Abstract:Intersections are critical areas where a substantial number of traffic accidents occur. Detecting and analyzing near-miss events is key to signaling a high risk of accidents early and taking appropriate measures. Currently, the acquisition of near-miss event data is limited by time and resources. Edge-based cameras offer a new, powerful method for continuously monitoring these events. This study introduces a multi-camera system for near-miss detection. It is designed to operate on a configuration of Technolution's Flowcubes in real-time and on edge. The system leverages rudimentary bounding-box information as input to maintain computational efficiency. It uses a stepwise approach, consisting of middle-point estimation, image-to-world projection, cross-camera association, and trajectory and size estimation. Finally, the resulting shared world-view facilitates the detection and classification of near-miss events. The system has been tested in both synthetic and real-world scenarios, demonstrating robust performance in deriving a cohesive world model, and promising results for near-miss event detection. It presents a scaleable solution for city-wide traffic safety monitoring with minimal infrastructure investment and reduced reliance on human supervision.
