Effectiveness of low speed autonomous emergency braking in real-world rear-end crashes

Accid Anal Prev. 2015 Aug;81:24-9. doi: 10.1016/j.aap.2015.03.029. Epub 2015 May 6.


This study set out to evaluate the effectiveness of low speed autonomous emergency braking (AEB) technology in current model passenger vehicles, based on real-world crash experience. The validating vehicle safety through meta-analysis (VVSMA) group comprising a collaboration of government, industry consumer organisations and researchers, pooled data from a number of countries using a standard analysis format and the established MUND approach. Induced exposure methods were adopted to control for any extraneous effects. The findings showed a 38 percent overall reduction in rear-end crashes for vehicles fitted with AEB compared to a comparison sample of similar vehicles. There was no statistical evidence of any difference in effect between urban (≤60 km/h) and rural (>60 km/h) speed zones. Areas requiring further research were identified and widespread fitment through the vehicle fleet is recommended.

Keywords: AEB technology; Effectiveness; Meta-analysis; Real-world; Rear-end crashes.
