher-level analysis. Our work primarily enhances the 'Event Classification' stage by introducing sophisticated methods for compound movements.

Dataset and Validation
Rigorous evaluation is crucial for validating AI models. We used a large, real-world dataset and advanced computer vision techniques to capture detailed bee movements. Manual annotation of a subset of events provided ground truth, allowing for a precise and objective comparison of different classification algorithms and confirming the real-world applicability of our proposed methods. The study utilized a comprehensive dataset of 289 hours of video recordings from hive entrances, processed using YOLO11x pose detection and AprilTag QR codes for bee identification and orientation. This rich dataset allowed for robust evaluation of classification algorithms against manually annotated ground truth for 1194 events, ensuring high-fidelity assessment of performance in real-world conditions.
Impact & Future Work
Accurate flight assembly is foundational for understanding foraging patterns and colony health. Our enhanced classification of compound events directly translates to a significant improvement in this area. By reducing misclassifications and overlooked movements, we enable a more complete and reliable picture of individual bee activity, which has direct implications for precision agriculture and conservation efforts.
Real-World Application: Enhanced Flight Assembly
By accurately classifying compound events, our bidirectional methods improve the reconstruction of complete foraging flights. For instance, THRS_BIDIRECTIONAL correctly assembled 130 out of 131 true flights with only 1 false negative, demonstrating 99% accuracy. In contrast, traditional methods like ANGLE_SUM had 29 false negatives, missing crucial flight data. This precision is vital for accurately estimating foraging activity and assessing colony health, especially for detecting subtle changes indicative of environmental stressors or disease.
AI-Driven Decision Support
The broader impact of this work extends to critical areas like food security and ecosystem health. Improved bee monitoring, powered by accurate AI, enables proactive management of pollinator populations. This means better-informed decisions for farmers, conservationists, and researchers, leading to more sustainable agricultural practices and healthier ecosystems. The findings from this research are critical for developing more robust AI-driven decision support systems in precision agriculture and pollinator management. By providing more accurate and detailed behavioral analyses, stakeholders can gain deeper insights into colony health, optimize crop pollination strategies, and better respond to environmental changes affecting bee populations, ultimately contributing to food security and ecosystem stability.
