Automatic Emergency Braking (AEB) has proven to be remarkably effective in reducing rear-end collisions, according to a new study by Mitre. Analyzing data from 98 million vehicles and 21.2 million crashes in the U.S. between the 2015 and 2023 model years, the study found that AEB has cut rear-end crashes by an impressive 52 percent. This represents a significant improvement compared to a similar study conducted in 2022, which reported a 46 percent reduction. Overall, the presence of AEB reduced front-to-rear crashes by 49 percent compared to vehicles without the technology.
The impact of AEB extends beyond vehicle-on-vehicle collisions. The study also revealed a nine percent reduction in single-vehicle frontal crashes involving non-motorists, such as pedestrians, cyclists, scooters, and wheelchairs. This finding is particularly important because crashes involving non-motorists tend to be more severe and have a higher risk of fatalities. The Mitre study examined 168 different vehicle models, with Ford represented by a wide range of models, both current and discontinued.
This positive data on AEB stands in contrast to other studies that have shown limited or no positive impact from partial autonomy features on crash reduction. While AEB is demonstrating its life-saving potential, other driver-assistance technologies are still under scrutiny. The effectiveness of AEB reinforces the importance of its widespread adoption.
Recognizing the significant safety benefits of AEB, the National Highway Traffic Administration (NHTSA) had previously finalized a new Federal Motor Vehicle Safety Standard mandating AEB as standard equipment on all passenger cars and light trucks under 10,000 pounds by September 2029. However, this regulation is currently on hold following pushback from a lobby group backed by Ford and other automakers, as well as from several automakers themselves. Despite this setback, the data clearly demonstrates the critical role AEB plays in improving road safety.
