Study In the Real-World Finds Low-speed Autonomous Emergency Braking Works

A study published by a team of researchers in Europe, Australia and New Zealand has found that low-speed autonomous emergency braking (AEB) technology leads to a thirty-eight percent reduction in real-world rear-end crashes. The study was published in the journal Accident Analysis & Prevention. The study further found that the benefit is universal as there is little difference between urban and rural crash benefits.

There are two types of AEB, the low-speed variant often seen on European and as a standard feature on some higher-end vehicles here, and the standard version that’s often a feature on expensive luxury automobiles. The study specifically studied the low-speed version, which is more common in Europe where slower speeds are the norm rather than the exception and where most automotive accidents involving death and injury happen.

Low-speed AEB applies the brakes on a vehicle automatically if another vehicle, obstacle, or pedestrian is sensed by radar or other means at speeds under 35 mph. For the study, low-speed AEB was defined as that working at speeds under 50 km/h (31 mph). Unlike previous studies that have also found AEB to be beneficial, this new study was conducted using real-world data.

The findings showed a 38% overall reduction in real-world, rear-end crashes for vehicles fitted with low speed AEB compared to a sample of equivalent vehicles with no AEB. The study’s findings encouraged the rapid adoption of low-speed AEB in vehicles, calling it an “important active safety technology” that “should be encouraged in the interest of improved vehicle safety.”
