Comparison of automated vehicle struck-from-behind crash rates with national rates using naturalistic data

In this study, automated vehicles in autonomous mode were found to be struck from behind at 4.8 times the rate of human-driven vehicles in a naturalistic driving study. When controlling for driving environment, the rates for AVs were 5.0 times higher for urban driving and not significant for business/industrial driving, although these results are for different manufacturers, complicating the results. Automated vehicles were more likely to be struck when stopped than when moving compared to human-driven vehicles, suggesting that automated vehicles' decisions about where and when to stop or remain stopped at intersections are more plausible contributing factors than unexpected rates of deceleration.PMID:33756426 | DOI:10.1016/j.aap.2021.106056
