IIHS - Effects of AEB on Pedestrian Crash Risk

IIHS LogoThe Insurance Institute for Highway Safety (IIHS) has issued a report on Automatic Emergency Braking (AEB) and pedestrian crash risk. Current AEB systems with pedestrian detection are effective, but only during the daytime.

The study was published in the July 2022 edition of Accident Analysis & Prevention. A summary of the result states that:

AEB with pedestrian detection was associated with significant reductions of 25% - 27% in pedestrian crash risk and 29% - 30% in pedestrian injury crash risk. However, there was not evidence that that the system was effective in dark conditions without street lighting, at speed limits of 50 mph or greater, or while the AEB equipped vehicle was turning.

This should serve to reinforce that today's drivers cannot rely on Automated Driver Assistance Systems (ADAS). Drivers must understand how the ADAS systems in their vehicles do and do not work and rely on them as help in paying attention to the driving task, not a replacement.
