Summary
This paper by Thomas Winkle (2016) addresses the challenge of quantifying the safety benefits of automated vehicles, particularly for highly and fully automated systems where real-world operational data is currently unavailable. The research is motivated by the need to validate safety prognoses for future automation levels using existing accident research. The author argues that while low-degree automation systems have established safety records, predicting the benefits of higher automation requires combining area-wide traffic, accident, weather, and vehicle operation data with traffic simulations and stochastic models. The study employs a meta-analytical approach, reviewing various accident data collections to demonstrate their potential and limitations in establishing safety benefits. It categorizes automation levels using frameworks from the German Federal Highway Research Institute (BASt), NHTSA, and SAE. The author evaluates several data sources, including German federal statistics, the German In-Depth Accident Study (GIDAS), US systems like FARS and Nass-CDS, Asian data collections, international databases like IRTAD and IGLAD, and proprietary data from manufacturers and insurance associations. The analysis distinguishes between "a-posteriori" evaluations of existing systems and "a-priori" forecasts for future technologies. A key methodological contribution is the differentiation between a system’s "area of action" (theoretical maximum impact) and its "degree of efficiency" (actual impact under real conditions), which depends on system specifications and driver behavior. Findings indicate that safety benefits for "driver-only" systems, such as Electronic Stability Control (ESC), can be scientifically verified through historical data, showing significant reductions in skid-related accidents. For assisted and partially automated systems, interdisciplinary studies combining technical, medical, and psychological expertise provide more accurate assessments. For example, an analysis of Lane Departure Warning systems highlighted the importance of understanding human errors like fatigue. A study of 100 reconstructed accidents involving current driver-assistance systems predicted a 27% reduction in injured persons, assuming optimal human-machine interaction and error-free system operation. However, the author notes that such small sample sizes lack statistical reliability. Larger analyses, such as those using the GIDAS database for connected vehicles, reveal the complexity of extrapolating data but offer valuable insights into potential accident avoidance. The significance of this work lies in its framework for validating automated vehicle safety through rigorous accident data analysis. It concludes that while current data supports the safety gains of low-level automation, predicting benefits for higher automation requires careful consideration of system limits and new risks. The paper advocates for combining in-depth accident reconstruction with large-scale statistical data and simulations to objectively evaluate safety benefits, thereby guiding the development, validation, and testing of future automated driving systems.
