Traditional automated crash analysis systems heavily rely on static statistical models and historical data, requiring significant manual interpretation and lacking real-time predictive capabilities. This research presents an innovative approach to traffic safety analysis through the integration of ensemble learning methods and multi-modal data fusion for real-time crash risk assessment and prediction. Our primary contribution lies in developing a hierarchical severity classification system that combines spatial-temporal crash patterns with environmental conditions, achieving significant improvements over traditional statistical approaches. The system demonstrates a Mean Average Precision (mAP) of 0.893, representing a 15% improvement over current state-of-the-art methods (baseline mAP: 0.776). We introduce a novel feature engineering technique that integrates crash location data with incident reports and weather conditions, achieving 92.4% accuracy in risk prediction and 89.7% precision in hotspot identification. Through extensive validation using 500,000 initial crash records filtered to 59,496 high-quality samples, our solution shows marked improvements in both prediction accuracy and computational efficiency. Key innovations include a robust data cleaning pipeline, adaptive feature generation, and a scalable real-time prediction system capable of handling peak loads of 1,000 concurrent requests while maintaining sub-100ms response times.
