Vehicle Safety Research

Keeping People Safe

To ensure continued advancement of technology, Periscope's focus on research identifies which technologies may have a significant impact on reducing crashes.

To do so, GM works with world-class research institutes to study how safety technologies currently available in vehicles are making a real-world difference on the path to a world with zero crashes. In this regard, GM has collaborated with organizations such as NHTSA, University of Michigan Transportation Research Institute (UMTRI), Insurance Institute for Highway Safety (IIHS) and Highway Loss Data Institute (HLDI).

Following a landmark police-report study conducted in 2019, which was updated in 2020, the GM and UMTRI teams analyzed the field effectiveness of GM advanced driver assistance systems and headlighting technology in reducing the occurrence of a wide range of common crashes that these features were designed to help avoid or mitigate. The research outcome demonstrates that much of this technology is making a statistically significant impact on helping to avoid crashes or mitigate injuries for occupants in the GM vehicles used in the analysis.

55%
reduced rear-end striking crashes with reported/possible injuries

Automatic Emergency Braking (or Forward Automatic Braking) with Forward Collision Alert reduced rear-end striking crashes by 40% and reduced rear-end striking crashes with reported or possible injuries by 55%

82%
reduced backing
crashes

The Reverse Automatic Braking feature, combined with Rear Vision Camera, Rear Park Assist and Rear Cross Traffic Alert, reduced backing crashes by 82%

26%
reduced nighttime
front crashes

IntelliBeam, which automatically turns a vehicle’s high beam headlamps on and off according to surrounding traffic conditions, reduced nighttime front crashes with a combined set of animals, pedestrians, and bicyclist crashes by 26%

16%
reduced lane
change crashes

Lane Change Alert with Side Blind Zone Alert reduced lane change crashes by 16%

17%
reduced lane departure-related crashes with reported/possible injuries

Lane Keep Assist with Lane Departure Warning reduced lane departure-related crashes by 12%, and reduced lane departure-related crashes with reported or possible injuries by 17%

The Safety Alert Seat provides directional seat vibrations to help alert drivers of the direction of potential crash threats detected by various active safety systems.

Because advanced driver assistance systems are critical to safety performance, how the driver is alerted and responds to these alerts also plays an important role to help ensure feature effectiveness in the field. Significant research has been conducted with VTTI to determine how best to communicate those alerts to the driver so that they can take action to help avoid a threat.

For example, the GM-exclusive Safety Alert Seat was developed with research conducted by VTTI, as well as TNO in the Netherlands. The Safety Alert Seat provides directional seat vibrations to help alert drivers of the direction of potential crash threats detected by various active safety systems. This haptic alert supplements available visual alerts and has been shown to be preferred by our customers and to increase ADAS usage.
