Full Summary
Automated vehicles (AVs) aim to improve transportation safety, but they face challenges in handling rare and unexpected situations known as edge cases. This paper provides a systematic classification of edge case detection methods, organized by AV subsystems such as perception and trajectory-related components.
It introduces 'knowledge-driven' approaches that utilize expert insights to identify edge cases not present in training data, complementing traditional data-driven methods. The study evaluates detection techniques based on performance metrics, computational overhead, and domain-specific measures like crash rates.
Key challenges include issues with data availability, validation limitations, and the gap between simulation and real-world performance. By offering a structured review, this work aids in selecting appropriate detection methods for specific AV subsystems and supports practical testing through scenario generation.
