A groundbreaking study analyzing 21.2 million crashes across 98 million vehicles has revealed the remarkable effectiveness of autonomous emergency braking (AEB) technology. The research by the Partnership for Analytics Research in Traffic Safety (PARTS) provides compelling evidence that newer AEB systems can reduce front-to-rear crashes by more than half.
A Decade of Progress
| Model Years | Crash Reduction | Additional Benefits |
|---|---|---|
| 2015-2017 | 46% | Basic collision prevention |
| 2021-2023 | 52% | Enhanced pedestrian detection |
The data shows a clear evolution in AEB effectiveness, with modern systems proving significantly more capable than their predecessors. When paired with forward collision warning, the technology reduces nose-to-tail crashes by 49%, compared to just 13% for forward collision warning alone.
Protecting All Road Users
The study reveals AEB's broader impact on road safety:
- 9% reduction in collisions with vulnerable road users
- 53% decrease in injury likelihood with combined systems
- 28% reduction in vehicle occupant trauma (Monash University)
- 40% fewer rear-end crashes (Euro NCAP data)

Australian Market Impact
As Australia prepares to mandate AEB through ADR 98/00 from March 2025, the automotive landscape is already shifting. Several models unable to meet the new technical requirements will exit the market, including the Mazda 6 and multiple Mitsubishi models. This transition, while challenging for some manufacturers, signals a commitment to enhanced road safety.
The PARTS study provides irrefutable evidence of AEB's value in preventing crashes and saving lives. The technology's increasing effectiveness, particularly in newer vehicles, validates Australia's decision to make AEB mandatory. While some popular models may disappear from showrooms, the trade-off for significantly improved road safety appears well worth it.
As we approach the March 2025 deadline, this research suggests we're not just implementing new technology – we're embracing a proven life-saving innovation that continues to improve with each generation. The data makes it clear: AEB isn't just another safety feature; it's a revolutionary technology that's fundamentally changing road safety.
