Automatic brakes halve rear-ending

Two new U.S. studies show that automatic emergency braking can cut the number of rearend automobile crashes in half, and reduce pickup truck crashes by more than 40%.

The studies released Tuesday, one by a government-auto industry partnership and the other by the insurance industry, each used crash data to make the calculations. Automatic emergency braking can stop vehicles if a crash is imminent, or slow them to reduce the severity.

Some automakers are moving toward a voluntary commitment by 20 companies to make the braking technology standard equipment on 95% of their light-duty models during the current model year that ends next August.

A study by The Partnership for Analytics Research in Traffic Safety compared data on auto equipment with 12 million police-reported crashes from 13 states that was collected by the National Highway Traffic Safety Administration, the partnership said in a statement Tuesday.

The group found frontto-rear crashes were cut 49% when the striking vehicle had forward collision alert plus automatic braking, when compared with vehicles that didn't have either system. Rear crashes with injuries were cut by 53%, the study found. Vehicles with forward collision warning systems only reduced rear-end crashes by 16%, and cut rear crashes with injuries by 19%. Automatic emergency braking works well in all conditions, even when roadway, weather or lighting conditions were not ideal, the study showed.
